Project description:Kidney structural integrity is critical for bodily excretory mechanism. Diabetes has been considered as one of the major risk factors for chronic kidney disease, but the underlying mechanism remains elusive. The present study investigates the transcriptomic and proteomic profiling of long-term impact of high-fat diet (HFD) on renal tissue in mice and role of dehydrozingerone (DH) in reinstating the normal kidney function. Animals were divided into four groups- healthy (NCD+Veh), diabetic (HFD-STZ+Veh), healthy+DH (NCD+Veh+DH) and treatment (HFD-STZ+DH). 65th days of HFD-fed C57BL/6 mice developed diabetes and kidney dysfunction evident by albuminuria, proteinuria, and glucotoxicity with accumulation of glucose, triglyceride, cholesterol, albumin, and total protein in blood serum. The HFD-fed kidney showed renal injuries, including prominent defects in the glomerular filtration system by downregulation of proteins involved in transport, metabolic process, energy production, anti-oxidation, etc. Downregulation of lipid metabolism is the most impacted metabolic process under diabetic condition. Downregulation of transport proteins mainly impact the functioning of podocytes, cell adhesion and cytoskeletal rearrangement. HFD feeding also increased oxidative stress and induced mitochondrial dysfunction, and thereby activating the pro-apoptotic pathway. Progression of DNA damage under diabetic condition triggered the epigenetic alteration and subsequent downstream changes which is evident by activation of HDAC1 under diseased condition. Transcriptomic study revealed the potential of dehydrozingerone in attenuating the diabetic condition by positively regulating transport system, mitochondrial function, lipid metabolism, DNA damage and epigenetic alteration, and oxidative stress, which ameliorate the kidney function.
Project description:The aim of this study is to compare renal transcriptome profiling between diabetic nephropathy (DN) and DN treated with human placenta-derived mesenchymal stem cells (PMSCs) groups. Twelve renal cortex samples (n=6 for each DN and treatment group) were sequenced using Illumina Hiseq 4000. We identified 90 differentially expressed genes between DN and treatment griups with |og2 FoldChange| ≥1 and p value <0.05. Our study represents the first detailed analysis of renal transcriptomes, with biologic replicates, generated by RNA-seq technology.
Project description:In order to more accurately and objectively clarify the biological role of lncRNAs in diabetic nephropathy, we detected their expression profiles in renal tissues from patients with diabetic nephropathy.

Project description:Transcriptional profiling of human PBMCs comparing healthy controls, patients with diabetic nephropathy and patients with ESRD. PBMCs were analyzed as they mediate inflammatory injury. Goal was to determine effects of increasing severity of diabetic nephropathy on global PBMC gene expression. Microarray analysis of PBMCs taken from patients with varying degrees of diabetic nephropathy.
Project description:Diabetic nephropathy and diabetic retinopathy are related. We used scRNA-seq and RNA-seq to analyze the cellular linkage between them.
