BECN1 and pancreatic ductal adenocarcinoma: Another study by Ko et al. [86] presented an evaluation of the expression of five autophagy-related proteins—LC3B, ATG5, Beclin 1 and its two cofactors, AMBRA1 (activating molecule in beclin-1-regulated autophagy) and Bif-1 (Bax-interacting factor 1)—in the resected pancreatic ductal adenocarcinoma tissues from a relatively small cohort of 73 patients.
