Intermedin(IMD) is a novel member of the calcitonin/calcitonin gene-related peptide (CT/CGRP) family that has anti-inflammatory, antioxidant and anti-apoptosis properties. https://www.selleckchem.com/products/dc661.html This study aimed to evaluate the renoprotective effects of IMD on podocyte apoptotic loss and slit diaphragm protein deficiency the kidneys of rats with in streptozotocin (STZ) induced diabetes in high glucose-exposed podocytes. Our results showed that IMD significantly attenuated proteinuria, and alleviated the abnormal alterations in glomerular ultrastructure in vivo. IMD also improved the induction of slit diaphragm proteins, and restored the decreased Bcl-2 expression and suppressed Bax and caspase-3 induction in the diabetic glomeruli. In addition, IMD attenuated podocyte apoptosis and filamentous actin (F-actin) rearrangement in high glucose-exposed podocytes. Exposure to high glucose elevated the unfolded protein response (UPR) to endoplasmic reticulum (ER) stress in renal podocytes, and IMD treatment blocked such ER stress responses pertinent to podocyte apoptosis and reduced synthesis of slit diaphragm proteins in vivo and in vitro. These observations demonstrate that targeting ER stress is an underlying mechanism of IMD-mediated amelioration of diabetes-associated podocyte injury and dysfunction.Despite advances in treatment of lethal prostate cancer, the incidence of prostate cancer brain metastases is increasing. In this sense, we analyzed the molecular profile, as well as the functional consequences involved in the reciprocal interactions between prostate tumor cells and human astrocytes. We observed that the DU145 cells, but not the LNCaP cells or the RWPE-1 cells, exhibited more pronounced, malignant and invasive phenotypes along their interactions with astrocytes. Moreover, global gene expression analysis revealed several genes that were differently expressed in our co-culture models with the overexpression of GLIPR1 and SPARC potentially representing a molecular signature associated with the invasion of central nervous system by prostate malignant cells. Further, these results were corroborated by immunohistochemistry and in silico analysis. Thus, we conjecture that the data here presented may increase the knowledge about the molecular mechanisms associated with the invasion of CNS by prostate malignant cells.

Changes in androgen dynamics within adipose tissue have been proposed as modulators of body fat accumulation. In this context, AKR1C2 likely plays a significant role by inactivating 5α-dihydrotestosterone.

To characterize AKR1C2 expression patterns across adipose depots and cell populations and to provide insight into the link with body fat distribution and genetic regulation.

We used RNA sequencing data from severely obese patients to assess patterns of AKR1C2 and AKR1C3 expression in abdominal adipose tissue depots and cell fractions. We additionally used data from 856 women to assess AKR1C2 heritability and to link its expression in adipose tissue with body fat distribution. Further, we used public resources to study AKR1C2 genetic regulation as well as reference epigenome data for regulatory element profiling and functional interpretation of genetic data.

We found that mature adipocytes and adipocyte-committed adipocyte progenitor cells (APCs) had enriched expression of AKR1C2. We found adipose ti in part mediate the effect of AKR1C2 expression on body fat distribution.

A recently identified population of T cells, phenotypically CD4

, has been firstly termed as peripheral helper T cells (Tph) and found to be pathogenic in autoimmune diseases. However, the potential role of Tph in ulcerative colitis (UC) remains unclear. We aim to investigate the changes of circulating Tph in UC patients and their potential significance in the pathogenesis of UC.

Totally 68 UC patients and 34 age- and sex-matched healthy controls were enrolled. Circulating Tph and B cell subsets were analyzed by flow cytometry. Expressions of inducible T-cell co-stimulator (ICOS) on Tph cells were analyzed. Serum IL-4, IL-10, IL-12 and IL-21 were detected using ELISA. Correlation analyses were conducted between Tph cells and disease severity, functional B cell subsets and serum cytokines.

Both the frequency and absolute number of Tph were significantly increased in active UC patients and ICOS levels in Tph cells were also elevated, compared with remission UC patients and healthy controls. Tph and ICOS expression were significantly positively correlated with Mayo score and serum CRP in active UC patients, and were significantly decreased when achieving remission after treatment. Tph levels were correlated with new memory B cells, plasmablasts, serum IL-4 and IL-21. Meanwhile, serum IL-10 showed negative correlation while IL-12 exhibited positive correlation with circulating Tph cells in UC patients.

Circulating Tph cells are elevated in active UC patients and are associated with the disease activity, which may contribute to the pathogenesis of UC.

