CONCLUSION : This result suggests that MMP12 A1082G polymorphism may be related to prognosis in breast cancer patients.
The importance of a genetic polymorphism (A/B allele) of poly (ADP-ribose) polymerase (PARP) pseudogene on chromosome 13q34-qter , and PARP enzyme activities in the development of human breast cancer were evaluated in a cancer case-control study.
The activity of poly (ADP-ribose) polymerase (PARP) is activated upon recognition of DNA strand breaks by its DNA-binding domain and the stimulation of this nuclear enzyme seems to be an early response of cells exposed to a variety of different DNA-damaging agents.
The balanced DNA excision-repair process is accompanied by a proportional consumption of NAD for poly (ADP-ribose) synthesis.
