- Abstract
[Display omitted] • Haskap derived C3G feeding blunts weight gain and ectopic liver fat accumulation. • Haskap derived C3G feeding downregulate hepatic lipogenic gene expression in DIO. • Haskap derived C3G feeding remodel gut microbiome composition. Haskap (Lonicera caerulea L.) berry is enriched in anthocyanins, primarily cyanidin-3- O -β-glucoside (C3G). It remains unknown whether C3G counteracts metabolic alterations of the pathogenesis of obesity. In this study, mice were fed high-fat high-sucrose (HFHS) diet supplemented either with C3G-rich extract (HFHS + CE) or berry powder with low C3G (HFHS + BP). Mice fed HFHS + CE displayed short-term protection against weight gain, independent of food intake. HFHS + CE mice had lower hepatic diacylglycerols and triacylglycerols content and reduced expression of key lipogenic transcription factors. These metabolic changes also translated into improved glucose tolerance and insulin sensitivity. 16S rRNA sequencing revealed altered gut microbiota composition in the HFHS + CE group. In summary, we demonstrate that C3G enrichment in the HFHS diet attenuates short-term weight gain, decreases hepatic lipid content by suppressing key lipogenic gene expression and improves glucose homeostasis during obesity development, supporting the therapeutic utility of C3G as a bioactive phytonutrient to manage obesity-related complications.

- Abstract
The DNA-alkylating metabolite tilimycin is a microbial genotoxin. Intestinal accumulation of tilimycin in individuals carrying til+ Klebsiella spp. causes apoptotic erosion of the epithelium and colitis. Renewal of the intestinal lining and response to injury requires the activities of stem cells located at the base of intestinal crypts. This study interrogates the consequences of tilimycin-induced DNA damage to cycling stem cells. We charted the spatial distribution and luminal quantities of til metabolites in Klebsiella -colonized mice in the context of a complex microbial community. Loss of marker gene G6pd function indicates genetic aberrations in colorectal stem cells that became stabilized in monoclonal mutant crypts. Mice colonized with tilimycin-producing Klebsiella displayed both higher frequencies of somatic mutation and more mutations per affected individual than animals carrying a non-producing mutant. Our findings imply that genotoxic til+ Klebsiella may drive somatic genetic change in the colon and increase disease susceptibility in human hosts. [Display omitted] • Tilimycin is a microbiota-derived enteric mutagen • Large quantities of genotoxin accumulate in the intestine of colonized mice • Tilimycin permeates the depths of colonic crypts • Genotoxic Klebsiella induces mutation in murine colorectal epithelial stem cells Bacteria belonging to the human gut microbiota produce DNA-damaging metabolites. Pöltl et al. colonize mice with genotoxic Klebsiella oxytoca to show that tilimycin, the mutagenic peptide it produces, is distributed across the intestinal tract. Tilimycin exposure over a timescale of days drives somatic mutation in colorectal epithelial stem cells. [ABSTRACT FROM AUTHOR]

- Abstract
Summary Helicobacter pylori is a late-in-life human pathogen with potential early-life benefits. Although H. pylori is disappearing from the human population, little is known about the influence of H. pylori on the host’s microbiota and immunity. Studying the interactions of H. pylori with murine hosts over 6 months, we found stable colonization accompanied by gastric histologic and antibody responses. Analysis of gastric and pulmonary tissues revealed increased expression of multiple immune response genes, conserved across mice and over time in the stomach and more transiently in the lungs. Moreover, H. pylori infection led to significantly different population structures in both the gastric and intestinal microbiota. These studies indicate that H. pylori influences the microbiota and host immune responses not only locally in the stomach, but distantly as well, affecting important target organs.

