We used the proliferation test (E-screen assay) in MCF-7 breast cancer cells and reverse transcription quantitative polymerase chain reaction (RT-qPCR) analysis of TFF1 gene expression to analyze estrogenicity of the studied compounds. RT-qPCR has proven to be a fast and valuable molecular technique in gene expression quantification. HBCD but not TBBPA increased cell proliferation in MCF-7 cells and up-regulates TFF1 gene expression in a concentration-dependent manner. Anti-estrogen ICI 182,780 inhibits up-regulation of TFF1 by HBCD. We showed that HBCD displays estrogen-like effects on MCF-7 cells. TBBPA, on the other hand, has not shown any estrogenic effect mediated by the estrogen receptor alpha.
