Snail and Twist expression in HMLE and MCF10A cells

Project description:Snail and Twist are two EMT inducer, expression of Snail or Twist will induce EMT in HMLE and MCF10A cells. By introducing Snail or Twist in HMLE and MCF10A cells, which lack the expression of these two proteins, will identify the genes are induced during EMT. We used microarray analysis to compare the gene expression profiles between the mammamry epithleial cells and the cells undergone EMT.

Effect of GRHL2 in HMLE+Twist-ER+4-OHT cells

Project description:Grainyhead genes are involved in wound healing and developmental neural tube closure. In light of the high degree of similarity between the epithelial-mesenchymal transitions (EMTs) occurring in wound healing processes and the cancer stem cell-like compartment of tumors, including TGF-β-dependence, we investigated the role of a Grainyhead gene (GRHL2) in oncogenic EMT. Grainyhead was specifically down-regulated in the claudin-low subclass of mammary tumors and in the basal-B subclass of breast cancer cell lines. Functionally, GRHL2 suppressed TGF-β-induced, Twist-induced or spontaneous EMT, enhanced anoikis-sensitivity, and suppressed mammosphere generation in mammary epithelial cells. These effects were mediated, in part, by its suppression of ZEB1 expression, through direct repression of the ZEB1 promoter. GRHL2 also inhibited Smad-mediated transcription, and up-regulated mir200b/c as well as the TGF-β receptor antagonist, BMP2. The expression of GRHL2 in the breast cancer cell line MDA-MB-231 triggered a mesenchymal-to-epithelial transition and sensitized the cells to anoikis. These results indicate that GRHL2 is a suppressor of the oncogenic EMT. 3 biologic replicates for each cell line. Comparison of HMLE+Twist-ER cells expressing GRHL2/pMIG vs. HMLE+Twist-ER cells expressing empty pMIG.

ChIP-seq for SMARCE1 and SMARCC1 in non-invasive and invasive HMLE-Twist-ER cells

Project description:We find that in invasive HMLE-Twist-ER cells, SMARCE1 binds to ILF3 and is localized to ILF motifs. In contrast, ILF motifs were not enriched at SMARCE1-bound sites in noninvasive HMLE-Twist-ER cells or at SMARCC1-bound sites.

RNA-seq of two human mammary epithelial cell lines (HMLE and HMLE-Twist-ER) treated with 4-hydroxytamoxifen vs control

Project description:Immortalized non-cancerous human mammary epithelial cells (HMLE) were transfected to express the murine fusion protein Twist1-estrogen receptor(point mutation G525R) (HTER). Twist1-mediated gene expression is activated by stimulation with 4-hydroxytamoxifen for several days and induces an epithelial-mesenchymal transition (EMT) in HTER cells. In breast cancer, EMT equips cancer cells for metastasis and therapy resistance. As control, HTER cells were treated with vehicle (methanol). As additional controls, HMLE cells were stimulated with 4-hydroxytamoxifen or methanol, respectively. Prior to RNA sequencing, EMT-undergoing HTER cells were sorted by fluorescence-activated cell sorting (FACS) based on E-Cadherin and CD44 surface protein levels into three populations, epithelial (E), hybrid epithelial-mesenchymal (EM), and mesenchymal (M): E-Cadherin_high_CD44_low (E), E-Cadherin_medium_CD44_medium (EM), and E-Cadherin_low_CD44_high (M).

Expression data for HMLE-based EMT models

Project description:EMT was induced using stable overexpression of 1 of 4 EMT transcription factors (FOXQ1, TWIST1, ZEB2, and SNAI1) in the HMLE cell line. HMLE cells with ectopic LACZ expression were used as control cells.
