Abstract Psoriasis, a chronic inflammatory skin disorder, is associated with comorbidities such as acute myocardial infarction (AMI). However, the molecular mechanisms connecting these conditions are unclear. In this study, we conducted bioinformatics analyses using gene expression datasets to identify differentially expressed genes and hub genes associated with both psoriasis and AMI. Our findings emphasize the involvement of immune-related pathways in the pathogenesis of both conditions. Furthermore, we investigated the expression levels of hub genes in AMI patients and myocardial infarction (MI) mice. ELISA measurements revealed significantly higher levels of CXCL8, IL1B, S100A9, and S100A12 in the serum of AMI patients compared to normal individuals. Immunohistochemical staining of heart tissue from MI mice showed a progressive increase in the expression of CXCL8 and IL-1B as MI advanced, while S100A9 exhibited high expression at day 3 post-MI. mRNA expression analysis validated these findings. Additionally, we explored the skin lesions of psoriasis patients and found significantly higher expression of CXCL8, IL-1B, S100A9, and S100A12 in the affected skin areas compared to unaffected regions. These results highlight the consistent upregulation of hub genes in both AMI and psoriasis patients, as well as in myocardial infarction mice, underscoring their potential as reliable markers for disease diagnosis. Moreover, molecular docking simulations revealed potential interactions between simvastatin and key target proteins, suggesting a potential therapeutic avenue. Overall, our study uncovers shared molecular signatures and potential therapeutic targets, providing a foundation for future investigations targeting common pathways in psoriasis and AMI.

BackgroundThe effectiveness and safety of a novel class of hypoglycemic medications known as sodium-glucose cotransporter 2 (SGLT2) inhibitors have not been completely established in relation to acute heart failure (AHF). Consequently, we sought to compare the prognostic and safety outcomes of patients administered SGLT2 inhibitors for the treatment of AHF.MethodsAn extensive search of the Web of Science, PubMed, and EMBASE was conducted for randomized controlled trials and observational studies that have evaluated the use of SGLT2 inhibitors in AHF from the inception of these drugs to the present. We compiled data related to cardiovascular safety and prognosis. Aggregated risk ratios (RR), mean differences (MD), or standardized mean differences (SMD) were generated for all outcomes, with 95% confidence intervals (CIs), to evaluate the predictive significance of SGLT2 inhibitors in patients with AHF.ResultsWe identified 4,053 patients from 13 studies. Patients experienced a substantial reduction in all-cause mortality (RR = 0.82, 95% CI: 0.70–0.96, P = 0.01), readmission rates (RR = 0.85, 95% CI: 0.74–0.98, P = 0.02), the number of heart failure exacerbation events (RR = 0.69, 95% CI: 0.50–0.95, P = 0.02), and the number of rehospitalization events due to heart failure (RR = 0.71, 95% CI: 0.58–0.86, P

Summary: Endothelial cell dysfunction contributes to age-related vascular diseases. Analyzing public databases and mouse tissues, we found decreased MFN2 expression in senescent endothelial cells and angiotensin II-treated mouse aortas. In human endothelial cells, Ang II reduced MFN2 expression while increasing senescence markers P21 and P53. siMFN2 treatment worsened Ang II-induced senescence, while MFN2 overexpression alleviated it. siMFN2 or Ang II treatment caused mitochondrial dysfunction and morphological abnormalities, including increased ROS production and reduced respiration, mitigated by ovMFN2 treatment. Further study revealed that BCL6, a negative regulator of MFN2, significantly contributes to Ang II-induced endothelial senescence. In vivo, Ang II infusion decreased MFN2 expression and increased BCL6, P21, and P53 expression in vascular endothelial cells. The shMfn2+Ang II group showed elevated senescence markers in vascular tissues. These findings highlight MFN2’s regulatory role in endothelial cell senescence, emphasizing its importance in maintaining endothelial homeostasis and preventing age-related vascular diseases.

