Heat Shock Factor 1 (HSF1) acquires transcriptional competence under 17b-estradiol in ERa-positive breast cancer cells [RNA-seq]

Project description:Heat Shock Transcription Factor 1 (HSF1) is a well-known regulator of gene expression during acute environmental stress that enables the cells to survive. Its high level in estrogen receptor-positive breast cancer patients correlated with a worse prognosis. Here, we demonstrated that 17β-estradiol (E2) as well as bisphenol A (BPA) and propyl pyrazole triol (PPT, ERα agonist) led to HSF1 phosphorylation on S326 in ERα positive mammary breast cancer cells, but not in ERα-negative ones. We showed that ERK1/2 signaling was involved in this process and down-regulation of ERα expression abrogated it. E2activated HSF1 was transcriptionally potent. Chip-Seq and RNA-Seq analyses revealed that it could modulate the expression of several genes known to be essential for breast cancer cells growth and/or ERα action, i.e. HSPB8, LHX4, PRKCE, WWC1, and GREB1. Our findings indicate that a positive feedback loop between ERα and HSF1 signaling may exist which support the growth of estrogen-dependent tumors.

Gene expression signatures in uteri from nuclear and membrane effects of Estradiol on Estrogen receptor ERÎ±

Project description:To further study gene expression regulated by 17b-estradiol in uteri, we have employed whole gene microarray profiling to identify genes specifically regulated by the Estrogen receptor ERÎ± localized either at the plasma membrane or in the nucleus. Two mice models have been used, the mice named ERa-AF2Â° (named AF2_KO and on C57BL6/J background) in which 7 aminoacids have been deleted in the AF2 domain and the mice C451A-ERa (named MISS_KO and on C57BL6/N background) mutated for the C451 into Ala on ERa. Control littermates were used for each mutant mice respectively name AF2_WT or MISS_WT. 17b-estradiol induced gene expression in uteri from ovariectomized mice was measured after 6 hours exposure to 0 (PLB) and 8Âµg/kg of 17b-estradiol (E2) injected subcutaneously in castor oil.
