Kidney response to hypoxia
WebGenetic induction of hypoxia signaling by deletion of the von Hippel-Lindau (Vhl) protein in mesenchymal PDGFR-β+ cells leads to abundant HIF-2 dependent erythropoietin (EPO) expression in the cortex and outer medulla of the kidney. This rather unique feature of kidney PDGFR-β+ cells promote questions about their special characteristics and … WebHypoxia resulted in an 85% reduction in glomerular filtration rate (GFR) without any change in total renal vascular resistance. There was an initial 85% increase in urine flow rate …