Maintenance of circadian alignment between an organism and its environment is essential to ensure metabolic homeostasis. Synchrony is achieved by cell autonomous circadian clocks. Despite a growing appreciation of the integral relation between clocks and metabolism, little is known regarding the direct influence of a peripheral clock on cellular responses to fatty acids. To address this important issue, we utilized a genetic model of disrupted clock function specifically in cardiomyocytes in vivo (termed cardiomyocyte clock mutant (CCM)). CCM mice exhibited altered myocardial response to chronic high fat feeding at the levels of the transcriptome and lipidome as well as metabolic fluxes, providing evidence that the cardiomyocyte clock regulates myocardial triglyceride metabolism. Time-of-day-dependent oscillations in myocardial triglyceride levels, net triglyceride synthesis, and lipolysis were markedly attenuated in CCM hearts. Analysis of key proteins influencing triglyceride turnover suggest that the cardiomyocyte clock mactivates hormone-sensitive lipase during the active/awake phase both at transcriptional and post-translational (via AMP-activated protein kinase) levels. Consistent with increased net triglyceride synthesis during the end of the active/awake phase, high fat feeding at this time resulted in marked cardiac steatosis. These data provide evidence for direct regulation of triglyceride turnover by a peripheral clock and reveal a potential mechanistic explanation for accelerated metabolic pathologies after prevalent circadian misalignment in Western society.

Triacyiglycerol accumulation in insulin target tissues is associated with insulin resistance. Paradoxically, mice with global targeted deletion of adipose triglyceride lipase (ATGL), the rate- limiting enzyme in triacyiglycerol hydrolysis, display improved glucose tolerance and insulin sensitivity despite triacyiglycerol accumulation in multiple tissues. To determine the molecular mechanisms for this phenotype, ATGL-deficient (ATGL-/-) and wild-type mice were injected with saline or insulin (10 units / kg, intraperitoneally), and then phosphorylation and activities of key insulin-signaling proteins were determined in insulin target tissues (liver, adipose tissue, and muscle). Insulin signaling and!or glucose transport was also evaluated in isolated adipocytes and skeletal muscle ex vivo. In ATGL-/- mice, insulin-stimulated phosphatidylinositol 3-kinase and Akt activities as well as phosphorylation of critical residues ofiRSi (Tyr(P)-612) and Akt (Ser(P)-473) were increased in skeletal muscle in vivo. Insulin-stimulated phosphatidylinositol 3-kinase activity and total insulin receptor and insulin receptor substrate 1, but not other parameters, were also increased in white adipose tissue in vivo. In contrast, in vivo measures of insulin signaling were decreased in brown adipose tissue and liver. Interestingly, the enhanced components of insulin signaling identified in skeletal muscle and white adipose tissue in vivo and their expected downstream effects on glucose transport were not present ex vivo. ATGL deficiency altered intramyocellular lipids as well as [ABSTRACT FROM AUTHOR]

Neuropathy target esterase (NTE) is a member of the family of patatin domain-containing proteins and exhibits phospholipase activity in brain and cultured cells. NTE was originally identified as target enzyme for organophosphorus compounds that cause a delayed paralyzing syndrome with degeneration of nerve axons. Here we show that the structurally related murine protein NTE-related esterase (NRE) is a potent lysophospholipase. The enzyme efficiently hydrolyzes sn-1 esters in lysophosphatidylcholine and lysophosphatidic acid. No lipase activity was observed when triacylglycerols, cholesteryl esters, retinyl esters, phosphatidylcholine, or monoacylglycerol were used as substrates. Although NTE is predominantly expressed in the nervous system, we found the highest NRE mRNA levels in testes, skeletal muscle, cardiac muscle, and adipose tissue. Induction of NRE mRNA concentrations in these tissues during fasting suggested a nutritional regulation of enzyme expression and, in accordance with this observation, insulin reduced NRE mRNA levels in a dose-dependent manner in 3T3-L1 adipocytes. A green fluorescent protein-NRE fusion protein colocalized to the endoplasmic reticulum and lipid droplets. Thus, NRE is a previously unrecognized ER- and lipid droplet-associated lysophospholipase. Regulation of enzyme expression by the nutritional status and insulin suggests a role of NRE in the catabolism of lipid precursors and/or mediators that affect energy metabolism in mammals.

