Bax mutations in cell lines derived from hematological malignancies

Leukemia. 1995 Nov;9(11):1828-32.


Many genes are involved in cell cycle control, DNA repair and induction of cell death. Alterations in these genes have been responsible for the development of cancer as well as for resistance to cancer therapy. Recently, an emerging family of bcl2-like genes has been identified that plays a role in the regulation of cell death. Its members are highly conserved in several domains which have been shown to be important for homodimerization or heterodimerization. The ratio between BAX/BCL2 heterodimers and BAX/BAX homodimers appears to be pivotal in deciding the life of death of a cell. We recently detected mutations in evolutionary highly conserved domains of the bax gene in cell lines derived from hematologic malignancies. Similar artificially generated mutations in other bcl2-like family members bcl2, bclxl, or ced9 have been shown to alter their function. This suggests a role for bax mutations in the multi-step pathogenesis of hematological malignancies.
