- Abstract
OBJECTIVE: Cakile maritima scop. (CKM) is a herbaceous plant (Brassicaceae) growing also in high salinity environment. It is an annual plant growing in clumps or mounds in the sand on beaches and bluffs. MATERIALS AND METHODS: Stems, seeds, leaves and flowers of CKM were used to obtain 70% of ethanol extracts. The phenolic content of the different extracts was evaluated by the Folin-Ciocalteu method. The separation of phytochemical compounds was based on ultra- performance liquid chromatography coupled to mass spectrometry. Radical scavenging activity was determined by 1,1-diphenyl-2-picrylhydrazyl assay. The qualitative assay for the inhibition of α-glucosidase was quantified spectrophotometrically and the anti-inflammatory activity was determined in the U937 cell line by using gene expression of pro-inflammatory cytokines. Cell viability assay was done in U937, MM1S, and U266 cells by using the 3-(4,5-Dimethyl- 2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay. The antimicrobial activity was investigated by MIC determination, "double- triple combinations assay", and growth inhibition curves analysis, using the extracts individually or in various combination. Statistical analysis was performed by the Student's t-test and ANOVA. RESULTS: All parts of the plant exhibited a high antioxidant capacity as measured by DPPH assay. Furthermore, all extracts reduced (about 10 folds) the expression of inflammatory cytokines in macrophage following LPS treatment. As regards the antibacterial activity, only the seeds extract was able to inhibit both Gram-negative and Gram-positive bacteria when tested alone, whereas dual combinations of different extracts (leaves, flowers, stems and seeds) caused bacterial inhibition exhibiting a synergic action. Finally, we showed that the extracts did not exhibit cytotoxic effects in normal cells and that, surprisingly, it exhibited an anti-proliferative effect (inhibition ≈80%) in multiple myeloma U266 cells. CONCLUSIONS: Our study suggests that CKM possesses antioxidant, anti-inflammatory, antibacterial, anti-proliferative activities and such pleiotropic effects may be exploited under various pathological conditions.

- Abstract
OBJECTIVE: In this study we evaluated the possible protective effect of an antioxidant formulation containing microfiltered milk derived polypeptides, Curcumin, Vitamin B2, Carnitine and N-Acetyl-cysteine (NAC) in an in vitro model of chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: Human bronchial epithelial cells (16HBE) were used in this study. Cells were treated for 24 h in the presence or absence of 10% of cigarette smoke extract (CSE) and in the presence or absence of antioxidant formulation. We evaluated cell viability by MTT assay, reactive oxygen species by flow cytometer and quantitative analysis of gene expression by Real-time PCR. RESULTS: The data obtained showed a significant increase of cell viability in CSE-exposed cells and a significant reduction of reactive oxygen species (ROS) production compared to cells treated with only CSE. The antioxidant effects of formulation were confirmed by a decrease of inflammatory cytokines genes IL-1β, IL-6, TNFα, nitric oxide synthase gene (NOS2) and through an induction of antioxidant genes such as heme oxygenase 1 (HO-1), nuclear transcription factor erythroid 2 (NRF2) and peroxisome proliferator-activated receptor gamma coactivator- 1 alpha (PGC-1α). CONCLUSIONS: The results suggest that antioxidants combination plays a protective role on oxidative stress and inflammation, in an in vitro model of COPD, activating key genes in response to oxidative stress and decreasing the cytokines responsible for the inflammatory pathways.

- Abstract
OBJECTIVE: Moringa oleifera Lam., a multipurpose tree, is used traditionally for its nutritional and medicinal properties. It has been used for the treatment of a variety of conditions, including inflammation, cancer and metabolic disorders. MATERIALS AND METHODS: We investigated the effect of Moringa oleifera Lam. on adipogenic differentiation of human adipose-derived mesenchymal stem cells and its impact on lipid metabolism and cellular antioxidant systems. RESULTS: We showed that Moringa oleifera Lam. treatment during adipogenic differentiation reduces inflammation, lipid accumulation and induces thermogenesis by activation of uncoupling protein 1 (UCP1), sirtuin 1 (SIRT1), peroxisome proliferator-activated receptor alpha (PPARα), and coactivator 1 alpha (PGC1α). In addition, Moringa oleifera Lam. induces heme oxygenase-1 (HO-1), a well established protective and antioxidant enzyme. Finally Moringa oleifera Lam. significantly decreases the expression of molecules involved in adipogenesis and upregulates the expression of mediators involved in thermogenesis and lipid metabolism. CONCLUSIONS: Our results suggest that Moringa oleifera Lam. may promote the brown remodeling of white adipose tissue inducing thermogenesis and improving metabolic homeostasis. [ABSTRACT FROM AUTHOR]