Summary: Adipose triglyceride lipase (ATGL) was recently identified as an important triacylglycerol (TG) hydrolase promoting the catabolism of stored fat in adipose and nonadipose tissues. We now demonstrate that efficient ATGL enzyme activity requires activation by CGI-58. Mutations in the human CGI-58 gene are associated with Chanarin-Dorfman Syndrome (CDS), a rare genetic disease where TG accumulates excessively in multiple tissues. CGI-58 interacts with ATGL, stimulating its TG hydrolase activity up to 20-fold. Alleles of CGI-58 carrying point mutations associated with CDS fail to activate ATGL. Moreover, CGI-58/ATGL coexpression attenuates lipid accumulation in COS-7 cells. Antisense RNA-mediated reduction of CGI-58 expression in 3T3-L1 adipocytes inhibits TG mobilization. Finally, expression of functional CGI-58 in CDS fibroblasts restores lipolysis and reverses the abnormal TG accumulation typical for CDS. These data establish an important biochemical function for CGI-58 in the lipolytic degradation of fat, implicating this lipolysis activator in the pathogenesis of CDS. [Copyright &y& Elsevier]

Triple-negative breast cancer (TNBC) poses significant challenges for treatment given the lack of targeted therapies and increased probability of relapse. It is pertinent to identify vulnerabilities in TNBC and develop newer treatments. Our prior research demonstrated that transcription factor EB (TFEB) is necessary for TNBC survival by regulating DNA repair, apoptosis signaling, and the cell cycle. However, specific mechanisms by which TFEB targets DNA repair and cell cycle pathways are unclear, and whether these effects dictate TNBC survival is yet to be determined. Here, we show that TFEB knockdown decreased the expression of genes and proteins involved in DNA replication and cell cycle progression in MDA-MB-231 TNBC cells. DNA replication was decreased in cells lacking TFEB, as measured by EdU incorporation. TFEB silencing in MDA-MB-231 and noncancerous MCF10A cells impaired progression through the S-phase following G1/S synchronization; however, this proliferation defect could not be rescued by co-knockdown of suppressor RB1. Instead, TFEB knockdown reduced origin licensing in G1 and early S-phase MDA-MB-231 cells. TFEB silencing was associated with replication stress in MCF10A but not in TNBC cells. Lastly, we identified that TFEB knockdown renders TNBC cells more sensitive to inhibitors of Aurora Kinase A, a protein facilitating mitosis. Thus, inhibition of TFEB impairs cell cycle progress by decreasing origin licensing, leading to delayed entry into the S-phase, while rendering TNBC cells sensitive to Aurora kinase A inhibitors and decreasing cell viability. In contrast, TFEB silencing in noncancerous cells is associated with replication stress and leads to G1/S arrest. [ABSTRACT FROM AUTHOR]

Toxin-producing Klebsiella oxytoca causes antibiotic-associated haemorrhagic colitis (AAHC). The disease-relevant cytotoxins tilivalline and tilimycine produced by certain K. oxytoca isolates are encoded by the non-ribosomal peptide synthetase genes A (npsA) and B (npsB). In this study, the new LightMix® Modular kit for the detection of relevant K. oxytoca sensu lato (s.l.) toxin genes was evaluated. DNA was extracted on the automated EMAG® platform. Amplification was done on the Light Cycler® 480 II instrument. In total, 130 residual faecal specimens collected from patients with antibiotic-associated diarrhoea were studied to determine the clinical sensitivity and specificity. Toxigenic culture served as reference method. With the new kit, the limit of detection was 15 CFU/mL for all targets. For the pehX target specific to K. oxytoca s.l., 65 of 130 clinical specimens were positive, while toxin-specific targets (npsA / npsB) were positive in 47 of 130. The npsA / npsB PCR targets showed a clinical sensitivity of 100% (95%CI 80.5–100%) and a specificity of 73.5% (95%CI 64.3–81.3%) with a positive predictive value of 16.5% (95%CI 12.7–21.2%) and a negative predictive value of 100%. Compared with culture, additional clinical specimens positive for K. oxytoca s.l. were detected with real-time PCR. The specificity of the toxin targets appears moderate due to the inferior sensitivity of the culture-based reference method. Since the developed assay is highly sensitive, it may be used as first-line method to improve the diagnosis of AAHC. [ABSTRACT FROM AUTHOR]

