Calcitriol ameliorates renal injury with high-salt diet-induced hypertension by upregulating GLIS2 expression and AMPK/mTOR-regulated autophagy
Gene. 2022 Jan 31:146239. doi: 10.1016/j.gene.2022.146239. Online ahead of print.ABSTRACTThe goal of the present study was to investigate the protective effect of calcitriol on high-salt diet-induced hypertension. The hypertension rat model was established by a long-term high-salt diet (8% NaCl). Rats were treated with calcitriol, losartan, or their combination. Histological staining was used to confirm renal pathology. Global transcriptome analysis of renal tissues was performed, and the mechanism of the therapeutic effect of calcitriol was analysed by functional annotation and pathway analysis of the differentially expre...

Abstract P180: Dopamine D2 Receptors Regulate Wnt Signaling and Apoptosis in Human Renal Proximal Tubule Cells Session Title: Genetics, Epigenetics, Proteomics and Metabolomics
Previous work from our laboratory indicates that the dopamine D2 receptor (D2R) in the kidney has a direct role in regulating renal inflammation and injury and blood pressure. Some common single nucleotide polymorphisms (D2R SNPs; rs 6276, 6277, and 1800497) in the human DRD2 gene are associated with decreased D2R expression and function. Immortalized renal proximal tubule cells (RPTCs) from subjects carrying D2R SNPs (RPTC-D2R SNPs) express less D2Rs than RPTCs carrying no D2R SNPs (RPTC-D2R WT) (62±4 vs 100±6%; P<0.04) and a pro-inflammatory and pro-fibrotic phenotype with markers of epithelial mesenchym...

Abstract 191: Transcriptional Regulation of Renin by Nuclear Receptors Co-regulated With Renin Poster Session I
Expression of the renin gene is required to maintain normal morphological and physiological identity of renal juxtaglomerular (JG) cells, yet the mechanisms regulating renin gene transcription remain elusive. We re-examined data from Brunskill et. al (JASN 22:2213, 2011), investigating genome-wide gene expression in JG and other renal cell types. Based on our previous data implicating nuclear receptors (RAR, RXR, VDR, PPARG, Nr2f2 and Nr2f6) in the regulation of mouse and human renin gene expression, we focused our analysis on the expression of genes encoding the 48 nuclear hormone receptors and their co-regulation with re...
