Anti-Apoptotic Pathways

Meaning

Anti-apoptotic pathways represent the intricate cellular mechanisms that actively inhibit apoptosis, which is the programmed cell death process. These protective pathways are essential for maintaining tissue homeostasis, cellular longevity, and preventing premature cell loss, especially in hormonally sensitive tissues. Key components often involve the BCL-2 family of proteins, which act to stabilize mitochondrial membranes and block the execution phase of cell death. Clinical relevance is high, as the dysregulation of these pathways is implicated in conditions ranging from cancer progression to neurodegenerative disorders.
