Role of intrinsic apoptosis in environmental exposure health outcomes

Trends Mol Med. 2023 Dec 5:S1471-4914(23)00264-2. doi: 10.1016/j.molmed.2023.11.003. Online ahead of print.ABSTRACTEnvironmental exposures are linked to diseases of high public health concern, including cancer, neurodegenerative disorders, and autoimmunity. These diseases are caused by excessive or insufficient cell death, prompting investigation of mechanistic links between environmental toxicants and dysregulation of cell death pathways, including apoptosis. This review describes how legacy and emerging environmental exposures target the intrinsic apoptosis pathway to potentially drive pathogenesis. Recent discoveries reveal that dynamic regulation of apoptosis may heighten the vulnerability of healthy tissues to exposures in children, and that apoptotic signaling can guide immune responses, tissue repair, and tumorigenesis. Understanding how environmental toxicants dysregulate apoptosis will uncover opportunities to deploy apoptosis-modulating agents for the treatment or prevention of exposure-linked diseases.PMID:38057226 | DOI:10.1016/j.molmed.2023.11.003
