Comparison of Ets2-null and control ES cell derived lineages

ABSTRACT: Ets2-null ES cells are defective in differentiating into cardiac myocytes, evidenced by the lack of spontaneous beating, cardiac transcription factors and structural proteins. With the Phalanx mouse Onearray v2, we compared the gene expression profiles of cells derived from Ets2-null and wildtype ES cells.

Comparison of Ets2-null and control ES cell derived lineages

Project description:Ets2-null ES cells are defective in differentiating into cardiac myocytes, evidenced by the lack of spontaneous beating, cardiac transcription factors and structural proteins. With the Phalanx mouse Onearray v2, we compared the gene expression profiles of cells derived from Ets2-null and wildtype ES cells. Standard embryoid body culture protocol was used to induce differentiation of murine ES cells. On the 10th day, replicates of either Ets2-null or control wildtype EB culture were collected in Trizol for total RNA extraction. Microarray was preformed by Phalanx.

ETS2 and Mesp1 trans-differentiate human dermal fibroblasts into cardiac progenitors

Project description:We explored the role of mammalian ETS1/2 and Mesp homologues of cardiogenic transcription factors of Ciona intestinalis, to convert primary human dermal fibroblasts into cardiac progenitors. ETS1/2 and Mesp homologues of cardiogenic transcription factors of Ciona intestinalis, to convert primary human dermal fibroblasts into cardiac progenitors. Here we show murine Ets2 has an obligatory role for directing cardiac progenitors during cardiopoesis in embryonic stem cells. ETS2 converted fibroblasts into KDR/Flk1+ replicative cells but, like the purported cardiac master regulatory gene Mesp1, could not by itself generate cardiac progenitors de novo from fibroblasts. Co-expression of both Ets2 and Mesp1, however, successfully reprogrammed differentiated fibroblasts into cardiac progenitors, as shown by the de novo appearance of core cardiac transcription factors, gap junction proteins, sarcomeric proteins, electrical activity and contractility. ETS2 and Mesp1 sit at the pinnacle of the cardiopoesis regulatory hierarchy and are well suited for treating human heart disease. Co-expression of both Ets2 and Mesp1, reprogrammed differentiated fibroblasts into cardiac progenitors

Dynamic BAF chromatin remodeling complex subunit inclusion promotes temporally distinct gene expression programs in cardiogenesis [RNA-Seq II]

Project description:We performed differential mRNA analysis in WT and BRG1 KO cells during cardiac precursor and cardiomyocytes stages of directed differention of mouse ES cells to cardiac myocytes. We show that BRG1 activity is higher in cardiac precursor cells and severely reduced in cardiac myocytes

Ets2 is required for trophoblast stem cell self renewal

Project description:The Ets2 transcription factor is essential for the development of the mouse placenta and for generating signals for embryonic mesoderm and axis formation. Using a conditional targeted Ets2 allele, we show that Ets2 is essential for trophoblast stem (TS) cells self renewal. Inactivation of Ets2 results in slower growth, increased expression of a subset of differentiation associated genes and decreased expression of several genes implicated in TS self renewal. Among the direct TS targets of Ets2 is Cdx2, a key master regulator of TS cell state. In addition other Ets2 responsive genes include Pace4, Errb, Socs2 and Bmp4. Thus Ets2 contributes to the regulation of multiple genes important for maintaining the undifferentiated state of TS cells and as candidate signals for embryonic development.

Expression Data from Normal or Tumor Fibroblasts With or Without Ets2

Project description:The mechanisms involved in epithelium-stroma interactions remain poorly understood, despite the importance of the microenvironment during tumorigenesis. Here, we studied the role of the Ets2 transcription factor in tumor-associated fibroblasts in the MMTV-PyMT mammary tumor model. Inactivation of Ets2 specifically in fibroblasts using Fsp-cre significantly reduced tumor growth, in contrast to Ets2 inactivation in epithelium, in which no differences in tumor growth were observed. Microarray analysis on isolated fibroblasts demonstrated the important role of Ets2 in remodeling of the extracellular matrix and angiogenesis in these cells. At the molecular level, Ets2 regulated Mmp9 expression through direct binding to the promoter region. Tumors lacking Ets2 in fibroblasts had diminished blood vessels. We also found a significant correlation between phosphorylation of ETS2 and MMP9 levels in stroma of human breast cancer samples. Collectively, our results suggest Ets2 uniquely contributes to angiogenesis from fibroblasts in the tumor microenvironment.

Gene expression profiles of tumor and paired normal lung tissues from primary non-small cell lung cancer (NSCLC) patients in Taiwan.

Project description:Genome-wide expression profiling of NSCLC patients were done using Phalanx Human OneArray chip. The surgically resected tumor tissue and corresponding normal tissue were collected from 21 patients diagnosed with primary NSCLC admitted to Taipei Veterans General Hospital, Taiwan.
