Chemical compounds that suppress hypoxia-induced stress granule formation enhance cancer drug sensitivity of human cervical cancer HeLa cells

Abstract excerpt

In eukaryotic cells, when exposed to certain types of stress including hypoxia, eIF2α is phosphorylated by several kinases including protein kinase R (PKR) and PKR-like endoplasmic reticulum kinase (PERK). Subsequently, protein translation is stopped and stress granules (SGs) are formed. Cancer cells form SGs under hypoxia. SGs accumulate apoptosis-related molecules and play anti-apoptotic roles. Thus,...
