Project description:Transcriptional profiling of different mouse mammary cellular compartments (basal, luminal and stromal) under define hormone treatments: estrogen, progesterone, estrogen plus progesterone and the vehicle control. Goal was to determine the effect of ovarian hormones on mammary cellular compartment gene expression. Four-condition experiment within each cellular compartment. vehicle vs. estrogen, progesterone and estrogen plus progesterone. Biological replicates: 3 vehicle control, 4 estrogen treatment, 3 progesterone treatment, 4 estrogen plus progesterone treatment in each epithelial compartment (luminal, basal). 3 vehicle control, 3 estrogen, 3 progesterone, 3 estrogen plus progesterone in the stromal compartment.

Project description:In the present study, to identify potential paracrine factor for the stromal regulation of E2-induced epithelial cell proliferation, we treated epithelial and stromal cell populations of mouse uterine primary co-culture with either oil or E2. Three independent RNA pools prepared for each population were then subjected to the Affymetrix gene chip analysis for the whole mouse genome transcripts. Our data revealed up-regulation of 119 genes and down-regulation of 28 genes in epithelial cell populations and up-regulation of 144 genes and down-regulation of 192 genes in stromal cell population. We analyzed whole gnenome transcription from epithelial and stromal cell populations of mouse uterine primary co-culture using the Affymetrix GeneChip® Mouse Gene 1.0 ST Array (vehicle vs. E2). 3 replicates were performed.
Project description:Therapeutic targeting MTDH-SND1 interaction Suppresses Breast Cancer Progression and Metastasis (GSE159764). To further elucidate the tumor intrinsic effects of the targeting and the adverse effects on normal mammary epithelial cells Mouse mammary tumor cells and normal mammary epithelial cells were isolated from transgenic mouse models and cultured in vitro 3D spheroids system. MMTV-PyMT tumor cells from cKO mouse in tumorsphere culture were treaed with tamoxifen to induce Mtdh KO, and compared to the mock treatment which maintain wild type Mtdh. Thus the tumor intrinsic effects can be determined Normal mammary epithelial cells were isolated from mouse mammary gland and cultured in vitro in mammosphere. The cells were treated with inhibitor C26A6 vs control and thus the adverse effects on normal MECs can be determined.