Abstract Background CREG1 (cellular repressor of E1A‐stimulated genes 1) is a protein involved in cellular differentiation and homeostasis regulation. However, its role in skeletal muscle satellite cells differentiation and muscle regeneration is poorly understood. This study aimed to investigate the role of CREG1 in myogenesis and muscle regeneration. Methods RNA sequencing data (GSE8479) was analysed from the Gene Expression Omnibus database (GEO, https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi). We generated Creg1 knockdown and skeletal muscle satellite cells specific Creg1 overexpression mice mediated by adeno‐associated virus serotype 9 (AAV9), skeletal muscle mature myofibre Creg1 knockout mice (myoblast/Creg1MKO), and control mice Creg1flox/flox (Creg1fl/fl) as in vivo models. The mice were injected into tibialis anterior (TA) muscle with 100 μL of 10 μM cardiotoxin to establish a muscle regeneration model. Creg1fl/fl and Creg1MKO mice were treated with AAV‐sh‐C‐Cbl (2 × 1010 genomic copies/mouse) to silence C‐Cbl in the TA muscle. 293T and C2C12 cells were transfected with plasmids using lipofectamine RNAi MAX in vitro. Mass spectrometry analyses and RNA sequencing transcriptomic assay were performed. Results We analysed the transcriptional profiles of the skeletal muscle biopsies from healthy older (N = 25) and younger (N = 26) adult men and women in GSE8479 database, and the results showed that Creg1 was associated with human sarcopenia. We found that Creg1 knockdown mice regenerated less newly formed fibres in response to cardiotoxin injection (~30% reduction, P

Pancreatic cancer is one of the most lethal cancers with significant radioresistance and tumor repopulation after radiotherapy. As a type of short non-coding RNA that regulate various biological and pathological processes, miRNAs might play vital role in radioresistance. We found by miRNA sequencing that microRNA-26a (miR-26a) was upregulated in pancreatic cancer cells after radiation, and returned to normal state after a certain time. miR-26a was defined as a tumor suppressive miRNA by conventional tumor biology experiments. However, transient upregulation of miR-26a after radiation significantly promoted radioresistance, while stable overexpression inhibited radioresistance, highlighting the importance of molecular dynamic changes after treatment. Mechanically, transient upregulation of miR-26a promoted cell cycle arrest and DNA damage repair to promote radioresistance. Further experiments confirmed HMGA2 as the direct functional target, which is an oncogene but enhances radiosensitivity. Moreover, PTGS2 was also the target of miR-26a, which might potentiate tumor repopulation via delaying the synthesis of PGE2. Overall, this study revealed that transient upregulation of miR-26a after radiation promoted radioresistance and potentiated tumor repopulation, highlighting the importance of dynamic changes of molecules upon radiotherapy.

Abstract Benzopyrene (B[a]P) is a well-known carcinogen that can induce chronic inflammation and fibrosis in the liver, leading to liver disease upon chronic exposure. Nonalcoholic steatohepatitis (NASH) is a chronic liver condition characterized by fat accumulation, inflammation, and fibrosis, often resulting in hepatocellular carcinoma (HCC). In this study, we aimed to investigate the intricate connections between B[a]P exposure, NASH, and HCC. Through comprehensive bioinformatics analysis of publicly available gene expression profiles, we identified differentially expressed genes (DEGs) associated with B[a]P exposure, NASH, and liver cancer. Furthermore, network analysis revealed hub genes and protein–protein interactions, highlighting cellular metabolic dysfunction and disruption of DNA damage repair in the B[a]P-NASH-HCC process. Notably, HSPA1A and PPARGC1A emerged as significant genes in this pathway. To validate their involvement, we conducted qPCR analysis on cell lines and NASH mouse liver tissues and performed immunohistochemistry labeling in mouse and human HCC liver sections. These findings provide crucial insights into the potential regulatory mechanisms underlying benzopyrene-induced hepatotoxicity, shedding light on the pathogenesis of B[a]P-associated NASH and HCC. Moreover, our study suggests that HSPA1A and PPARGC1A could serve as promising therapeutic targets. Enhancing our understanding of their regulatory roles may facilitate the development of targeted therapies, leading to improved patient outcomes.

