Proapoptotic gene pathway

Proapoptotic gene pathways" is not a single molecule or receptor but rather refers to a collection of genes and molecular mechanisms that promote apoptosis (programmed cell death). These pathways include both the intrinsic (mitochondrial) and extrinsic (death receptor-mediated) routes. Key proapoptotic genes encode proteins such as BAX, BAK, BID, BIM, PUMA, NOXA (members of the Bcl-2 family), as well as caspases like caspase 3, 8, and 9[1][2][3][4][5]. These proteins function in concert to regulate mitochondrial membrane permeability or transmit death signals from cell surface receptors. The balance between proapoptotic and anti-apoptotic factors determines whether a cell undergoes apoptosis in response to stress or damage[1][2][3]. Dysregulation of these pathways is implicated in diseases such as cancer (where apoptosis is suppressed), autoimmune disorders (where inappropriate apoptosis may occur), and neurodegenerative diseases[2][3]. Because "proapoptotic gene pathway" describes a functional network rather than an individual druggable target or protein entity, it should not be considered a canonical therapeutic target itself. **Note:** This entry is marked **is_incorrect = true** because "Proapoptotic gene pathway" does not refer to a specific molecule/receptor but rather an entire class of biological processes involving multiple genes and proteins. For structured data purposes—such as drug targeting—individual components like "BAX," "BAK," or "Caspase 3" should be used instead[1][2][4].
