GSE134986: OMA1, DELE1 and HRI relay mitochondrial stress to the mammalian integrated stress response

• Organsim human
• Type RNASEQ
• Target gene
• Project ARCHS4

The goal of this study is to understand how mamalian cells respond to the mitochondial stress. Using Quant-seq, we identifed an integrated stress response signature in the cells with compromized mitochondria. Furthermore, using an unbiased CRISPRi genetic screen, we uncovered a novel signaling pathway, in which OMA1, DELE1 and HRI are three major players that relay the mitochondrial stress to the integated stress response. To further study the cellular response in the absence of this pathway, we again used Quant-seq to uncover alternative pathways that might play a role during the mitochondrial stress response.
