| 1 | 9535786 | Decreased BRCA1 expression levels may arrest the cell cycle through activation of p53 checkpoint in human sporadic breast tumors. |
| 2 | 9535786 | We also investigated possible relationships between BRCA1, p53, mdm-2 and p21(WAF1/CIP1) at the expression level. p53 expression was unaffected in almost all the specimens, mdm-2 was overexpressed in 18/35 specimens while 21/35 overexpressed p21. |
| 3 | 9535786 | Samples exhibiting reduced BRCA1 levels simultaneously overexpressed both p21 and mdm-2, showing that BRCA1, at certain levels, even reduced up to 2.7-fold, is functional and sufficient to upregulate p21, when p53 activity is inhibited by its negative regulator, the mdm-2. |
| 4 | 9535786 | On the contrary, specimens exhibiting more than 2.7-fold reduced BRCA1 levels, overexpressed p21 while mdm-2 expression was normal, allowing us to speculate that p21 transcriptional activation is due to p53 activity, in cases with dramatically decreased BRCA1 expression. |
| 5 | 9535786 | Our findings provide evidence, indicating that BRCA1 might affect cell cycle regulation and loss of BRCA1 function due to decreased expression leads to cell cycle arrest, through p53 and p21 genes. |
| 6 | 9662340 | As compared with parental cells and vector transfected clones, wtBRCA1 clones exhibited: (1) a slightly decreased proliferation rate (doubling time = 25 h as compared with 22 h for control cells); (2) a (3-6)-fold increase in sensitivity to chemotherapy drugs (adriamycin, camptothecin, and taxol); (3) increased susceptibility to drug-induced apoptosis; (4) reduced repair of single-strand DNA strand breaks; and (5) alterations in expression of key cellular regulatory proteins (including BRCA2, p300, Mdm-2, p21(WAF1/CIP1), Bcl-2 and Bax). |