Background Sigma-1 receptors (σ 1 R) are highly expressed in neurons as well as microglia and have been shown to modulate the inflammatory response in the central nervous system and thus may serve as possible target for neuroprotective strategies. The aim of the present study was to test the effect of (+)-pentazocine, a putative σ 1 R agonist, in an in vitro model of microglia activation. Methods Microglia (BV2 cells) was exposed (3 h) to 1% oxygen and reoxygenation was allowed for 24 h. Cells were treated with different concentrations (1, 10, 25 and 50 μM) of (+)-pentazocine in the presence or absence of NE-100 (1 μM), a well established σ 1 R antagonist. Cell viability and apoptosis were measured by cytofluorimetric analysis, whereas oxidative stress was evaluated by reduced glutathione (GSH) content and mitochondrial potential analysis. Results Our results showed that (+)-pentazocine was able to increase cell viability and restore mitochondrial potential at all concentrations whereas only 1 and 10 μM were able to reduce significantly apoptotic cell death, to restore reduced glutathione intracellular content and prevent ERK1/2 phosphorylation. All these effects were abolished by concomitant treatment with NE-100. Conclusions: (+)-pentazocine exhibits significant dose dependent protective effects in our in vitro model of microglial activation thus suggesting that σ 1 R may represent a possible target for neuroprotection.

Background and Objective: Associations between dyslipidaemia, oxidative stress and periodontitis have emerged in recent years. However, there is a lack of studies investigating these associations in aggressive periodontitis (AgP) cases. The aim of this study was to investigate the lipid and oxidative stress profiles in patients with AgP, and to relate them to clinical variables and interleukin (IL)-6 genetic variants. Material and Methods: Twelve non-smoking Caucasian patients with AgP selected based on their IL6 haplotypes underwent periodontal non-surgical and surgical treatment. Peripheral blood samples taken at baseline and at six different time-points after treatment were processed to determine IL-6 circulating levels, lipid profiles (cholesterol, triglycerides, high-density lipoprotein [HDL] and low-density lipoprotein [LDL] subclasses) and oxidative stress markers (glutathione and total lipid hydroperoxide levels). Results: HDLs were the most prevalent lipoproteins, followed by intermediate-density lipoprotein, very-low-density lipoprotein and LDL. The LDL subclasses consisted mainly of the less atherogenic large LDL. The lipid profile did not consistently change after treatment up to 3 mo after surgery. Periodontal disease severity was associated with LDL levels and size. The IL6 haplotypes were associated with total cholesterol, triglycerides, HDL and LDL subclasses after adjusting for confounders. IL-6 circulating levels were associated with both very-low-density lipoprotein and lipid hydroperoxide levels. Conclusion: Based on these data, we conclude that both periodontal disease severity and IL6 haplotypes may influence lipid profiles in AgP. © 2015 John Wiley & Sons A/S. Published by John Wiley

Context: Liraglutide is a glucagon-like peptide-1 analog and glucose-lowering agent whose effects on cardiovascular risk markers have not been fully elucidated. Objective: We evaluated the effect of liraglutide on markers of oxidative stress, heme oxygenase-1 (HO-1), and plasma ghrelin levels in patients with type-2 diabetes mellitus (T2DM). Design and Setting: A prospective pilot study of 2 months' duration has been performed at the Unit of Diabetes and Cardiovascular Prevention at University of Palermo, Italy. Patients and Intervention(s): Twenty subjects with T2DM (10 men and 10 women; mean age: 57 ± 13 y) were treated with liraglutide sc (0.6 mg/d for 2 wk, followed by 1.2 mg/d) in addition to metformin (1500 mg/d orally) for 2 months. Patients with liver disorders or renal failure were excluded. Main Outcome Measure(s): Plasma ghrelin concentrations, oxidative stress markers, and heat-shock proteins, including HO-1 were assessed. Results: The addition of liraglutide resulted in a significant decrease in glycated hemoglobin (HbA1c) (8.5 ± 0.4 vs 7.5 ± 0.4%, P < .0001). In addition, plasma ghrelin and glutathione concentrations increased (8.2 ± 4.1 vs 13.6 ± 7.3 pg/ml, P = .0007 and 0.36 ± 0.06 vs 0.44 ± 0.07 nmol/ml, P = .0002, respectively), whereas serum lipid hydroperoxides and HO-1 decreased (0.11 ± 0.05 vs 0.04 ± 0.07 pg/ml, P = .0487 and 7.7 ± 7.7 vs 3.6 ± 1.8 pg/ml, P = .0445, respectively). These changes were not correlated with changes in fasting glycemia or HbA1c. Conclusions: In a 2-months prospective pilot study, the addition of liraglutide to metformin resulted in improvement in oxidative stress as well as plasma ghrelin and HO-1 concentrations in patients with T2DM. These findings seemed to be independent of the known effects of liraglutide on glucose metabolism.

