Transcriptional profiling of autophagy proficient and compromised cell lines, determined by expression levels of Atg5

ABSTRACT: Autophagy is activated in pancreatic ductal adenocarcinoma (PDAC) and is currently being considered a promising therapeutic target in clinical trials. PDAC is a highly lethal disease with incidence rate equalling mortality rate. Main reasons for PDAC lethality are late-stage diagnosis, high agressiveness and metastatic rate, lack of effective treatments as well as specific diagnostic markers. Here we show that varying levels of the Autophagy related gene 5 (Atg5) determine pancreatic tumor formation and malignancy. While homozygous deletion of Atg5 blocks tumor progression in an in vivo model of PDAC, heterozygous deletion increases tumor aggressiveness and metastasis. Further analyses reveal that monoallelic loss of Atg5 affects mitochondrial homeostasis, changes intracellular calcium osc
