POU class 1 homeobox 1 (POU1F1; PIT1)

Cell culture and mouse studies suggest spironolactone could help prevent calcification of vascular and other soft tissues, which is seen in patients who have chronic kidney disease (CKD). In a mouse model of soft tissue calcification, spironolactone decreased tissue calcification and Pit1-mediated osteoinductive signaling compared with vehicle. In human aortic smooth muscle cells, spironolactone and PIT1-targeted small interfering RNA both decreased PIT1-mediated osteoinductive signaling compared with vehicle or control siRNA. Next steps include a prospective clinical trial to determine whether patients with CKD receiving spironolactone or another mineralocorticoid receptor antagonist have less tissue calcification and fewer cardiovascular complications than placebo-treated patients.
Spironolactone is a generic mineralocorticoid receptor antagonist and is used as a diuretic in patients who have cardiovascular diseases.
