The C-terminal region of Xpc is dispensable for the transcriptional activity of Oct3/4 in mouse embryonic stem cells

ABSTRACT: The transcription factor Oct3/4 is essential to maintain pluripotency in mouse embryonic stem (ES) cells. It was reported that the Xpc DNA repair complex is involved in this process. Here we examined the role of Xpc on the transcriptional activation of the target genes by Oct3/4 using the inducible knockout strategy. We found that the removal of the C-terminal region of Xpc, including the interaction sites with Rad23 and Cetn2, showed faint impact on the gene expression profile of ES cells and the functional Xpc-ΔC ES cell lines retained proper gene expression profile as well as pluripotency to contribute chimeric embryos. These data indicated that the C-terminal region of Xpc is dispensable for the transcriptional activity of Oct3/4 in mouse ES cells. An inducible knockout ES cell line of Xpc with the Cre-loxP system was generated and gene expression was measured without Xpc deletion, after 4 days of Xpc deletion or constitutive knocked out cells. Each sample was prepared in triplicate.

Zscan10 is dispensable for maintenance of pluripotency in mouse embryonic stem cells

Project description:Zinc finger and SCAN domain-containing 10 (Zscan10, also known as Zfp206) encodes a transcription factor that has been reported to be involved in the maintenance of pluripotency in mouse embryonic stem (ES) cells. Here we generated inducible knockout ES cells for Zscan10 using the Cre-loxP system and analyzed its function. We succeeded in establishing Zscan10-null ES cells and confirmed their pluripotency by the generation of chimeric embryos. Our results clearly indicate that Zscan10 is dispensable for the ability of self-renewal and differentiation in ES cells. An inducible knockout ES cell line of Zscan10 with the Cre-loxP system was generated and gene expression was measured without Zscan10 deletion or constitutive knocked out cells. Each sample was prepared in triplicate.

Induction of trophoblast stem cells from embryonic stem cells by forced repression of Oct3/4.

Project description:To characterize the transdifferentiation of embryonic stem (ES) cells into trophoblast stem (TS) cells triggered by forced repression of Oct3/4, we performed whole-genome expression analysis after tetracycline (Tet)-induced knockout of Oct3/4. A Tet-inducible Oct3/4 knockout ES cell line ZHBTc4 was treated with Tet for 4 days in the presence of FGF4 and mouse embryonic fibroblasts (MEFs). A total of 15 samples from Day 0 to Day 4 were analyzed in three biological replicates.

Dissecting Oct3/4-regulated gene networks in embryonic stem cells by expression

Project description:POU transcription factor Pou5f1 (Oct3/4) is required to maintain ES cells in an undifferentiated state. Here we show that global expression profiling of Oct3/4-manipulated ES cells delineates the downstream target genes of Oct3/4. Combined with data from genome-wide chromatin-immunoprecipitation assays, this analysis identifies not only primary downstream targets of Oct3/4, but also secondary or tertiary targets. Furthermore, the analysis also reveals that downstream target genes are regulated either positively or negatively by Oct3/4. Identification of a group of genes that show both activation and repression depending on Oct3/4 expression levels provides a possible mechanism for the requirement of appropriate Oct3/4 expression to maintain undifferentiated ES cells. As a proof-of-principle study, one of the downstream genes, Tcl1, has been analyzed in detail. We show that Oct3/4 binds to the promoter region of Tcl1 and activates its transcription. We also show that Tcl1 is involved in the regulation of proliferation, but not differentiation, in ES cells. These findings suggest that the global expression profiling of gene-manipulated ES cells can help to delineate the structure and dynamics of gene regulatory networks. Keywords: development or differentiation design,time series design

Gene expression profile after Dax1 deletion in ES cells

Project description:To investigate the function of Dax1 in mouse ES cells, whole genome microarray expression profiling was employed to identify genes that are potentially affected by the deletion of Dax1. An inducible knockout ES cell line of Dax1 with the Cre-loxP system was generated and gene expression was measured (i) without Dax1 deletion, (ii) after 4 days of Dax1 deletion, or (iii) after several passags of Dax1 deletion. Each sample was prepared in triplicate.

Targeting OCT3 attenuates doxorubicin-induced cardiac injury

Project description:Doxorubicin is a commonly used anticancer agent that can cause debilitating and irreversible cardiac injury. The initiating mechanisms contributing to this side effect remain unknown, and current preventative strategies only offer modest protection. Using stem cell-derived cardiomyocytes from patients receiving doxorubicin, we probed the transcriptomic landscape of solute carriers and identified OCT3 (SLC22A3) as a critical transporter regulating the cardiac accumulation of doxorubicin. Functional validation studies in mice revealed that targeting OCT3 can attenuate cardiac dysfunction without compromising the anticancer properties of doxorubicin. These findings provide a rationale for the development of targeted approaches to mitigate this debilitating toxicity