Molecular chaperones and the heat shock response play a major role in the maintenance of cellular homeostasis under various pathological conditions. In particular, their role is to regulate protein conformation, protect proteins from misfolding and aggregation, and maintain signalling and organellarnetworks. Among variousheat shock proteins, Hsp32 also known as heme oxygenase-1 (HO-1), has demonstrated an important role in metabolic syndrome. In particular, the HO system seems to play a major role in the complex pathophysiological cascade involved in insulin resistance mechanisms, and adipocyte functions as measured by the release of important adipokynes. The aim of the present review is to point out the role of HO-1 in metabolic syndrome, and how to exploit its beneficial effects as a therapeutic strategy to prevent complicationsof andto improve insulin sensitivity.

Significance: Many physiological effects of natural antioxidants, their extracts or their major active components, have been reported in recent decades. Most of these compounds are characterized by a phenolic structure, similar to that of α-tocopherol, and present antioxidant properties that have been demonstrated both in vitro and in vivo. Polyphenols may increase the capacity of endogenous antioxidant defenses and modulate the cellular redox state. Such effects may have wide-ranging consequences for cellular growth and differentiation. Critical Issues: The majority of in vitro and in vivo studies conducted so far have attributed the protective effect of bioactive polyphenols to their chemical reactivity toward free radicals and their capacity to prevent the oxidation of important intracellular components. One possible protective molecular mechanism of polyphenols is nuclear factor erythroid 2-related factor (Nrf2) activation, which in turn regulates a number of detoxification enzymes. Recent Advances: Among the latter, the heme oxygenase-1 (HO-1) pathway is likely to contribute to the established and powerful antioxidant/anti-inflammatory properties of polyphenols. In this context, it is interesting to note that induction of HO-1 expression by means of natural compounds contributes to prevention of cardiovascular diseases in various experimental models. Future Directions: The focus of this review is on the role of natural HO-1 inducers as a potential therapeutic strategy to protect the cardiovascular system against various stressors in several pathological conditions.

Nonalcoholic steatohepatitis (NASH) is associated with increased liver-related mortality. Disturbances in hepatic lipid homeostasis trigger oxidative stress and inflammation (ie, lipotoxicity), leading to the progression of NASH. This study aimed at identifying whether silibinin may influence the molecular events of lipotoxicity in a mouse model of NASH. Eight-week-old db/db mice were fed a methionine-choline deficient (MCD) diet for 4 weeks and treated daily with silibinin (20 mg/kg intraperitoneally) or vehicle. Liver expression and enzyme activity of stearoyl-CoA desaturase-1 and acyl-CoA oxidase, and expression of liver fatty acid-binding protein were assessed. Hepatic levels of reactive oxygen species, thiobarbituric acid-reactive substances (TBARS), 3-nitrotyrosine (3-NT), inducible nitric oxide synthase (iNOS), and nuclear factor kappa B (NFkB) activities were also determined. Silibinin administration decreased serum alanine aminotransferase and improved liver steatosis, hepatocyte ballooning, and lobular inflammation in db/db mice fed an MCD diet. Gene expression and activity of stearoyl-CoA desaturase-1 were reduced in db/db mice fed an MCD diet compared with lean controls and were increased by silibinin; moreover, silibinin treatment induced the expression and activity of acyl-CoA oxidase and the expression of liver fatty acid-binding protein. Vehicle-treated animals displayed increased hepatic levels of reactive oxygen species and TBARS, 3-NT staining, and iNOS expression; silibinin treatment markedly decreased reactive oxygen species and TBARS and restored 3-NT and iNOS to the levels of control mice. db/db mice fed an MCD diet consistently had increased NFkB p65 and p50 binding activity; silibinin administration significantly decreased the activity of both subunits. Silibinin treatment counteracts the progression of liver injury by modulating lipid homeostasis and suppressing oxidative stress-mediated lipotoxicity and NFkB activation in experimental NASH.

