摘要: AbstractInterference with the expression and/or functions of multifunctional tumor suppressor BRCA1 leads to a high risk breast and ovarian cancers. is usually activated by estrogen (E2) liganded ERα receptor. Activated considered as potent transcription factor which activates various genes two pathways. A classical pathway, binds directly E2-responsive elements (EREs) in promoters responsive non-classical pathway where indirectly appropriate gene promoter. In our previous study, HTLV-1Tax was found strongly inhibit induced while stimulating ERE dependent genes. TPA strong PKC activator induce HTLV-1. Here we examined effect on controlled region MCF-7 cells Tax activity these Our results showed stimulatory both with...
