WebFeb 3, 2024 · PERK activates apoptotic cascades in multiple ways. Apoptosis is ultimately induced by sustained PERK activation after E 2 therapy in endocrine-resistant breast cancer cells. The classical way that PERK induces apoptosis is by activating ATF4 and the downstream pro-apoptotic protein CHOP. WebMar 26, 2024 · The unfolded protein response consists of 3 branches controlled by ER stress sensor proteins, which include PERK (protein kinase RNA-like ER kinase). Activated PERK phosphorylates eIF2α (eukaryotic initiation factor 2 alpha), resulting in inhibition of global protein synthesis. matt gaetz indictment news

"WebIn the present study, we examined whether proteasome inhibition alters the protein kinase receptor-like endoplasmic reticulum kinase (PERK). Our studies demonstrate that proteasome inhibitors induce the transient activation of PERK in both primary rat neurons as well as the N2a neural cell line. " - Perk activation