- Abstract
Muscle damage resulting from physical activities such as exercise triggers an immune response crucial for tissue repair and recovery. This study investigates the immune cell profiles in muscle biopsies of individuals engaged in resistance exercise (RE) and explores the impact of age and sex on the immune response following exercise-induced muscle damage. Microarray datasets from muscle biopsies of young and old subjects were analyzed, focusing on the gene expression patterns associated with immune cell activation. Genes were compared with immune cell signatures to reveal the cellular landscape during exercise. Results show that the most significant modulated gene after RE was Folliculin Interacting Protein 2 (FNIP2) a crucial regulator in cellular homeostasis. Moreover, the transcriptome was stratified based on the expression of FNIP2 and the 203 genes common to the groups obtained based on sex and age. Gene ontology analysis highlighted the FLCN-FNIP1-FNIP2 complex, which exerts as a negative feedback loop to Pi3k-Akt-mTORC1 pathway. Furthermore, we highlighted that the young females exhibit a distinct innate immune cell activation signature compared to males after a RE session. Specifically, young females demonstrate a notable overlap with dendritic cells (DCs), M1 macrophages, M2 macrophages, and neutrophils, while young males overlap with M1 macrophages, M2 macrophages, and motor neurons. Interestingly, in elderly subjects, both sexes display M1 macrophage activation signatures. Comparison of young and elderly signatures reveals an increased M1 macrophage percentage in young subjects. Additionally, common genes were identified in both sexes across different age groups, elucidating biological functions related to cell remodeling and immune activation. This study underscores the intricate interplay between sex, age, and the immune response in muscle tissue following RE, offering potential directions for future research. Nevertheless, there is a need for further studies to delve deeper and confirm the dynamics of immune cells in response to exercise-induced muscle damage., Competing Interests: Declarations Competing interests The authors declare no competing interests., (© 2024.

- Abstract
Background: Human Milk (HM) is a dynamic nourishment; its composition is influenced by several conditions such as gestational age, maternal diet and ethnicity. It appears important to evaluate the impact that gestational pathologies have on HM components and if their presence, as a source of oxidative stress in the mother, influence milk's redox homeostasis. To assess the effect of Preeclampsia (PE) and Gestational Diabetes Mellitus (GDM) on some aspects of human milk redox homeostasis, we chose to investigate both oxidative and antioxidant aspects, with, respectively, Lipid hydroperoxides (LOOHs) and Glutathione (GSH)., Methods: Women with PE, GDM and who were healthy were recruited for this study. Colostrum, transitional and mature milk samples were collected. GSH and LOOHs levels were measured using a spectrophotometric test. To investigate the effect of pathology on redox homeostasis, a mixed linear model with unistructural covariance structure was performed., Results: A total of 120 mothers were recruited. The GSH concentration results were significantly lower in GDM women than in healthy women only in colostrum ( p < 0.01). No other differences emerged. LOOHs was not detectable in almost all the samples., Discussion: Our study is the first to extensively evaluate these components in the HM of women with these gestational pathologies. The main observation is that GDM can alter the GSH level of HM, mainly in colostrum.

- Abstract
Background: It is known that preeclampsia affects lactogenesis. However, data on the effects of this pathology on human milk neurobiomarker composition are not available. The aim of this study is to investigate the effects of this gestational pathology on activin A levels, a neurobiomarker known to play an important role in the development and protection of the central nervous system., Methods: The women recruited were divided in two different study groups: preeclamptic or normotensive women. All the human milk samples were collected using the same procedure. Activin A was quantified using an Enzyme-linked immunosorbent assay (ELISA) test. To investigate the effect of preeclampsia on the activin A concentration in the three lactation phases, a mixed linear model with a unistructural covariance structure, with the mother as the random effect, and fixed effects were performed., Results: Activin A was detected in all samples. There were no significant differences between preeclamptic and normotensive women. The only significant effect is related to the lactation phase: the difference between colostrum and mature milk ( p < 0.01) was significant. In conclusion, these results allow us to affirm that breast milk's beneficial properties are maintained even if preeclampsia occurs.

- Abstract
Hypertension and derived cardiovascular disease (CVD) are among the leading causes of death worldwide. Increased oxidative stress and inflammatory state are involved in different alterations in endothelial functions that contribute to the onset of CVD. Polyphenols, and in particular anthocyanins, have aroused great interest for their antioxidant effects and their cardioprotective role. However, anthocyanins are rarely detected in blood serum because they are primarily metabolized by the gut microbiota. This review presents studies published to date that report the main results from clinical studies on the cardioprotective effects of anthocyanins and the role of the gut microbiota in the metabolism and bioavailability of anthocyanins and their influence on the composition of the microbiota. Even if it seems that anthocyanins have a significant effect on vascular health, more studies are required to better clarify which molecules and doses show vascular benefits without forgetting the crucial role of the microbiota.

