Hif1alpha is a key regulator of cellular adaptation and survival under hypoxia. We generated murine PDAC cells with Hif1alpha shRNA to downregulate Hif1alpha expression. The Hif1alpha depletion results in rapid tumour growth with marked hypoxia-induced cell death, which leads to a persistent tumour-sustaining inflammatory response. However, it simultaneously reduces tumour colonisation and hepatic metastases by increasing the susceptibility to anoikis induced by anchorage-independent conditions. Taken together, the role of Hif1alpha in pancreatic tumorigenesis is context-dependent.