Essential anticancer medicines are an indispensable component of multidisciplinary treatment of paediatric malignancies. A European Society for Medical Oncology (ESMO) study reported inequalities in the availability of anticancer medicines for adult solid tumours and provided a model for the present survey. The aim of this survey was to assess the accessibility of essential medicines used in paediatric cancer patients aged 0 to 18 years across Europe from 2016 to 2018. A list of medicines was drawn with input from the European Society for Paediatric Oncology (SIOP Europe) Clinical Research Council referring to the World Health Organization Model List of Essential Medicines for Children (WHO EMLc) 2017. A survey was sent to nominated national clinician and pharmacist rapporteurs and parent associations in up to 37 countries; answers were obtained from 34 countries. The full survey list contained 68 medicines, including 24 on the WHO EMLc 2017. Health professionals reported that 35% of all medicines were prescribed off-label in at least one country and that 44% were always available in >90% of countries. Only 63% of the EMLc 2017 medicines were reported as always available. The main determinant of unavailability was shortages, reported for 72% of medicines in at least one country. Out-of-pocket costs were reported in eight countries. Twenty-seven percent of orally administered medicines were never available in child-friendly formulations. Parents detailed individual efforts and challenges of facilitating ingestion of oral medicines as prescribed. Inequalities in access to pain control during procedures were reported by parents across Europe. Children and adolescents with cancer in Europe experience lack of access to essential medicines. Urgent actions are needed to address shortages, financial accessibility, availability of safe age-appropriate oral formulations, and pain management across Europe. • Shortages were the main reason for the unavailability of essential medicines used to treat paediatric cancers in Europe. • Financial barriers applied mostly in lower-income countries and to newly approved expensive medicines across all settings. • Lack of child-friendly formulations caused concerns over alignment with the prescribed protocol and parental distress. • There were marked differences between countries in access to pain control for children undergoing invasive procedures. • Urgent action is needed to ensure equal access to essential medicines used to treat paediatric cancers in Europe.

INSULIN , *MYOCARDIUM , *HEART diseases , *SKELETAL muscle , *HEART cells , *NATALIZUMAB - Abstract
Branched-chain a-keto acids (BCKAs) are catabolites of branched-chain amino acids (BCAAs). Intracellular BCKAs are cleared by branched-chain ketoacid dehydrogenase (BCKDH), which is sensitive to inhibitory phosphorylation by BCKD kinase (BCKDK). Accumulation of BCKAs is an indicator of defective BCAA catabolism and has been correlated with glucose intolerance and cardiac dysfunction. However, it is unclear whether BCKAs directly alter insulin signaling and function in the skeletal and cardiac muscle cell. Furthermore, the role of excess fatty acids (FAs) in perturbing BCAA catabolism and BCKA availability merits investigation. By using immunoblotting and ultra-performance liquid chromatography MS/MS to analyze the hearts of fasted mice, we observed decreased BCAAcatabolizing enzyme expression and increased circulating BCKAs, but not BCAAs. In mice subjected to diet-induced obesity (DIO), we observed similar increases in circulating BCKAs with concomitant changes in BCAA-catabolizing enzyme expression only in the skeletal muscle. Effects of DIO were recapitulated by simulating lipotoxicity in skeletal muscle cells treated with saturated FA, palmitate. Exposure of muscle cells to high concentrations of BCKAs resulted in inhibition of insulin- induced AKT phosphorylation, decreased glucose uptake, and mitochondrial oxygen consumption. Altering intracellular clearance of BCKAs by genetic modulation of BCKDK and BCKDHA expression showed similar effects on AKT phosphorylation. BCKAs increased protein translation and mTORC1 activation. Pretreating cells with mTORC1 inhibitor rapamycin restored BCKA's effect on insulin-induced AKT phosphorylation. This study provides evidence for FA-mediated regulation of BCAA-catabolizing enzymes and BCKA content and highlights the biological role of BCKAs in regulating muscle insulin signaling and function.

Childhood cancer survivors (CCS), of whom there are about 500,000 living in Europe, are at an increased risk of developing health problems [1–6] and require lifelong Survivorship Care. There are information and knowledge gaps among CCS and healthcare providers (HCPs) about requirements for Survivorship Care [7–9] that can be addressed by the Survivorship Passport (SurPass), a digital tool providing CCS and HCPs with a comprehensive summary of past treatment and tailored recommendations for Survivorship Care. The potential of the SurPass to improve person-centred Survivorship Care has been demonstrated previously [10,11]. The EU-funded PanCareSurPass project will develop an updated version (v2.0) of the SurPass allowing for semi-automated data entry and implement it in six European countries (Austria, Belgium, Germany, Italy, Lithuania and Spain), representative of three infrastructure healthcare scenarios typically found in Europe. The implementation study will investigate the impact on person-centred care, as well as costs and processes of scaling up the SurPass. Interoperability between electronic health record systems and SurPass v2.0 will be addressed using the Health Level Seven (HL7) International interoperability standards. PanCareSurPass will deliver an interoperable digital SurPass with comprehensive evidence on person-centred outcomes, technical feasibility and health economics impacts. An Implementation Toolkit will be developed and freely shared to promote and support the future implementation of SurPass across Europe. PanCareSurPass is a novel European collaboration that will improve person-centred Survivorship Care for CCS across Europe through a robust assessment of the implementation of SurPass v2.0 in different healthcare settings. • SurPass addressing knowledge gaps regarding Survivorship Care requirements. • SurPass v2.0 will improve person-centred Survivorship Care for CCS across Europe. • SurPass v2.0 as an interoperable digital tool. • Generating evidence on person-centred outcomes, feasibility and health economics. • Promoting uptake of the SurPass via freely available Implementation Toolkit.

