In diabetic nephropathy, DPPA acts as an important drug to treat renal interstitial fibrosis by activating AKT signalling.10 Recently, DPPA was shown to increase Bcl‐2 expression in Hela cells.8 That report suggests that DPPA may exert an anti‐apoptotic effect and promotes tumourigenesis in cervical adenocarcinoma. This evidence concerns the gene AKT1 and diabetic kidney disease.
