Q: A study by Trune and Kempton linked this hormone and prednisolone to autoimmune hearing loss. Spironolactone and eplerenone antagonize receptors for this hormone, and the Captopril suppression test involves muting this hormone's production to investigate its hyperactivation. This hormone is oversecreted in a form of hypertension called Conn's Syndrome, and both this and cortisol are deficient in Addison's disease. By inducing angiotensin secretion, renin indirectly promotes this hormone's release from the zona glomerulosa in a certain feedback system. Its primary purpose is to stimulate ion pumps. For 10 points, name this hormone secreted from the adrenal cortex which promotes the reabsorption of sodium and water in the kidneys.
