Loss of DEPTOR in renal tubules protects against cisplatin-induced acute kidney injury.

ABSTRACT: DEP domain containing mTOR-interacting protein (DEPTOR) was originally identified as an in vivo dual inhibitor of mechanistic target of rapamycin (mTOR). It was recently reported to be involved in renal physiology and pathology in vitro; however, its detailed roles and mechanisms in vivo are completely unknown. We observed that DEPTOR expression in the kidney was markedly increased on day 3 after cisplatin treatment, at which time cell apoptosis peaked, implicating DEPTOR in cisplatin-induced acute kidney injury (AKI). We then used the Cre-LoxP system to generate mutant mice in which the DEPTOR gene was specifically deleted in the proximal tubule cells. DEPTOR deficiency did not alter the renal histology or functions in the saline-treated group, indicating that DEPTOR is not essential for
