Abstract
© 2016 Elsevier Inc. Tumor cells are often exposed to intrinsic and external factors that alter protein homeostasis, thus producing endoplasmic reticulum (ER) stress. To cope with this, cells evoke an adaptive mechanism to restore ER proteostasis known as the unfolded protein response (UPR). The three main UPR signaling branches initiated by IRE1α, PERK, and ATF6 are crucial for tumor growth and aggressiveness as well as for microenvironment remodeling or resistance to treatment. We provide a comprehensive overview of the contribution of the UPR to cancer biology and the acquisition of malignant characteristics, thus highlighting novel aspects including inflammation, invasion and metastasis, genome instability, resistance to chemo/radiotherapy, and angiogenesis. The therapeutic potential of targeting ER stress signaling in cancer is also discussed. Trends Highly proliferative tumors are exposed to several intrinsic and extrinsic factors that induce adaptation to stress conditions. ER s