Abstract Background The use of a tourniquet in combination with tranexamic acid (TXA) not only ensures clear vision, reduces intraoperative blood loss and shortens operative time but also improves cement-bone inter-digitation in total knee arthroplasty (TKA). However, there is no proof whether the blood flow blocking effect of tourniquet affects the antifibrinolytic effect of TXA, and the optimal timing of TXA administration is still unclear. Therefore, this study aims to investigate the effect of the first dose of TXA administered intravenously before tourniquet compression and release in TKA on perioperative blood loss and therapeutic efficacy in patients. Methods In this double-blind trial, 90 patients undergoing primary TKA were randomised into 2 groups: Group A, patients received intravenous TXA 10 min before tourniquet compression (20 mg/kg) and 3, 6 and 24 h later (10 mg/kg), and Group B, patients were treated the same as those in Group A but received intravenous TXA before tourniquet release. The primary outcomes were changes in blood loss, haemoglobin and haematocrit. Secondary outcomes included operation and tourniquet times, blood transfusion rate, subcutaneous petechiae and circumferential changes in the operated limb, visual analogue scale (VAS) score, hospital for special surgery (HSS) score, length of stay (LOS) postoperatively, complications and patient satisfaction. Results No statistically significant difference was found between the 2 groups with regard to age, sex, weight, body mass index (BMI), Kellgren-Lawrence class, preoperative blood volume, preoperative laboratory values, operation and tourniquet times, transfusion rate, knee circumference, preoperative HSS, or VAS score (P:n.s.). There was no significant difference in intraoperative blood loss (IBL) (52.7 ml vs. 63.4 ml, P = 0.07), hidden blood loss (HBL) (91.4 ml vs. 119.9, P = 0.4) or total blood loss (TBL) (144.1 ml vs. 183.3 ml, P = 0.72) between Groups A and B. Haemoglobin, haematocrit and red blood cell count (RBC) dropped to a low point on postoperative day 3 and then rebounded, returning to normal levels on day 21, and the trend of change between the 2 groups was not statistically significant (P:n.s.). There was no significant difference in subcutaneous ecchymosis incidence, knee swelling rate, HSS score, VAS score, LOS postoperatively, complication rate or patient satisfaction (P:n.s.). Conclusion TXA was administered intravenously prior to tourniquet compression could effectively reduce blood loss in patients who had undergone total knee arthroplasty. However, there was no significant difference in knee swelling rate, subcutaneous bruising and petechiae incidence, knee function, complication rate or satisfaction between patients who TXA was given intravenously before tourniquet compression and release in primary TKA.

Background: Identifying germline mutations in BRCA1 and BRCA2 genes (BRCAs) would benefit the carriers in multiple aspects. In addition to single-nucleotide variations and small indels, copy number variations (CNVs) is also an indispensable component of identifiable mutations in BRCAs. A sensitive, rapid and throughput-flexible method to detect CNVs would be preferred to meet the rising clinical requirements for BRCAs testing.Methods: We developed a MALDI-TOF-MS-based method (MS assay) which included three steps: first, multiplex end-point PCR followed by a single base extension reaction; second, automated analyte transfer and data acquisition; third, data analysis. We applied MS assay to detect CNVs in BRCAs in 293 Chinese patients with ovarian or pancreatic cancer. All the samples were examined by targeted next-generation sequencing (TS) simultaneously. Samples were further cross-validated by multiplex ligation-dependent probe amplification (MLPA) if the results from MS assay and TS were inconsistent. Long range PCR was then applied to identify the exact breakpoints in BRCAs.Results: MS assay introduced highly multiplexed panels to detect CNVs of BRCAs semi-quantitatively. Simplified on-board data analysis was available for MS assay and no complex bioinformatics was needed. The turnaround time of MS assay was less than 8 hours with a hands-on time of only 40 min. Compared to TS, MS assay exhibited higher sensitivity (100% vs. 75%) and was more flexible in throughput, with the reagent cost per sample remaining constant no matter how many samples were examined per assay. A total of eight CNVs in BRCAs were detected from the 293 samples, and the molecular breakpoints were successfully identified in five samples through long-range PCR followed by Sanger sequencing.Conclusion: Our results suggested that MS assay might be an effective method in primary screening for CNVs in genes such as BRCAs, especially when short turnaround time and/or high sensitivity is a top priority.

Abstract Fibroblast growth factor 21 (FGF21) is a pleiotropic hormone secreted primarily by the liver and is considered a major regulator of energy homeostasis. Recent research has revealed that FGF21 could play an important role in cardiac pathological remodeling effects and prevention of cardiomyopathy; however, the underlying mechanism remains largely unknown. This study aimed to determine the mechanism underlying the cardioprotective effects of FGF21. We engineered FGF21 knock out mice and subsequently elucidated the effects of FGF21 and its downstream mediators using western blotting, qRT-PCR, and mitochondrial morphological and functional analyses. FGF21 knockout mice showed cardiac dysfunction, accompanied by a decline in global longitudinal strain (GLS) and ejection fraction (EF), independent of metabolic disorders. Mitochondrial quality, quantity, and function were abnormal, accompanied by decreased levels of optic atrophy-1 (OPA1) in FGF21 KO mice. In contrast to FGF21 knockout, cardiac-specific overexpression of FGF21 alleviated the cardiac dysfunction caused by FGF21 deficiency. In an in vitro study, FGF21 siRNA deteriorated mitochondrial dynamics and impaired function induced by cobalt chloride (CoCl2). Both recombinant FGF21 and adenovirus-mediated FGF21 overexpression could alleviate CoCl2-induced mitochondrial impairment by restoring mitochondrial dynamics. FGF21 was essential for maintaining mitochondrial dynamics and function of the cardiomyocytes. As a regulator of cardiomyocyte mitochondrial homeostasis under oxidative stress, FGF21 could be an important new target for therapeutic options for patients with heart failure.

