Pancreatic ductal adenocarcinoma (PDAC) is one of the few cancer types where the
5-year survival rate shows no improvement. Despite conflicting evidence, the
majority of data points to an essential role for autophagy in PDAC growth and
survival, in particular constitutively activated autophagy, can provide crucial
fuel to PDAC tumor cells in their nutrient-deprived environment. Autophagy, which
is required for cell homeostasis, can both suppress and promote tumorigenesis and
tumor survival in a context-dependent manner. Protein by protein, the mystery of
how PDAC abuses the cell's homeostasis system for its malignant growth has
recently begun to be unraveled. In this review, we focus on how autophagy is
responsible for growth and development of PDAC tumors and where autophagy and the
mechanisms controlling it fit into PDAC metabolism. Understanding the range of
pathways controlling autophagy and their interplay in PDAC could open the way for
new therapeutic avenues.
