<h4>Unlabelled</h4>The Yes-associated protein (YAP)/Hippo pathway has been implicated in tissue development, regeneration, and tumorigenesis. However, its role in cholangiocarcinoma (CC) is not established. We show that YAP activation is a common feature in CC patient biopsies and human CC cell lines. Using microarray expression profiling of CC cells with overexpressed or down-regulated YAP, we show that YAP regulates genes involved in proliferation, apoptosis, and angiogenesis. YAP activity pro ...[more]

RISC-mediated control of selected chromatin regulators stabilizes ground state pluripotency of mouse embryonic stem cells (miRNA-Seq)

Project description:We performed an integrated analysis of RNA and proteins at the transition between naÃ¯ve ES cells and cells primed to differentiate. During this transition, mRNAs coding for chromatin regulators were specifically released from translational inhibition mediated by RNA-Induced Silencing Complex (RISC). This suggests that, prior to differentiation, the propensity of ES cells to change their epigenetic status is hampered by RNA interference. The expression of these chromatin regulators was reinstated following acute inactivation of RISC, and it correlated with loss of stemness markers and activation of early cell differentiation markers in treated ES cells. We evaluated global miRNA profiles of embryonic stem cells cultured in either 10%FCS+LIF or 2i+LIF and of Epiblast-Like Aggregates derived from ES cells in 10%FCS+LIF or 2iL+LIF.

Genome wide analysis of STAT3-mediated transcription and binding sites in mouse female germ stem cell (ChIP-seq)

Project description:Activation of JAK-STAT3 signaling by leukemia inhibitory factor (LIF) is required for maintaining self-renewal of mouse embryonic stem cells (mESCs). STAT3 perform cell type-specific roles in different cell type, here we revisit the role of STAT3 using mouse female germ stem cell (mFGSCs). We applied CRISPR/Cas9 system to generate Stat3 knockout FGSCs and then observed cell growth inhibition and cell cycle arrest in KO cell line. By combining genome wide ChIP-Seq and RNA-Seq, we identified 5990 STAT3 binding sites and discovered serval genes specific regulated by STAT3 that were involved in stem cell proliferation and female gonad development in FGSCs. In general, we identify key roles of STAT3 for sustains self-renewal and proliferation for FGSCs in this study.

Genome-wide analysis revealed a crosstalk between p53 and the pluripotent gene networks in mouse embryonic stem cells (expression)

Project description:The tumor suppressor p53 regulates the differentiation of embryonic stem (ES) cells upon DNA damage. However, our understanding of this critical tumor suppressive role of p53 in ES cells is limited, mainly because of the lack of molecular mechanism. Here, we report a widespread cross-regulation of p53-mediated DNA damage signaling and the pluripotent gene network in ES cells using chromatin-immunoprecipitation assay-based sequencing (ChIP-seq) and gene expression microarray. Upon DNA damage, p53 directly regulates the transcription of 3644 genes (p<0.005) in mouse ES cells. Genome-wide analysis revealed a dramatic difference between the regulation of p53-activated and -repressed genes. p53 mainly regulates the promoter regions of activated genes, whereas the main regulatory regions for repressed genes reside in distal regions. Among p53-repressed genes, many are pluripotent transcription factors of ES cells, such as Oct4, Nanog, Sox2, Esrrb, c-Myc, n-Myc and Sall4. Strikingly, these transcriptional factors also directly regulate the transcription of the Trp53 gene, highlighting a previously under-estimated transcriptional regulation of p53 in ES cells. Therefore, p53 signaling and ES pluripotent transcriptional networks form an intertwined circuitry. Together, our results provide mechanistic insights into the crosstalk of p53-mediated DNA damage and ES cell "stemness" transcriptional gene networks and shed light on the tumor suppressive function of p53 in ES cells. The goal of this experiment is to identify the gene expression changes after adriamycin treatment in a p53-dependent manner. Total six samples: triplicates for untreated mES cells and triplicates for mES cells treated with adriamycin.

Expression data of embryonic stem (ES) cells from both control and Prmt6 overexpressed population

Project description:ES cells are able to self-renew and remain pluripotent. These characteristics are maintained by both genetic and epigenetic regulators. Protein arginine methyltransferase (PRMT) 4 and 5 are shown to be important in early embryonic development and in ES cells. PRMT6-mediated di-methylation of histone H3 at arginine 2 (H3R2me2) can antagonize the tri-methylation of histone H3 at lysine 4, which marks active genes. However, it is unclear whether PRMT6 and PRMT6-mediated H3R2me2 play crucial roles in early embryonic development and ES cell identity. In this study, we investigate their functions using mouse ES cells as the model. We used microarray (Affymetrix GeneChip Mouse Gene 1.0ST) to examine the global change of gene expression in mouse ES cells when Prmt6 was overexpressed and identified distinct classes of genes that are up-regulated and down-regulated during this process. Mouse ES cells were transfected with either pCAGIP.puro empty vector (control) or Prmt6 overexpressing plasmid (P+6 OE). After 3 days of selection by puromycin, cells from both populations were subjected to RNA extraction and hybridization on Affymetrix microarrays.
