Cancer Microenvironment and Endoplasmic Reticulum Stress Response
Different stressful conditions such as hypoxia, nutrient deprivation, pH changes, or reduced vascularization, potentially able to act as growth-limiting factors for tumor cells, activate the unfolded protein response (UPR). UPR is therefore involved in tumor growth and adaptation to severe environments and is generally cytoprotective in cancer. The present review describes the molecular mechani...
متن کاملEndoplasmic Reticulum Stress and Cancer
The endoplasmic reticulum (ER) is the principal organelle responsible for multiple cellular functions including protein folding and maturation and the maintenance of cellular homeostasis. ER stress is activated by a variety of factors and triggers the unfolded protein response (UPR), which restores homeostasis or activates cell death. Multiple studies have clarified the link between ER stress a...
متن کاملEndoplasmic Reticulum Stress, Unfolded Protein Response, and Cancer Cell Fate
Perturbation of endoplasmic reticulum (ER) homeostasis results in a stress condition termed "ER stress" determining the activation of a finely regulated program defined as unfolded protein response (UPR) and whose primary aim is to restore this organelle's physiological activity. Several physiological and pathological stimuli deregulate normal ER activity causing UPR activation, such as hypoxia...
متن کاملEndoplasmic reticulum stress response and transcriptional reprogramming
Endoplasmic reticulum (ER) is an intracellular organelle responsible for protein folding and assembly, lipid and sterol biosynthesis, and calcium storage. As a protein folding compartment, the ER provides a high-fidelity quality control system to ensure that only correctly folded proteins are released from the ER and that unfolded and/or misfolded proteins are retained and degraded. A number of...
متن کاملEndoplasmic Reticulum Stress, Genome Damage, and Cancer
Endoplasmic reticulum (ER) stress has been linked to many diseases, including cancer. A large body of work has focused on the activation of the ER stress response in cancer cells to facilitate their survival and tumor growth; however, there are some studies suggesting that the ER stress response can also mitigate cancer progression. Despite these contradictions, it is clear that the ER stress r...
