GPR124 Protects against Podocyte Senescence and Injury in Diabetic Kidney Disease

ABSTRACT: Cellular senescence is associated with the progression of diabetic kidney disease (DKD), and accelerated podocyte senescence promotes the pathogenesis of renal damage. We found that GPR124 was reduced in cultured human podocytes treated with high glucose (HG).To further clarify the role of GPR124 in podocytes, we overexpressed GPR124 via plasmid-harboring adenovirus infection. By RNA sequencing analysis of podocytes with different treatment, we observed GPR124 overexpression significantly affected several kinds of cell adhesion.

Increased long noncoding RNA maternally expressed gene 3 contributes to podocyte injury induced by high glucose through regulation of mitochondrial fission

Project description:Excessive mitochondrial fission plays a key role in podocyte injury in diabetic kidney disease (DKD), and long noncoding RNAs (lncRNAs) are important in the development and progression of DKD. However, lncRNA regulation of mitochondrial fission in podocytes is poorly understood. Here, we want to identify how lncRNA changes in human podocytes cultured with high glucose.

Glomerular RNA-seq data of the kidney podocyte-specific Hdac1 and Hdac2 deficient mice

Project description:Podocyte histone deacetylases (HDAC) are essential in maintaining a normal glomerular filtration barrier by modulating podocyte quiescence. Podocyte-specific loss Hdac1 and 2 in mice results in severe proteinuria and sustained DNA damage, likely caused by epigenetic alterations and deficient DNA repair, that result in podocyte senescence. Through glomeruli isolation and RNA-seq profiling from the mutant mice, we demonstrated that senescent podocytes develop a senescence-associated secretory phenotype (SASP) that contribute to the loss of podocytes. The role of HDACs in senescence may provide important clues in our understanding of how podocytes are lost following injury.

Podocyte-specific JAK2 Overexpression Worsens Diabetic Kidney Disease in Mice

Project description:Overexpression of glomerular JAK2 mRNA specifically in glomerular podocytes of 129S6 mice led to significant increases in albuminuria, mesangial expansion, glomerulosclerosis, glomerular fibronectin accumulation, and glomerular basement membrane thickening as well as a significant reduction in podocyte density in diabetic mice. Treatment with a specific JAK1/2 inhibitor partly reversed the major phenotypic changes of DKD

Elevation of JAML Promotes Diabetic Kidney Disease by Modulating Podocyte Lipid Metabolism

Project description:Podocytes, highly differentiated glomerular epithelial cells, are essential for the maintenance of glomerular filtration barrier. Lipid accumulation in podocytes is a major determinant of proteinuric kidney disease. By RNA-sequencing analysis, we observed the significant changes of genes important in regulating cellular lipid homeostasis in podocytes with HG treatment. We generated two mouse podocyte cell lines stably transduced with either a sh-NC lentiviral construct or a shRNA lentiviral construct designed to target JAML RNA to investigate the consequences on the gene expression profile of JAML knockdown in mouse podocytes.

Expression data for OVE26 diabetic mouse podocyte

Project description:Podocytes form filtration barrier through foot process around glomerualar basement membrane and selectively permit permeability of molecular smaller than albumin. Diabetes can cause podocyte pathological changes leading to high urine albumin level. Diabetic mouse model OVE26 has extremly high urine albumin and previously studies indicated its podocyte damaged. Here we try to find the key genes change in OVE26 diabetic mouse model podocyte by microarray assay while normal FVB mouse podocyte set as control. Podocyte eGFP transgenic mice were made on FVB background and crossbred to OVE26 diabetic model. Glomeruli isolated from OVE-GFP mice were digested by trypsin into signal cell. Podocytes with GFP were sorting out by FACS.

