Transcription pausing regulates mouse embryonic stem cell differentiation.

Project description:The pluripotency of embryonic stem cells (ESCs) relies on appropriate responsiveness to developmental cues. Promoter-proximal pausing of RNA polymerase II (Pol II) has been suggested to play a role in keeping genes poised for future activation. To identify the role of Pol II pausing in regulating ESC pluripotency, we have generated mouse ESCs carrying a mutation in the pause-inducing factor SPT5. Genomic studies reveal genome-wide reduction of paused Pol II caused by mutant SPT5 and further identify a tight correlation between pausing-mediated transcription effect and local chromatin environment. Functionally, this pausing-deficient SPT5 disrupts ESC differentiation upon removal of self-renewal signals. Thus, our study uncovers an important role of Pol II pausing in regulating ESC differentiation and suggests a model that Pol II pausing coordinates with epigenetic modification to influence transcription during mESC differentiation.

Transcription Pausing Regulates Mouse Embryonic Stem Cell Differentiation [GRO-seq]

Project description:The pluripotency of embryonic stem cells (ESCs) relies on appropriate responsiveness to developmental cues. Promoter-proximal pausing of RNA polymerase II (Pol II) has been suggested to play a role in keeping genes poised for future activation. To identify the role of Pol II pausing in regulating ESC pluripotency, we have generated mouse ESCs carrying a mutation in the pause-inducing factor SPT5. Consistent with previous in vitro studies showing the pausing deficiency of this mutant SPT5, our genomic analysis reveals genome-wide reduction of paused Pol II in mutant mESCs. Furthermore, we find that genes differentially regulated by mutant SPT5 correlates with distinct chromatin states. Functionally, this pausing-deficient SPT5 disrupts ESC differentiation without affecting self-renewal. Thus, our study uncovers an important role of Pol II pausing in regulating ESC differentiation and also suggests that Pol II pausing can both positively and negatively influence transcription depending on the local chromatin environment.

Fezf2 regulates telencephalic precursor differentiation from mouse embryonic stem cells.

Project description:The mechanisms by which transcription factors control stepwise lineage restriction during the specification of cortical neurons remain largely unknown. Here, we investigated the role of forebrain embryonic zinc finger like (Fezf2) in this process by generating Fezf2 knockdown and tetracycline-inducible Fezf2 overexpression mouse embryonic stem cell (mESC) lines. The overexpression of Fezf2 at early time points significantly increased the generation of rostral forebrain progenitors (Foxg1(+), Six3(+)) and inhibited the expression of transcription factors which are expressed by the midbrain and caudal diencephalon (En1(+), Irx(+)). This effect was partially achieved by the regulation of Wnt signaling during this critical early time window. The role of Fezf2 in regulating the rostrocaudal patterning was further confirmed by the significant decrease in the expression of Foxg1 and Six3 and the increase in the expression of En1 when Fezf2 was knocked down. In addition, Fezf2 overexpression at later time points had little effect on the expression of Foxg1 and Six3. Instead, Fezf2 promotes the generation of dorsal telencephalic progenitors and deep-layer cortical neurons at later stages. Collectively, our data suggest that Fezf2 controls the specification of telencephalic progenitors from mESCs through differentially regulating the expression of rostrocaudal and dorsoventral patterning genes.

Alternative splicing regulates mouse embryonic stem cell pluripotency and differentiation.

Project description:Two major goals of regenerative medicine are to reproducibly transform adult somatic cells into a pluripotent state and to control their differentiation into specific cell fates. Progress toward these goals would be greatly helped by obtaining a complete picture of the RNA isoforms produced by these cells due to alternative splicing (AS) and alternative promoter selection (APS). To investigate the roles of AS and APS, reciprocal exon-exon junctions were interrogated on a genome-wide scale in differentiating mouse embryonic stem (ES) cells with a prototype Affymetrix microarray. Using a recently released open-source software package named AltAnalyze, we identified 144 genes for 170 putative isoform variants, the majority (67%) of which were predicted to alter protein sequence and domain composition. Verified alternative exons were largely associated with pathways of Wnt signaling and cell-cycle control, and most were conserved between mouse and human. To examine the functional impact of AS, we characterized isoforms for two genes. As predicted by AltAnalyze, we found that alternative isoforms of the gene Serca2 were targeted by distinct microRNAs (miRNA-200b, miRNA-214), suggesting a critical role for AS in cardiac development. Analysis of the Wnt transcription factor Tcf3, using selective knockdown of an ES cell-enriched and characterized isoform, revealed several distinct targets for transcriptional repression (Stmn2, Ccnd2, Atf3, Klf4, Nodal, and Jun) as well as distinct differentiation outcomes in ES cells. The findings herein illustrate a critical role for AS in the specification of ES cells with differentiation, and highlight the utility of global functional analyses of AS.