Disparities in survival and long-term side-effects from paediatric cancer are observed across European Society for Paediatric Oncology (SIOPE)–affiliated countries. The Joint Action on Rare Cancers (JARC) is a project supported by the European Union and member states aiming to formulate recommendations on rare cancers, including paediatric malignancies, to reduce inequalities and to improve health outcomes. Most paediatric cancers are treated by a combination of systemic agents, surgery and/or radiotherapy. Radiotherapy for children is becoming increasingly complex because of the growing availability of new modalities and techniques and the evolution in molecular biology. These added challenges have the potential to enhance disparities in survival and side-effects between countries, but also among centres in the same country. To tackle radiotherapy-related inequalities, representatives of SIOPE, European SocieTy for Radiotherapy and Oncology, Paediatric Radiation Oncology Society and Childhood Cancer International–Europe defined 'standard' and 'optional' levels to deliver Good Clinical Practice–compliant treatment in paediatric radiation oncology with a focus on patient-related care, education and training. In addition, more than 250 paediatric radiotherapy centres across the SIOPE-affiliated countries have been mapped. For a better understanding of resources in paediatric radiotherapy, JARC representatives are working on an online survey for paediatric radiation oncologists of each centre in SIOPE-affiliated countries. The outcome of this survey will give an insight into the strengths and weaknesses of paediatric radiotherapy across SIOPE-affiliated countries and can be relevant for European Reference Networks in terms of collaboration pathways and referrals in paediatric radiotherapy. • Across European Society for Paediatric Oncology–affiliated countries, disparities in childhood cancer survival are a fact. • Radiotherapy for children is becoming increasingly complex. • The Joint Action on Rare Cancers aims to formulate appropriate recommendations to reduce inequalities. • Recommendations focus on patient care, education and training, and clinical research.

Abstract Background Currently, there are between 300,000 and 500,000 childhood cancer survivors (CCSs) in Europe. A significant proportion is at high risk, and at least 60% of them develop adverse health-related outcomes that can appear several years after treatment completion. Many survivors are unaware of their personal risk, and there seems to be a general lack of information among healthcare providers about pathophysiology and natural history of treatment-related complications. This can generate incorrect or delayed diagnosis and treatments. Method The Survivorship Passport (SurPass) consists of electronic documents, which summarise the clinical history of the childhood or adolescent cancer survivor. It was developed by paediatric oncologists of the PanCare and SIOPE networks and IT experts of Cineca, together with parents, patients, and survivors' organisations within the European Union–funded European Network for Cancer research in Children and Adolescents. It consists of a template of a web-based, simply written document, translatable in all European languages, to be given to each CCS. The SurPass provides a summary of each survivor's clinical history, with detailed information about the original cancer and of treatments received, together with personalised follow-up and screening recommendations based on guidelines published by the International Guidelines Harmonization Group and PanCareSurFup. Results The SurPass data schema contains a maximum of 168 variables and uses internationally approved nomenclature, except for radiotherapy fields, where a new classification was defined by radiotherapy experts. The survivor-specific screening recommendations are mainly based on treatment received and are automatically suggested, thanks to built-in algorithms. These may be adapted and further individualised by the treating physician in case of special disease and survivor circumstances. The SurPass was tested at the Istituto Giannina Gaslini, Italy, and received positive feedback. It is now being integrated at the institutional, regional and national level. Conclusions The SurPass is potentially an essential tool for improved and more harmonised follow-up of CCS. It also has the potential to be a useful tool for empowering CCSs to be responsible for their own well-being and preventing adverse events whenever possible. With sufficient commitment on the European level, this solution should increase the capacity to respond more effectively to the needs of European CCS. Highlights • Treatment summary and follow-up recommendations are available to CCSs via SurPass. • SurPass provides a homogeneous follow-up and screening for all European CCSs. • SurPass is a solution to organise long-term follow-up care in a consistent and cost-effective way. • The SurPass has the potential to be a useful tool for empowering CCSs.

