Project description:Renal failure is associated with accumulation of various solutes called Uremic toxins. Post transcriptional regulation related to Chronic kidney disease (CKD) have already been described as RNA based silencing with micro RNA or modifications of mRNA degradation. Until now, alternative splice modification was not mentioned in the course of CKD. However, CKD is associated with modification of gene expression. The aim of the study was to explore modification of the alternative splice pattern in the course in CKD. The expression level of individual exons expression in human fibroblast were compared after culture to 96 hours of uremic condition or control condition. Three independant experiments were performed

Project description:Transcriptome analysis of human coronary arterial endothelial cells (HCAEC) primary cultures exposed to uremic serum from patients with stage 4-5 cardiovascular diseases (CKD) without myocardial infarction (USI) and stage 4-5 CKD with myocardial infarction (UCI). Gene expression profile of human coronary arterial endothelial cells (HCAEC) primary cultures exposed to uremic serum from of patients with chronic kidney disease (CKD) that explore which pathways are involved in in the development of cardiovascular disease. The metabolic pathway significantly represented was the MAPK signaling pathway, suggesting that the effects of uremic toxins present in patients with CDK, on the primary cultures of HCAEC provides a more informative model for the study of molecular mechanisms that lead to the development of endothelial dysfunction secondary to CKD.

Project description:Background. Chronic renal failure is characterized by progressive renal scarring and accelerated cardiovascular disease. In animal models, this is thought to be due to non-dialyzable uremic toxins – small, protein-bound molecules normally secreted via Organic Anion Transporters (OATs) in the proximal renal tubule,rather than filtered at the glomerulus. The best studied of these is indoxyl sulfate (IS). Methods. We examined global gene expression responses in cultured normal human renal tubular cells incubated with control plasma (n=5) or pre- and post-dialysis uremic plasma (n=10). Results. GeneSpring analysis of microarrays revealed significantly altered expression of 2016 genes. The expression of 537 genes “normalized” in post-dialysis plasma, suggesting removal of “low molecular weight uremic toxins” by dialysis. The expression of the majority of dysregulated genes (1479) was not normalized in post-dialysis plasma. These likely represent the effects of substances not effectively removed by dialysis (“protein-bound uremic toxins”). Addition of indoxyl sulfateto control plasma simulated most effects (81.1%) of uremic plasma, while the addition of probenecid, an OAT inhibitor, to uremic plasma reversed most changes in gene expression. Analysis of molecular programs with the Gene Set Enrichment Analysis and the DAVID database revealed patterns common to indoxyl sulfate-treated control plasma, pre-dialysis, and post-dialysis uremic plasma. These included increased cell cycle, pro-inflammatory, and pro-fibrotic molecular programs, particularly genes in the TGF-β pathway. Conclusion: These findings provide insight into the role of non-dialyzable, protein-bound uremic toxins in the pathogenesis of renal scarring and uremic vasculopathy. The GSEA patterns confirm that inflammatory and fibrotic programs are active.

Project description:Uremic pruritus (UP) is one of the common symptoms in patients with uremia, and its etiology and mechanism have not been fully understood. In view of the high incidence of UP, finding the specific changed proteins in blood of UP patients will help revealing the potential biological mechanisms of UP and explore biomarkers. In this study, LC-MS/MS based data independent acquisition (DIA) mode was used to analyze the serum samples of 54 UP patients (DKD-UP, HN-UP and GN-UP, n=18 for each), 18 uremic patients without pruritus (Negative) and 18 CKD patients without pruritus (CKD).

Project description:End-stage renal disease (ESRD) is the final stage of chronic kidney disease, which is increasingly prevalent worldwide and is associated with the progression of cardiovascular disease (CVD). Indoxyl sulfate (IS) and p-cresyl sulfate (PCS), major uremic toxins, are major risk factors involved in the pathology of CVD via adverse effects on endothelial cells and immune cells. Thus, transcriptomic overview of uremic toxin-mediated genes in immune cells of ESRD patients is critical, but not yet fully known. We investigated the alteration of gene expressions and biological pathways mediated by major uremic toxins, in ESRD patients monocytes, via microarray analysis. To explore uremic toxin-related transcriptional profiling in ESRD patient-derived monocytes, purified monocytes from healthy controls were treated with IS or PCS for 24 hr, followed by conducting microarray on these samples.

Project description:Cardiovascular disease (CVD) is exceedingly severe in patients with chronic kidney disease (CKD) and further aggravated by peritoneal dialysis (PD), exposing the patients to excessive amounts of intraperitoneal glucose. Children are devoid of pre-existing CVD and give insight into specific uremia and PD induced pathomechanisms. Fat surrounded omental arterioles beyond PD fluid penetration level were microdissected from uremic children at time of first PD catheter insertion (n=8), children on PD (n=5), and age and gender matched non-uremic children as controls (n=6). Adjacent sections of 4 arterioles per patient were used for transcriptomic analyses.
