Abstract :
Pancreatic cancer is a highly aggressive and chemotherapy-resistant malignant neoplasm. In basal condition, it is characterized by elevated autophagy activity, which is required for tumor growth and that correlates with treatment failure. We analyzed the expression of autophagy related genes in different pancreatic cancer cell lines. A correlation-based network analysis evidenced the sociality and topological roles of the autophagy-related genes after serum starvation. Structural and functional tests identified a core set of autophagy related genes, suggesting different scenarios of autophagic responses to starvation, which may be responsible for the clinical variations associated with pancreatic cancer pathogenesis.
