Project description:To clarify the molecular mechanism of inflammatory control in diabetic-derived neutrophils, we screened for changes of circRNA expression in diabetic-derived neutrophils using microarrays.
Project description:We investigated the gene expression profiles of RNA isolated from kidney glomeruli from aged, 25 week old type-2 diabetic (db/db) and non-diabetic mice.
Project description:We investigated the gene expression profiles of RNA isolated from kidney glomeruli from aged, 25 week old type-2 diabetic (db/db) and non-diabetic mice. In order to investigate the consequences of hyperglycemia on the pathogenesis and progression of diabetic nephropathy Kidney glomeruli from 3 diabetic and 3 non-diabetic, control mice were isolated and RNA purified for RNA-Seq analysis on the Illumina HiSeq 2000. The goal of the project was to generate comprehensive list of noncoding RNA genes differentially regulated between the two conditions in order to identify novel targets for further study.
Project description:Diabetic nephropathy(DN) is a common diabetic microvascular complication, the underlying mechanisms involved in DN remain to be elucidated. We used microarrays to explore the global profile of gene expression for better understanding the molecular mechanism of diabetic nephropathy in type 2 diabetic db/db mice.
Project description:More and more studies pointed out that BM was the primary target of diabetes mellitus-induced damage. The aim of this study was to determine whether distinct gene expression profiles are associated with altered functions of bone marrow cells in diabetes mellitus type 2 mice. We performed global gene expression analysis in the bone marrow cells of 3 diabetic mice and 3 non-diabetic mice using Affymetrix Gene Chip Mouse Gene 1.0 ST Arrays. The gene expression patterns of diabetic mice were compared with those of nondiabetic ones using fold change. Validity of microarray results was examined by quantitative RT-PCR.
Project description:We investigated the gene expression profiles of RNA isolated from kidney glomeruli and renal tubules from aged, 24 week old type-2 diabetic (db/db) and non-diabetic mice
Project description:Cognitive dysfunction is the main feature of diabetic encephalopathy (DE). The effect and mechanism of trichostatin A (TSA) on cognitive function of diabetic mice is not elucidated. Our study revealed the key pathways and vital hubgenes of the effect of TSA on hippocampus of type II diabetic mice, including longevity regulating pathway, peroxisome, ribosome, protein processing in endoplasmic reticulum, insulin signaling pathway, CAT and PRKAA2. As well, GSK-1059615, alisertib and avrainvillamide-analog-6 were suggested to be the promising ancillary intervention drugs for diabetic encephalopathy.
Project description:Diabetic kidney disease (DKD) is the leading cause of end-stage renal disease. Neutrophil extracellular traps (NETs) are a network structure composed of loose chromatin and embedded with multiple proteins. Here, we observed increased NETs deposition in the glomeruli of DKD patients and diabetic mice (streptozotocin-induced or db/db mice). After degrading NETs with DNase I, diabetic mice exhibited attenuated glomerulopathy and glomerular endothelial cell (GEC) injury. We also observed alleviated glomerulopathy and GEC injury in peptidylarginine deiminase 4 (PAD4)-knockout mice with streptozotocin-induced diabetes. In vitro, NET-induced GEC pyroptosis was characterized by pore formation in the cell membrane, dysregulation of multiple genes involved in cell membrane function, and high expression of pyroptosis-related proteins. Strengthening the GEC surface charge by oleylamine significantly inhibited NET-induced GEC pyroptosis. These results indicate that NET-induced alterations in GEC charge are associated with GEC pyroptosis in the pathogenesis of DKD and suggest that NETs are a potential therapeutic target for DKD.
Project description:Diabetes is associated with an increase in neutrophil NET production. Low density neutrophils (LDNs) have a greater propensity for spontaneous production of NETs, and are increased in the diabetic host during infection with S. aureus. We compared gene expression between high density (HDN) and LDNs isolated from the blood of infected db/db mice.
