BRCA1 and breast carcinoma: Consistent with our array studies we note that there was a highly significant induction of CCNG2, Cited2 and BRCA1 with the most potent induction being observed for CCNG2. This response was conserved between the MCF-7 breast cancer cell line (as we would predict based on our array studies) as well as the U2OS osteosarcoma cell line (data not shown).
