Project description:To uncover genes regulated by mTORC1 and estradiol in uterine Tsc2-null LAM like cells, we performed RNAseq on uteri from 12-week old wild-type (WT) and uterine-specific Tsc2-null (KO) mice that were either untreated (intact), oopherectomized (ovx) or oopherectomized + treated with 17β-estradiol pellets (E2) for 8 weeks. We identified genes that were both estradiol- and TSC2-mediated.
Project description:Three independent replicates of 4 groups of immature (19/20 days of age) Alpk:APfCD-1 mice were treated with arachis oil (AO) vehicle, 2.5ug/kg 17beta-estradiol (E2), 2ug/kg diethylstilbestrol (DES), or 50mg/kg genistein (GEN), via 3 daily subcutaneous injection, and sacrificed 72hr after initial dose.

Project description:We are using ACI and BN rats, which differ markedly in their susceptibility to 17beta-Estradiol (E2)-induced mammary cancer, to identify genetic variants and environmental factors that determine mammary cancer susceptibility. The objective of this study was to characterize the cellular and molecular responses to E2 in the mammary glands of ACI and BN rats to identify qualitative and quantitative phenotypes that associate with and/or may confer differences in susceptibility to mammary cancer. Female ACI and BN rats were treated with E2 for 1, 3 or 12 weeks and cell proliferation, apoptosis, differentiation and gene expression were evaluated. The luminal epithelium of ACI rats exhibited a rapid and sustained proliferative response to E2. By contrast, the proliferative response exhibited by the mammary epithelium of BN rats was restrained and transitory. Moreover, the epithelium of BN rats appeared to undergo differentiation in response to E2, as evidenced by production of milk proteins as well as luminal ectasia and associated changes in the extracellular matrix (ECM). Marked differences in expression of genes that encode proteins with well-defined roles in mammary gland development (Pgr, Wnt4, Tnfsf11, Prlr, Stat5a, Areg, Gata3), differentiation and milk production (Lcn2, Spp1), regulation of extracellular environment (Mmp7, Mmp9), and cell-cell or cell-ECM interactions (Cd44, Cd24, Cd52) were observed. We propose that these cellular and molecular phenotypes are heritable and may underlie, at least in part, the differences in mammary cancer susceptibility exhibited by ACI and BN rats. Two groups of 17beta-estradiol treated female rats were compared. Five ACI and five BN rats were treated with 17beta-estradiol for 12 weeks. Total RNA was isolated from the mammary glands of these animals, labeled, and hybridized to Affymetrix Rat Genome 230 2.0 Arrays (Affymetrix Inc.). Significantly differentially expressed genes were found between these groups.