Glomerular podocyte RNA-seq data of the podocyte-specific Profilin1 deficient mice

Project description:The progression of proteinuric kidney disease is associated with podocyte loss but the mechanisms remain unclear. Podocytes reenter the cell cycle to repair damaged ds DNA breaks. However, unsuccessful repair results in podocytes crossing the G1/S checkpoint and undergoes abortive cytokinesis. In this study, we identified Pfn1 as a major contributor in maintaining glomerular integrity and its loss in mice results in severe proteinuria, and kidney failure due to podocyte mitotic catastrophe, characterized by abundant multinucleated cells. Reentry of podocytes were identified by using FUCCI-2aR mice, accompanying the alteration of cell-cycle associated proteins, such as P21, P53, Cyclin B, and Cyclin D. Podocyte-specific translating ribosome affinity purification (TRAP) and RNAseq revealed a reduction of Ribosomal RNA-processing protein 8 (Rrp8) and re-expression of Rrp8 partially rescued the in-vitro phenotype. Clinical analysis of patients with proteinuric kidney disease demonstrated multinucleated podocytes and reduced podocyte profilin1 in kidney tissue. These results suggest that profilin is indispensible in regulating podocyte cell cycle and its disruption contributes to podocyte loss through mitotic catastrophe.

OASIS overexpression in murine podocyte cell line

Project description:Podocyte injury is involved in the onset and progression of various kidney diseases. We previously demonstrated that the transcription factor, old astrocyte specifically induced substance (OASIS) in myofibroblasts, contributes to kidney fibrosis, as a novel role of OASIS in the kidneys. Importantly, we found that OASIS is also expressed in podocytes; however, the pathophysiological significance of OASIS in podocytes remains unknown. Upon lipopolysaccharide (LPS) treatment, there is an increase in OASIS in murine podocytes. Enhanced serum creatinine levels and tubular injury, but not albuminuria and podocyte injury, are attenuated upon podocyte-restricted OASIS knockout in LPS-treated mice, as well as diabetic mice. The protective effects of podocyte-specific OASIS deficiency on tubular injury are mediated by protein kinase C iota (PRKCI/PKCι), which is negatively regulated by OASIS in podocytes. Furthermore, podocyte-restricted OASIS transgenic mice show tubular injury and tubulointerstitial fibrosis, with severe albuminuria and podocyte degeneration. Finally, there is an increase in OASIS-positive podocytes in the glomeruli of patients with minimal change nephrotic syndrome and diabetic nephropathy. Taken together, OASIS in podocytes contributes to podocyte and/or tubular injury, in part through decreased PRKCI. The induction of OASIS in podocytes is a critical event for the disturbance of kidney homeostasis.

Gene expression in a conditionally immortalized mouse podocyte cell line

Project description:The specialized glomerular epithelial cell (podocyte) of the kidney is a complex cell that is often damaged in glomerular diseases. Study of this cell type is facilitated by an in vitro system of propagation of conditionally immortalized podocytes. Here, genes that are differentially expressed in this in vitro model of podocyte differentiation are evaluated. Conditionally immortalized undifferentiated mouse podocytes were cultured under permissive conditions at 33*C. Podocytes that were differentiated at the non-permissive conditions at 37*C were used for comparison.

Comparison of Glomerular and Podocyte mRNA Profiles in eNOS-/- Diabetic Mice Induced by Streptozotocin

Project description:We compared mRNA profiles of isolated glomeruli versus sorted podocytes between diabetic and control mice. IRG mice crossed with eNOS-/- mice were further bred with podocin-rTTA and TetON-Cre mice to permanently label podocytes before the diabetic injury. Diabetes was induced by injection of streptozotocin. mRNA profiles of isolated glomeruli and sorted podocytes from diabetic and control mice at 10 weeks after induction of diabetes were examined. Consistent with the previous reports, expression of podocyte-specific markers in the glomeruli were down-regulated in the diabetic mice compared to controls. However, these differences disappeared when mRNA levels were corrected for podocyte number per glomerulus. Interestingly, the expression of these markers was not altered in sorted podocytes from diabetic mice, suggesting that the reduced expression of podocyte markers in isolated glomeruli is likely a secondary effect of reduced podocyte number, rather than the loss of differentiation markers. Analysis of the differentially expressed genes in diabetic mice also revealed distinct up-regulated pathways in the glomeruli (mitochondrial function and oxidative stress) and podocytes (actin organization). In conclusion, our data suggest that podocyte-specific gene expression in transcriptome obtained from the whole glomeruli may not represent those of podocytes in the diabetic kidney. We compared mRNA profiles of isolated glomeruli versus sorted podocytes between diabetic and control mice.
