BH3 domain mutation of proapoptotic genes Bad, Bmf and Bcl-G is rare in transitional cell carcinomas of the urinary bladder.
OBJECTIVE
Mounting evidence indicates that deregulation of apoptosis contributes to the development of human cancers. Bcl-2 family proteins regulate the intrinsic apoptosis pathway. The aim of this study was to explore the possibility that mutation of BH3 domain of proapoptotic Bcl-2 genes Bad, Bmf and Bcl-G might be involved in the development of urinary bladder cancer.


METHODS
We analysed the BH3 domains of Bad, Bmf and Bcl-G genes for the detection of somatic mutations in 43 transitional cell carcinomas (TCCs) of the urinary bladder by a single strand conformation polymorphism assay in this study.


RESULTS
There was no somatic mutation of BH3 domains of Bad, Bmf and Bcl-G genes in the TCC samples.


CONCLUSIONS
The data presented here indicate that BH3 domain mutation of these genes is rare in TCCs and may not contribute to the pathogenesis of TCCs.