- Abstract
Tumor onset and its progression are strictly linked to its metabolic rewiring on the basis of the Warburg effect. In this context, fumarate emerged as a putative oncometabolite mediating cancer progression. Fumarate accumulation is usually driven by fumarate hydratase (FH) loss of function, the enzyme responsible for the reversible conversion of fumarate into malate. Fumarate accumulation acts as a double edge sword: on one hand it takes part in the metabolic rewiring of cancer cells, while on the other it also plays a crucial role in chromatin architecture reorganization. The latter is achieved by competing with a-ketoglutarate-dependent enzymes, eventually altering the cellular methylome profile, which in turn leads to its transcriptome modeling. Furthermore, in recent years, it has emerged that FH has an ability to recruit DNA double strand breaks. The accumulation of fumarate into damaged sites might also determine the DNA repair pathway in charge for the seizure of the lesion, eventually affecting the mutational state of the cells. In this work, we aimed to review the current knowledge on the role of fumarate as an oncometabolite orchestrating the cellular epigenetic landscape and DNA repair machinery.

- Abstract
Background: The consumption of 100% fruit juices has not been associated with substantial detrimental outcomes in population studies and may even contribute to improving the cardiometabolic profile if included in a healthy balanced diet. The main contributors to such potential beneficial effects include vitamins, minerals, and likely the (poly)phenol content. This study aimed to investigate whether the (poly)phenols contained in 100% fruit juices may mediate their effects on cardiometabolic risk factors based on published randomized controlled trials (RCT)., Methods: A systematic search in PubMed/MEDLINE and Embase, updated till the end of October 2022, was carried out to identify RCT providing quantitative data on (poly)phenol content in 100% fruit juices and used as an intervention to improve cardiometabolic parameters such as blood lipids, glucose, and blood pressure. Meta-regression analysis was performed to calculate the effect of the intervention [expressed as standardized mean difference and 95% confidence intervals (CI)] using the (poly)phenol content as moderator., Results: A total of 39 articles on RCT investigating the effects of 100% fruit juices on cardiometabolic risk factors reporting data on total (poly)phenol and anthocyanin content were included in the analysis. Total (poly)phenol content was substantially unrelated to any outcome investigated. In contrast, each 100 mg per day increase in anthocyanins was related to 1.53 mg/dL decrease in total cholesterol (95% CI, -2.83, -0.22, p = 0.022) and 1.94 mg/dL decrease in LDL cholesterol (95% CI, -3.46, -0.42, p = 0.012). No other potential mediating effects of anthocyanins on blood triglycerides, glucose, systolic and diastolic pressure were found, while a lowering effect on HDL cholesterol after excluding one outlier study was observed., Discussion: In conclusion, the present study showed that anthocyanins may mediate the potential beneficial effects of some 100% fruit juices on some blood lipids. Increasing the content of anthocyanins through specific fruit varieties or plant breeding could enhance the health benefits of 100% fruit juices., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Micek, Currenti, Mignogna, Rosi, Barbagallo, Alshatwi, Del Rio, Mena and Godos.)

- Abstract
Although mangiferin (MGN) is a natural antioxidant that could be a good candidate for the treatment of ocular diseases, its use in ophthalmology is strongly compromised due to its high lipophilicity. Its encapsulation in nanostructured lipid carriers (NLC) seems to be an interesting strategy for improving its ocular bioavailability. As reported in our previous work, MGN-NLC showed high ocular compatibility and fulfilled the nanotechnological requirements needed for ocular delivery. The aim of the present work was to investigate, in vitro and ex vivo, the capability of MGN-NLC to act as a potential drug delivery system for MGN ocular administration. The data obtained in vitro on arising retinal pigment epithelium cells (ARPE-19) did not show cytotoxic effects for blank NLC and MGN-NLC; likewise, MGN-NLC showed the maintenance of the antioxidant role of MGN by mitigating ROS (Reactive Oxygen Species) formation and GSH (glutathione) depletion induced by H
2 O2 . In addition, the capacity of MGN-released to permeate through and accumulate into the ocular tissues was confirmed ex vivo using bovine corneas. Finally, the NLC suspension has been formulated as a freeze-dried powder using mannitol at a concentration of 3% ( w / v ) in order to optimize its storage for long periods of time. All this evidence suggests a potential application of MGN-NLC in the treatment of oxidative stress-related ocular diseases.- Published