Microbial induced concrete corrosion (MICC) is recognized as one of the main degradation mechanisms of subsurface infrastructure worldwide, raising the demand for sustainable construction materials in corrosive environments. This review aims to summarize the key research progress acquired during the last decade regarding the understanding of MICC reaction mechanisms and the development of durable materials from an interdisciplinary perspective. Special focus was laid on aspects governing concrete - micoorganisms interaction since being the central process steering biogenic acid corrosion. The insufficient knowledge regarding the latter is proposed as a central reason for insufficient progress in tailored material development for aggressive wastewater systems. To date no cement-based material exists, suitable to withstand the aggressive conditions related to MICC over its entire service life. Research is in particular needed on the impact of physiochemical material parameters on microbial community structure, growth characteristics and limitations within individual concrete speciation. Herein an interdisciplinary approach is presented by combining results from material sciences, microbiology, mineralogy and hydrochemistry to stimulate the development of novel and sustainable materials and mitigation strategies for MICC. For instance, the application of antibacteriostatic agents is introduced as an effective instrument to limit microbial growth on concrete surfaces in aggressive sewer environments. Additionally, geopolymer concretes are introduced as highly resistent in acid environments, thus representing a possible green alternative to conventional cement-based construction materials.

Adipose Triglyceride Lipase (ATGL) performs the first and rate-limiting step in lipolysis by hydrolyzing triacylglycerols stored in lipid droplets to diacylglycerols. By mediating lipolysis in adipose and non-adipose tissues, ATGL is a major regulator of overall energy metabolism and plasma lipid levels. Since chronically high levels of plasma lipids are linked to metabolic disorders including insulin resistance and type 2 diabetes, ATGL is an interesting therapeutic target. In the present study, fourteen closely related analogues of Atglistatin ( 1 ), a newly discovered ATGL inhibitor, were synthesized, and their ATGL inhibitory activity was evaluated. The effect of these analogues on lipolysis in 3T3-L1 adipocytes clearly shows that inhibition of the enzyme by Atglistatin ( 1 ) is due to the presence of the carbamate and N,N -dimethyl moieties on the biaryl central core at meta and para position, respectively. Mono carbamate-substituted analogue C2 , in which the carbamate group was in the meta position as in Atglistatin ( 1 ), showed slight inhibition. Low dipole moment of Atglistatin ( 1 ) compared to the synthesized analogues possibly explains the lower inhibitory activities. [ABSTRACT FROM AUTHOR]

Abstract: Despite the increase of cure rates in the treatment of children with cancer there is a significant discrepancy in the outcome within Europe. Data are showing us that there is a difference of 20% in outcomes for young people with cancer when comparing North and Western Europe with Central and Eastern Europe. One of the most important necessities, in order to be able to have comparable results and equitable outcomes about inequalities, is to have the Principle Treatment Centres, meeting a minimum level of standards and being accessible to continuously updated ‘best practice’. The European Society of Paediatric Oncology (SIOPE) has initiated a study in order to monitor the current situation of the European Standards of Paediatric Oncology Centres. The results of the study showed disparities of Standards of Care in the Treatment Centres across Europe. Therefore SIOPE initiated a project aimed at improving the Quality-of-Care of children and adolescents with cancer and to assess the relevant organisational aspects within paediatric oncology. At the first European Union (EU) Conference in Warsaw 2009, an agreement was obtained from all involved stakeholders to initiate the creation of Pan-European guidelines entitled ‘European Standards of Care for Children with Cancer’. The guidelines outlined in this document represent the minimum standards of care that should be implemented at the EU level. Describing the different aspects of Care over 15 chapters and available in more than 16 different EU languages these guidelines are used as tools for both professionals and parent/patients groups in order to advocate ‘improved standards across EU’.
