摘要: Identifying the conditions and kinetics of induction BRCA2 gene expression may implicate roles for function tumor suppressor gene. In this study, mRNA is shown to be regulated by cell cycle associated with proliferation in normal tumor-derived breast epithelial cells. Cells arrested G(0) or early G1 contained low levels mRNA. After release into a proliferating state, cells produced maximum late S-phase. Similar control was observed fractions exponentially growing isolated centrifugal elutriation. Expression independent bulk DNA synthesis. addition, up-regulation appeared similar those BRCA1, suggesting that two genes could commonly controlled. These results imply these are utilized during growth have protective role cellular proliferation.