Consuming fish oil is linked to reduced risk of cardiovascular disease in some populations, but the effects are not consistent across studies. Here the authors report that smooth muscle cell AMPKα2 is required for the protective effects of fish oil on atherosclerosis in mice, and acts via post-translational regulation of the fatty acid receptor GPR120.

Abstract. Objective:. Pressure overload-induced myocardial apoptosis is a critical pathologically initiated process leading to heart failure (HF). Growth differentiation factor 15 (GDF15) dramatically increases during cardiac hypertrophy and dysfunction, but its functions and mechanisms are barely known. This study aims to elucidate the role and mechanism of GDF15 in HF. Methods:. Between January 2017 and August 2018, 57 patients diagnosed with chronic HF (aged >18 years, with left ventricular ejection fraction (LVEF) ≤35%) and 57 non-HF patients (aged >18 years, LVEF >35%) were prospectively enrolled in this study based on the balance of the baseline characteristics. Other acute or chronic diseases and pregnant/lactating women were excluded. The serum concentrations of GDF15 were detected. Isoproterenol (ISO)-induced HF mouse model was established by pumping with ISO (30 mg/(kg·day)) for 4 weeks, and the GDF15 expression in serum and heart tissue was evaluated in vivo. Primary cardiomyocytes were cultured and treated with ISO to induce cardiomyocytes damage. The apoptosis of cardiomyocytes and the effect of GDF15 on ISO-induced cardiomyocytes injury was evaluated in vitro. Results:. After adjusting the baseline characteristic, serum levels of GDF15 were significantly higher in HF subjects than in non-HF patients. Similarly, in the ISO-induced HF mouse model, the significant increase in GDF15 was associated with the process of HF in vivo. Moreover, the elevation of GDF15 occurred prior to heart remodeling in the ISO-induced HF mouse model. Furthermore, using primary cardiomyocytes, we demonstrated that the GDF15 was remarkably enhanced in serum from pathological HF patients and cardiac tissue from the ISO-induced mouse model. Reducing GDF15 exaggerated the ISO-induced cell apoptosis by blocking mitochondrial fusion and increasing oxidative stress. In contrast, the silence of GDF15 aggravated the ISO-induced cardiomyocytes damage. Conclusions:. GDF15 acts as a protective factor against cardiomyocyte apoptosis by improving mitochondria fusion during HF. These findings indicate that GDF15 may be a potential therapeutic target for HF.

“Government, bank, and guarantee institution” cooperative financing guarantee (hereinafter referred to as the cooperation mechanism) is an important way to alleviate the financing difficulties of China’s new agricultural entities and raise the credit line of bank financing. In order to find an effective way for the improvement of low-level equilibrium in the actual operation of the cooperation mechanism, this study builds a three-party evolutionary game model using the local government, banks, and agricultural guarantee institutions, with incomplete information on all partners of the cooperation mechanism as the study object. This model focuses on the weak activeness, strong dependence, poor cooperation effect, lower credit line of guarantee, and other specific problems. Moreover, this study analyzes the equilibrium solution of this model and extracts the significant factors affecting the positive cooperation behaviors of the three parties (government, banks, and guarantee institutions) in the view of interest realization. Analog simulation is performed to explore the key conditions for truly alleviating the financing risks of new agricultural entities, thus helping improve the operation quality of the cooperation mechanism. According to the study results, the focus of “government, bank, and guarantee institution” cooperation should be shifted from post risk sharing to prior risk identification. Specifically, the government should further share high-quality information affiliated with farmland management rights and reflecting the status of risks; guide banks and agricultural guarantee institutions should share the cost of risk identification, accelerate the acquisition of higher information transformation value, and prevent the “free rider problem.” In the last part, policies are recommended in four aspects, including risk information sharing, risk identification quality improvement, risk identification cost sharing, and risk information value transformation, which have practical guiding significance for the sustainable development of “government, bank, and guarantee institution” financing guarantee for China’s new agricultural entities.