Essentially, a new normative model of eating is now taking the place of the traditional models. The aims of this qualitative study were to explore what 'eating well', 'good food' and 'bad food' now mean in the New Caledonian family context and, more broadly, to categorise the current food practices and representations in adolescents' families. A double qualitative methodology was applied 59 face-to-face interviews with 30 parents and 29 adolescents in both rural and urban areas and 15 collective structured discussions with middle-school classes (11- to 16-year-olds) of almost 25 students each. The main results showed various normative frames for nutrition, food quantities, local provenance, and personal taste. Food practices were related to food availability (having a home garden or involvement in family farming), socioeconomic status and community. In addition, access to nutritional information, temporal and financial constraints mostly in the urban area, and the role of food socialisation between parents and children had an impact on food practices and perceptions. The permanence of food cultures, mainly observed in families in rural areas, and the social inequalities in urban areas regarding food availability are highlighted. The positive perception of 'local food' as 'cultural', 'organic' and 'healthy' may help policymakers communicate clear messages to reach a sustainable food system.The objective of this study was to compare the relationships between food parenting practices and child eating behavior among mothers and fathers of young children. This cross-sectional study recruited mothers (n = 127) and fathers (n = 118) of children (4.2 ± 1.3 years old) to complete surveys (face-to-face and online). Each parent completed the Comprehensive Food Parenting Questionnaire, Children's Eating Behavior Questionnaire, and demographic questions. Linear regressions were used to compare the relationships between parental food parenting practices and children's eating behaviors with parent sex as a moderator. Child age and sex served as control variables in each regression. Parent sex was a significant moderator in several relationships between parent food parenting practices and child eating behavior. In the relationship between parental restriction for health (ß = -.14, p = .014) and monitoring (ß = -.13, p = .028) and child slowness in eating, the slope of the interaction was significantly higher for mothers, meaning that when mothers and fathers use the same level of restriction for health and monitoring, child slowness in eating is higher for children of mothers. When mothers and fathers used the same level of restriction for weight, child food responsiveness (ß = .13, p = .003) and emotional overeating (ß = .12, p = .046) was significantly higher for children of fathers. There may be differences in how mothers and fathers implement food parenting practices and/or differences in how these practices impact children. Specifically, for fathers, it seems that the use of restriction for weight is more detrimental for children's eating behaviors compared to when mothers use the same level of restriction for weight.Polybrominated diphenyl ethers (PBDEs) are persistent organic pollutants (POPs). They are constantly detected in foods. PBDEs can disrupt the intestinal flora, but enterotoxicity is unknown. Luteolin, one kind of flavonoid, has drawn increasing interest as an agent that strengthens the intestinal barrier. This study aimed to evaluate the mitigating effect of luteolin on damage to the intestinal barrier induced by decabromodiphenyl ether (BDE-209) in a Caco-2 cell monolayer model. Results showed that luteolin mitigated BDE-209-induced damage to intestinal epithelial barrier by reducing the levels of reactive oxygen species (ROS), increasing the activity of superoxide dismutase (SOD) and glutathione (GSH), suppressed the secretion of pro-inflammatory cytokines (TNF-α, IL-6, and IL-1β), and increased the expression of tight junction (TJ) proteins (ZO-1, occludin, and claudin-1). Furthermore, the protective effects were related to the inhibition of extracellular regulated protein kinases (ERK) and nuclear factor kappa-B (NF-κB)/myosin light chain kinase (MLCK) signaling pathways, and the activation of nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathways. This study is the first to provide strong evidence that BDE-209 can damage the intestinal barrier, and we here investigated the important protective effect of luteolin, which may lay the foundation for the development of luteolin as a dietary supplement to strengthen the intestinal barrier.There is increasing knowledge regarding the role of the microbiome in modulating the brain and behaviour. Indeed, the actions of microbial metabolites are key for appropriate gut-brain communication in humans. Among these metabolites, short-chain fatty acids, tryptophan, and bile acid metabolites/pathways show strong preclinical evidence for involvement in various aspects of brain function and behaviour. With the identification of neuroactive gut-brain modules, new predictive tools can be applied to existing datasets. We identified 278 studies relating to the human microbiota-gut-brain axis which included sequencing data. This spanned across psychiatric and neurological disorders with a small number also focused on normal behavioural development. With a consistent bioinformatics pipeline, thirty-five of these datasets were reanalysed from publicly available raw sequencing files and the remainder summarised and collated. Among the reanalysed studies, we uncovered evidence of disease-related alterations in microbial metabolic pathways in Alzheimer's Disease, schizophrenia, anxiety and depression. Amongst studies that could not be reanalysed, many sequencing and technical limitations hindered the discovery of specific biomarkers of microbes or metabolites conserved across studies. Future studies are warranted to confirm our findings. We also propose guidelines for future human microbiome analysis to increase reproducibility and consistency within the field.
