PRKAA1 and neoplasm: Consequently, BRCA1 deficiency impairs stress‐induced mitophagy through blocking ataxia‐telangiectasia mutated (ATM)‐AMP‐activated protein kinase (AMPK)‐Dynamin‐related protein 1 (DRP1)‐mediated mitochondrial fission and triggers NLRP3 inflammasome activation, which creates a tumor‐associated microenvironment, thereby facilitating tumor proliferation and metastasis.
