Kidney response to hypoxia

WebThese and other biologically important genes have in common either promoter or enhancer elements that respond to hypoxia. Among these, the erythropoietin gene has the most robust response to hypoxia . Erythropoietin acts via a classic physiological feedback loop. It is made primarily in the kidney, in particular in response to hypoxic stress. Web13 mrt. 2024 · When the body is exposed to hypoxia or undergoes hypoxic conditions, HIF-2α regulates EPO expression in combination with hypoxia response elements on the EPO gene in the kidney and liver. 45, 46 Currently, targeting HIF has been effective and well tolerated for the correction of anaemia with CKD, as evidenced from pooled phase 3 …

WebBackground. Using the renal clearance of lithium as an index of proximal tubular outflow, this study tested the hypothesis that acute hypocapnic hypoxemia decreases proximal tubular reabsorption to the same extent as hypocapnic normoxemia (hyperventilation) and that this response is blunted during normocapnic hypoxemia.Methods. Eight persons … WebIn reaction to acute hypoxia, vasopressin, a potent antidiuretic hormone involved in salt and water balance, is produced. Vasopressin acts by stimulating the renal retention of water, which increases blood volume and pressure and promotes the excretion of sodium and chloride via the kidneys.
