Expression of BRCA-1 and ERα are reduced in DMBA-induced mammary adjacent tissues and tumors. a Bands are representative immunocomplexes for BRCA-1 and ERα in control mammary gland, and mammary adjacent tissue and tumors obtained from four (1 through 4) DMBA-treated rats; b Bars represent means ± SEM of quantitation (fold change of control) of BRCA-1 and ERα protein corrected for GAPDH protein as internal standard in mammary adjacent tissues and tumors from 8 animals/group (n = 8). Different letters represent statistical differences (P < 0.05)
