Genome-wide profiling of genes during differentiation of wild (WT) murine embryonic stem cells (ESCs), scrambled control (SCR) ESCs, and Strip2 silenced (KD) ESCs

Project description:The role of Striatin Interacting Protein 2 (Strip2) in differentiation of embryonic stem cells (ESCs) is still under debate. Strip2 silenced (KD) ESCs were differentiated for 4, 8, 12, and 16 days. We show that Strip2 is distributed in the perinucleus or nuclei of wild type (WT) undifferentiated ESCs, but is localized in high-density nuclear bodies in differentiated cells. CellNet analysis of microarray gene expression data for KD and scrambled control (SCR) embryoid bodies (EBs), as well as immunostainings of key pluripotent factors, demonstrated that KD ESCs remain undifferentiated. This occurs even in 16-day old EBs, which possessed a high tumorigenic potential. Correlated with very high expression levels of epigenetic regulator genes, Hat1 and Dnmt3, enzymatic activities of the histone acetyltransferase type B (HAT1) and DNA (cytosine-5)-methyltransferase 3 beta (DNMT3b) were higher in differentiated 16-day old KD EBs than in SCR or WT EBs. The expression levels of let-7, 290 and 302 microRNA families were opposed in KD ESCs, while KD EBs had levels comparable to WT and SCR ESCs during differentiation. This demonstrates that Strip2 is critical to the onset of differentiation, regulating expression of epigenetic regulators, HAT1 and DNMT3b, as well as microRNAs involved in pluripotency.

Genome-wide profiling of genes during differentiation of wild type (WT) murine embryonic stem cells (ESCs), scrambled control (SCR) ESCs and Mageb16-depleted (KD) ESCs

Project description:The Melanoma-associated Antigen gene family (MAGE) generally encodes for tumour antigens. We recently have identified one of the MAGE gene members, Mageb16 to be highly expressed in undifferentiated murine embryonic stem cells (mESCs). The role of Mageb16 for the differentiation of the pluripotent stem cells is completely unknown. Here we demonstrate that Mageb16 (41 kDa) is distributed in cytosol and/or in surface membrane in undifferentiated mESCs. A transcriptome study was performed with differentiated short hairpin RNA (shRNA)-mediated Mageb16 knockdown (KD ESCs) and scrambled control (SCR) ESCs until a period of 22 days. Mageb16 KD ESCs mainly differentiated towards mesodermal derivatives such as cardiovascular lineages. Mesoderm-oriented differentiation initiated biological processes such as adipogenesis, osteogenesis, limb morphogenesis and spermatogenesis were significantly enriched in the differentiated Mageb16 KD ESCs. Cardiomyogenesis in differentiated KD mESCs was stronger when compared to differentiated SCR and wild mESCs. The expression of non-coding RNA (ncRNA) Lin28a and other epigenetic regulatory genes, nucleocytoplasmic trafficking and genes participating in spermatogenesis have also declined faster in the differentiating Mageb16 KD ESCs. We conclude that Mageb16 plays a crucial role for differentiation of ESCs, specifically to the mesodermal lineages. Regulative epigenetic networks and nucleocytoplasmic modifications induced by Mageb16 may play a role for the critical role of Mageb16 for the ESCs differentiation.

Expression data from the control and Jmjd1c KD ESCs

Project description:The roles of histone demethylases (HDMs) for the establishment and maintenance of the pluripotent state are incompletely defined. Here, we show that JmjC domain-containing protein 1c (Jmjd1c), a putative histone H3 Lys 9 (H3K9) demethylase, is required for mouse embryonic stem cell (ESC) self-renewal. To understand how Jmjd1c knockdown (KD) and resultant changes in the H3K9 methylations would affect ESCs at a global gene expression level, we compared the whole genome transcriptomes between the control and Jmjd1c KD ESCs (6 samples, including 2 shNT control samples and 4 shJmjd1c samples, 2 from #3 and 2 from #4 shRNA, respectively) using affymetrix microarray. We used microarrays to identify genes affected by Jmjd1c knockdown in mouse ESCs.
