ATG7 and pancreatic ductal adenocarcinoma: In pancreatic ductal adenocarcinoma (PDAC), enhanced expression of PD-1 was seen in peripheral CD8+ T cells, while in bladder cancer it has been reported that autophagy related 7 (ATG7) protein regulates the expression of PD-L1 protein and overexpression of ATG7 results in increased PD-L1 protein levels by stimulating autophagy-dependent degradation of FOXO3A.
