Review demonstrates conflicting effects of Bcl-2 on radiation resistance in human cells, indicating its unsuitability as a routine prognostic marker.

Key Points

To review the structure and function of anti-apoptotic Bcl-2 family proteins and assess their relevance to radiation sensitivity and prognostic value in oncology.
Literature review of current data regarding Bcl-2 function as an anti-apoptotic protein.
Evaluation of in vitro studies examining Bcl-2 modulation of radiation sensitivity.
Assessment of in vivo clinical evidence evaluating Bcl-2 as a prognostic tumor marker.
Bcl-2 family proteins act as critical anti-apoptotic regulators primarily by inhibiting mitochondrial cell-death pathways.
Overexpression of Bcl-2 yields contradictory effects on in vitro cellular radiation sensitivity and in vivo tumor response, failing to consistently confer radioresistance.
Evidence does not support the routine clinical quantification of Bcl-2 as a reliable prognostic marker for radiation therapy outcomes.