- Abstract
Chronic myeloid leukemia (CML), BCR-ABL1-positive, is classified as a myeloproliferative characterized by Philadelphia chromosome/translocation t(9;22) and proliferating granulocytes. Despite the clinical success of tyrosine kinase inhibitors (TKi) agents in the treatment of CML, most patients have minimal residual disease contained in the bone marrow microenvironment, within which stromal cells assume a pro-inflammatory phenotype that determines their transformation in cancer-associated fibroblasts (CAF) which, in turn can play a fundamental role in resistance to therapy. Insulin-like Growth Factor Binding Protein-6 (IGFBP-6) is expressed during tumor development, and is involved in immune-escape and inflammation as well, providing a potential additional target for CML therapy. Here, we aimed at investigating the role of IGFBP-6/SHH/TLR4 axis in TKi response. We used a CML cell line, LAMA84-s, and healthy bone marrow stromal cells, HS-5, in mono- or co-culture. The two cell lines were treated with Dasatinib and/or IGFBP-6, and the expression of inflammatory markers was tested by qRT-PCR; furthermore, expression of IGFBP-6, TLR4 and Gli1 were evaluated by Western blot analysis and immumocytochemistry. The results showed that both co-culture and Dasatinib exposure induce inflammation in stromal and cancer cells so that they modulate the expression of TLR4, and these effects were more marked following IGFBP-6 pre-treatment suggesting that this molecule may confer resistance through the inflammatory processes. This phenomenon was coupled with sonic hedgehog (SHH) signaling. Indeed, our data also demonstrate that HS-5 treatment with PMO (an inducer of SHH) induces significant modulation of TLR4 and overexpression of IGFPB-6 suggesting that the two pathways are interconnected with each other and with the TLR-4 pathway. Finally, we demonstrated that pretreatment with IGFBP-6 and/or PMO restored LAMA-84 cell viability after treatment with Dasatinib, suggesting that both IGFBP-6 and SHH are involved in the resistance mechanisms induced by the modulation of TLR-4, thus indicating that the two pathways may be considered as potential therapeutic targets.

- Abstract
This article intends to reflect on the validation of psychiatric semiology and nosography that is taught in clinical psychologists and psychiatrists training programs. The vision of academic psychiatry of our times, strongly influenced by scientific narrative, seeks to consolidate an universal nosography that aims to erase the culture marks. However, the prevalence of certain diagnoses over others is determined by the social context and cultural changes that determine, in turn, the classifying standards of professionals. For this reason, it is important to include the contributions of public intellectuals and cultural theorists for an updated and culturalized semiology of clinical phenomena. We will use the developments of Mark Fisher on Capitalist Realism to rethink the main symptoms of depression., Competing Interests: The authors have no conflicts of interest to declare., (Creative Commons BY-NC-ND 4.0)

- Abstract
Uveal melanoma (UM), the most common primary intraocular cancer in adults, is among the tumors with poorer prognosis. Recently, the role of the oncometabolite lactate has become attractive due to its role as hydroxycarboxylic acid receptor 1 (HCAR1) activator, as an epigenetic modulator inducing lysine residues lactylation and, of course, as a glycolysis end-product, bridging the gap between glycolysis and oxidative phosphorylation. The aim of the present study was to dissect in UM cell line (92.1) the role of lactate as either a metabolite or a signaling molecule, using the known modulators of HCAR1 and of lactate transporters. Our results show that lactate (20 mM) resulted in a significant decrease in cell proliferation and migration, acting and switching cell metabolism toward oxidative phosphorylation. These results were coupled with increased euchromatin content and quiescence in UM cells. We further showed, in a clinical setting, that an increase in lactate transporters MCT4 and HCAR1 is associated with a spindle-shape histological type in UM. In conclusion, our results suggest that lactate metabolism may serve as a prognostic marker of UM progression and may be exploited as a potential therapeutic target.

- Abstract
The growing interest in natural bioactive molecules, as an approach to many pathological contexts, is widely justified by the necessity to overcome the disadvantageous benefit-risk ratio related to traditional therapies. Among them, mangiferin (MGF) shows promising beneficial properties such as antioxidant, anti-inflammatory, and immunomodulatory effects. In this study, we aimed to investigate the antioxidant and anti-inflammatory properties of MGF on lipopolysaccharide (LPS)-induced lung NCI-H292 cells, focusing on its role against COVID-19 adsorption. In order to obtain this information, cells treated with LPS, with or without MGF, were analyzed performing wound healing, gene expression of inflammatory cytokines, GSH quantification, and JC-1 staining. Moreover, the inhibition of viral adsorption was evaluated microbiologically and the results were further confirmed by molecular docking analysis. In this regard, MGF downregulates the expression of several inflammatory factors, enhances GSH levels, promotes the wound healing rate, and restores the mitochondrial dysfunction caused by LPS. In addition, MGF significantly inhibits SARS-CoV-2 adsorption as shown by the gene expression of ACE2 and TMPRSS-2, and furtherly confirmed by microbiological and molecular modeling evaluation. Although more investigations are still needed, all data obtained constitute a solid background, demonstrating the cytoprotective role of MGF in inflammatory mechanisms including COVID-19 infection.

