Project description:The winged helix transcription factor Foxl1 is a marker for progenitor cells and their descendants in the mouse liver in vivo. Here, we purify progenitor cells from Foxl1-Cre; RosaYFP mice and evaluate their proliferative and differentiation potential in vitro. Treatment of Foxl1-Cre; RosaYFP mice with 3,5-diethoxycarbonyl-1,4-dihydrocollidine diet led to an increase of the percentage of YFP-labeled Foxl1+ cells. Clonogenic assays demonstrated that up to 3.6% of Foxl1+ cells had proliferative potential. Foxl1+ cells differentiated into cholangiocytes and into hepatocytes in vitro, depending on the culture condition employed. Microarray analyses indicated that Foxl1+ cells express stem cell markers such as Prom1 as well as differentiation markers such as Ck19 and Hnf4a. Thus, the Foxl1-Cre; RosaYFP model allows for easy isolation of adult hepatic progenitor cells that can be expanded and differentiated in culture. Refer to individual Series. This SuperSeries is composed of the following subset Series: GSE28890: Foxl1-Cre-marked Adult Hepatic Progenitors Have Clonogenic and Bi-Lineage Differentiation Potential - Time Course GSE28891: Foxl1-Cre-marked Adult Hepatic Progenitors Have Clonogenic and Bi-Lineage Differentiation Potential - Differentiated vs Primary

Thus, the Foxl1-Cre; RosaYFP model allows for easy isolation of adult hepatic progenitor cells that can be expanded and differentiated in culture. There were 26 samples used in the analysis. Typically 4 replicates for each of 7 conditions, except for two condtions which had only 3 replicates. Day 0 samples are non-parenchymal cells without DDC treatment. YFP_pos samples are YFP-expressing non-parenchymal cells induced by Foxl1-CRE after 3, 7 or 14 days of DDC treatment. YFP_neg samples are analogous but do not expressed YFP.

Project description:We found that hepatic injury induced by PTEN loss establishes a selection pressure for tumorinitiating cells (TICs) to proliferate and form mixed lineage tumors. The Pten null mice demonstrate escalating levels of hepatic injury prior to proliferation of hepatic progenitors. Attenuation of hepatic injury by deleting Akt2 reduces progenitor cell proliferation and delays tumor development. Treatment of double mutant mice with 3,5-dietoxycarbonyl-1,4 dihydrocollidine (DDC) shows that the primary effect of AKT2 loss is attenuation of hepatic injury and not inhibition of progenitor cell proliferation in response to injury. Pten/Akt2 double mutant (PtenloxP/loxP; Akt2-/-; Alb-Cre+) (Dm) were generated by crossing the PtenloxP/loxP; Alb-Cre+ (Pm) with the Akt2-/- mice [19]. Control animals are PtenloxP/loxP; Albumin (Alb)-Cre-.

Project description:The mechanisms regulating breast cancer differentiation state are poorly understood. Of particular interest are molecular regulators controlling the highly aggressive and poorly differentiated traits of basal-like breast carcinomas. Here we show that the Polycomb factor EZH2 maintains the differentiation state of basal-like breast cancer cells, and promotes the expression of progenitor-associated and basal-lineage genes. Specifically, EZH2 regulates the composition of basal-like breast cancer cell populations by promoting a M-bM-^@M-^\bi-lineageM-bM-^@M-^] differentiation state, in which cells co-express basal- and luminal-lineage markers. We show that human basal-like breast cancers contain a subpopulation of bi-lineage cells, and that EZH2-deficient cells give rise to tumors with a decreased proportion of such cells. Bi-lineage cells express genes that are active in normal luminal progenitors, and possess increased colony formation capacity, consistent with a primitive differentiation state. We found that GATA3, a driver of luminal differentiation, performs a function opposite to EZH2, acting to suppress bi-lineage identity and luminal progenitor gene expression. GATA3 levels increase upon EZH2 silencing, leading to the observed decrease in bi-lineage cell numbers. Our findings reveal a novel role for EZH2 in controlling basal-like breast cancer differentiation state and intra-tumoral cell composition. Total of four treatments (HCC70 cells stably expressing shEZH2, shEED, or EZH2 cDNA, and MDA-MB-468 cells stably expressing shEZH2) were done in duplicates, each with its own control.