Abstract. Objective:. Fish oil (FO) contains omega-3 that inhibits inflammation and blood lipid metabolism, giving it a protective cardiovascular effect. Due to dietary habits, a majority of large-scale clinical trials examining FO and cardiovascular health have been conducted in the Caucasian populations. However, the effects of FO on cardiovascular inflammation indicators and blood lipid metabolism in the Chinese population remain unclear. This study aimed to perform a meta-analysis to elucidate the impact of FO on cardiovascular health in the Chinese population. Methods:. Web searches were utilized to locate records of clinical trials related to cardiovascular health and consumption of FO capsules or fish containing omega-3 in several databases, including PubMed, Medline, Embase, Cochrane Library, CNKI, and ClinicalTrial.gov, etc. We obtained lipid metabolism and related proinflammatory markers as the study outcome. We used Review Manager 5.4 and Stata 16 for the statistical analysis. If the I2 ≥ 30%, a random effects model was used, and if the I2 < 30%, a fixed effects model was used. Results:. Twenty eligible trials were shortlisted from >1000 records. The meta-analysis revealed that supplementation with eicosapentaenoic acid and docosahexaenoic acid reduced systolic blood pressure by 1.88 mmHg (95% CI: −4.97 to −1.20, P = 0.23), diastolic blood pressure by 0.86 mmHg (95% CI: −1.79 to 0.06, P = 0.07), fasting blood glucose by 0.05 mmol/L (95% CI: −0.16 to 0.06, P = 0.40), and low-density lipoprotein-cholesterol by 0.12 mmol/L (95% CI: −0.23 to −0.01, P = 0.04), when compared to placebo. However, these supplements increased high-density lipoprotein-cholesterol by 0.03 mmol/L (95% CI: 0.01 to 0.05, P

Backgrounds. Cardiovascular disease (CVD) is a serious condition that poses threats to patients’ quality of life and life expectancy. Cardiac rehabilitation is a crucial treatment option that can improve outcomes for CVD patients. Hybrid comprehensive telerehabilitation (HCTR) is a relatively new approach. In the context of pandemics, HCTR can minimize the risk of cluster infections by reducing hospital visits while delivering effective rehabilitation care. This study is aimed at assessing the efficacy and safety of HCTR as a secondary prevention measure for CVD patients compared to usual rehabilitation care. Methods. We searched PubMed, Embase, The Web of Science, The Cochrane Library, and PsychINFO for all related studies up to January 20, 2023. Two reviewers independently screened the titles and abstracts of potentially eligible articles based on the predefined search criteria. Data were analyzed using a comprehensive meta-analysis software (RevMan5.3). Results. Eight trials, involving 1578 participants, were included. HCTR and usual rehabilitation care provide similar effects on readmission rates (odds ratio OR=0.90 (95% CI 0.69-1.17), P=0.43) and mortality (odds ratio OR=1.06 (95% CI 0.72-1.57), P=0.76). Effects on Short Form-36 Health Status Questionnaire (SF-36) score were also similar (SMD: 1.32 (95% CI-0.48-3.11), P=0.15). Compared with usual rehabilitation care, HCTR can improve peak oxygen uptake (VO2 peak) (SMD: 0.99 (95% CI 0.23-1.74), P=0.01) and 6-minute walking test (6MWT) (SMD: 10.02 (95% CI 5.44-14.60), P

The cytosolic DNA-sensing cGAS-STING pathway has been proved to be involved in tumor progression and influence the effect of cancer immunotherapy. However, little attentions have been paid to the role of cGAS-STING pathway on cancer stemness. Herein, we found that the cGAS-STING pathway was activated in different tumor cells. cGAS- or STING-knockout impaired the capability of tumor formation in vivo and tumorsphere formation in vitro. In addition, loss of cGAS-STING cascade promoted tumor apoptosis, but inhibited tumor growth and metastasis. We further demonstrated that cGAS-STING pathway potentiated tumor formation by sustaining cancer stemness. Moreover, analysis of RNA-seq showed that cGAS-STING pathway maintained cancer stemness probably by activating STAT3. Our findings highlight the role of intrinsic activation of cGAS-STING pathway in tumorigenesis, and reveal a new mechanism of its regulation of tumor progression via sustaining cancer stemness through STAT3 activation.