- Abstract
Colorectal cancer (CRC) is one of the most common cancers in the world. Here, we undertook an analysis of microarray datasets consisting of colon biopsies of healthy subjects and of patients affected by CRC, in order to analyze the expression levels of Chitinase domain-containing protein 1 (CHID1) and to correlate them with the clinical data available in the datasets. Analysis of expression levels showed a significant increase of CHID1 in CRC biopsies compared to the mucosa of healthy subjects. Patients' stratification by TNM staging revealed significant increases in CHID1 expression levels as the disease progressed. Furthermore, we found that mutated BRAF patients exhibit higher levels of CHID1 expression. Patients with a poor surviving prognosis at 5 years expressed high levels of CHID1 compared to wild-type. The histochemical analysis carried out by the Human Protein Atlas web tool documented moderate to strong-intensity staining detection of CHID1 protein in CRC biopsies. Furthermore, CRC patients were selected and clustered into two groups, high and low CHID1 expression levels (HCEL and LCEL). We obtained two signatures, the genes significant positive (GSPC-CHID1) and negative (GSNC-CHID1) correlated to CHID1 expression levels. The genomic deconvolution analysis between the GSPC-CHID1, GSNC-CHID1, and 17 cell immunological signatures, highlighted the potential infiltration of Macrophages M0 in HCEL patients, and potential infiltration of Macrophages M1 cells in LCEL patients. In addition, the signature GSPC-CHID1 expressed unfavorable genes to the CRC patient's survival. Mirror results were obtained for the GSNC-CHID1 signature. From the outcome of our investigation, it is possible to conclude that HCEL are associated with an unfavorable prognosis for CRC patients., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2022 Elsevier GmbH.

- Abstract
It is well recognized that functional foods rich in antioxidants and antiinflammation agents including polyphenols, probiotics/prebiotics, and bioactive compounds have been found to have positive effects on the aging process. In particular, fruits play an important role in regular diet, promoting good health and longevity. In this study, we investigated on biological properties of extract obtained from Mangifera indica L. leaves in preclinical in vitro models. Specifically, the profile and content of bioactive compounds, the antimicrobial potential toward food spoilage and pathogenic bacterial species, and the eventually protective effect in inflammation were examined. Our findings revealed that MLE was rich in polyphenols, showing a content exclusively in the subclass of benzophenone/xanthone metabolites, and these phytochemical compounds demonstrated the highest antioxidant capacity and greatest in vitro antibacterial activity toward different bacterial species such as Bacillus cereus , B. subtilis , Pseudomonas fluorescens , Staphylococcus aureus , and St. haemolyticus . Furthermore, our data showed an in vitro anti-inflammatory, antioxidant, and antifibrotic activity.

- Abstract
Human behavior is influenced by both genetic and environmental factors. Monoamine oxidase A (MAOA) is among the most investigated genetic determinants of violent behaviors, while the monoamine oxidase B (MAOB) is explored in Parkinson's disease. We collected twenty-four post-mortem brain tissue datasets of 3871 and 1820 non-demented males and females, respectively, who died from causes not attributable to neurodegenerative diseases. The gene expressions of MAOA and MAOB (MAO genes) were analyzed in these subjects, who were further stratified according to age into eleven groups ranging from late Infancy (5-9 months) to centenarians (>100 years). MAO genes were differently expressed in brains during the entire life span. In particular, maximal and minimal expression levels were found in early life and around the teen years. Females tended to have higher MAO gene levels throughout their lives than those found in age-matched males, even when expressions were separately measured in different brain regions. We demonstrated the existence of age- and sex- related variations in the MAO transcript levels in defined brain regions. More in-depth protein studies are needed to confirm our preliminary results obtained only on messenger RNAs in order to establish the role played by MAO genes in human development., (Copyright © 2021 Elsevier B.V.

- Abstract
In order to maintain redox homeostasis, non-small-cell lung cancer (NSCLC) increases the activation of many antioxidant systems, including the heme-oxygenase (HO) system. The overexpression of HO-1 has been often associated with chemoresistance and tumor aggressiveness. Our results clearly showed an overexpression of the HO-1 protein in A549 NSCLC cell lines compared to that in non-cancerous cells. Thus, we hypothesized that "off-label" use of tin mesoporphyrin, a well-known HO activity inhibitor clinically used for neonatal hyperbilirubinemia, has potential use as an anti-cancer agent. The pharmacological inhibition of HO activity caused a reduction in cell proliferation and migration of A549. SnMP treatment caused an increase in oxidative stress, as demonstrated by the upregulation of reactive oxygen species (ROS) and the depletion of glutathione (GSH) content. To support these data, Western blot analysis was performed to analyze glucose-6-phosphate dehydrogenase (G6PD), TP53-induced glycolysis and the apoptosis regulator (TIGAR), and the glutamate cysteine ligase catalytic (GCLC) subunit, as they represent the main regulators of the pentose phosphate pathway (PPP) and glutathione synthesis, respectively. NCI-H292, a subtype of the NSCLC cell line, did not respond to SnMP treatment, possibly due to low basal levels of HO-1, suggesting a cellular-dependent antitumorigenic effect. Altogether, our results suggest HO activity inhibition may represent a potential target for selective chemotherapy in lung cancer subtypes.

- Abstract
Recent findings demonstrated that physical exercise has a powerful role in improving cognitive function and delaying age-associated neurological decline. However, to date, there is a lack of information regarding the effect of physical activity (PA) on brain cells architecture. In this paper, we hypothesized that PA could play a role in the transcriptional changes of genes that enrich the main cells of central nervous system (CNS). From NCBI, we selected a microarray dataset composed of the human hippocampi (GSE110298) from 23 cognitively intact clinical cases (NDHSs) (aged 87.4 ± 6.3 years) selected to from the Rush Memory and Aging Project (MAP). The significantly expressed genes, obtained comparing hippocampi from subjects who underwent Low Physical Activity (LPA) vs those who performed High Physical Activity (HPA), were overlapped with the main genes enriching the CNS cells, obtained from the public human brain single-cell RNA-sequencing dataset (GSE67835), in order to determine the respective weighted percentages of significantly expression genes modulation (WPSEG). In NDHSs underwent HPA, the WPSEG was higher for Neurons, Dendritic Development, Synaptic transmission genes and Axon Development. In addition, in NDHSs underwent LPA we observed high expression of genes enriching Oligodendrocytes, Microglia, and Endothelial cells. Furthermore, neurogenesis and the decreasing of the T cell-mediated inflammatory process were the two main molecular mechanisms activated in the brains of NDHSs underwent HPA. From our results, it is possible to conclude that, in elderly subjects, the transcriptional profile of CNS cells changes as a function of the PA conducted during life. Performing PA periodically supports the maintenance of the physiological balance of neuronal cells and, consequently, improves the quality of life of the elderly., (Copyright © 2021 Elsevier B.V.

In recent years, there has been a growth in scientific interest in nutraceuticals, which are those nutrients in foods that have beneficial effects on health. Nutraceuticals can be extracted, used for food supplements, or added to foods. There has long been interest in the antiviral properties of nutraceuticals, which are especially topical in the context of the ongoing COVID-19 pandemic. Therefore, the purpose of this review is to evaluate the main nutraceuticals to which antiviral roles have been attributed (either by direct action on viruses or by modulating the immune system), with a focus on the pediatric population. Furthermore, the possible applications of these substances against SARS-CoV-2 will be considered.

- Abstract
Background: SARS-CoV2, the agent responsible for the current pandemic, is also causing respiratory distress syndrome (RDS), hyperinflammation and high mortality. It is critical to dissect the pathogenetic mechanisms in order to reach a targeted therapeutic approach., Methods: In the present investigation, we evaluated the effects of SARS-CoV
2 on human bronchial epithelial cells (HBEC). We used RNA-seq datasets available online for identifying SARS-CoV2 potential genes target on human bronchial epithelial cells. RNA expression levels and potential cellular gene pathways have been analyzed. In order to identify possible common strategies among the main pandemic viruses, such as SARS-CoV2 , SARS-CoV1, MERS-CoV, and H1N1, we carried out a hypergeometric test of the main genes transcribed in the cells of the respiratory tract exposed to these viruses., Results: The analysis showed that two mechanisms are highly regulated in HBEC: the innate immunity recruitment and the disassembly of cilia and cytoskeletal structure. The granulocyte colony-stimulating factor (CSF3) and dynein heavy chain 7, axonemal (DNAH7) represented respectively the most upregulated and downregulated genes belonging to the two mechanisms highlighted above. Furthermore, the carcinoembryonic antigen-related cell adhesion molecule 7 (CEACAM7) that codifies for a surface protein is highly specific of SARS-CoV2 and not for SARS-CoV1, MERS-CoV, and H1N1, suggesting a potential role in viral entry. In order to identify potential new drugs, using a machine learning approach, we highlighted Flunisolide, Thalidomide, Lenalidomide, Desoximetasone, xylazine, and salmeterol as potential drugs against SARS-CoV2 infection., Conclusions: Overall, lung involvement and RDS could be generated by the activation and down regulation of diverse gene pathway involving respiratory cilia and muscle contraction, apoptotic phenomena, matrix destructuration, collagen deposition, neutrophil and macrophages recruitment., (Copyright © 2020 Elsevier Inc.
