Project description:Mouse B cells, upon ectopic expression of the transcription factor C/EBPalpha for 18h, can be reprogrammed to induced pluripotent stem (iPS) cells with extremely high efficiency. To understand the molecular control of this phenomenon we performed a time course proteomic analysis by label-free protein quantification of proteins during B cell reprogramming to iPS cells.

Project description:<p>Gene expression is a biological process regulated at different molecular levels, including chromatin accessibility, transcription, and RNA maturation and transport. In addition, these regulatory mechanisms have strong links with cellular metabolism. Here we present a multi-omics dataset that captures different aspects of this multi-layered process in yeast. We obtained RNA-seq, metabolomics, and H4K12Ac ChIP-seq data for wild-type and mip6delta strains during a heat-shock time course. Mip6 is an RNA-binding protein that contributes to RNA export during environmental stress and is informative of the contribution of post-transcriptional regulation to control cellular adaptations to environmental changes. The experiment was performed in quadruplicate, and the different omics measurements were obtained from the same biological samples, which facilitates the integration and analysis of data using covariance-based methods. We validate our dataset by showing that ChIP-seq, RNA-seq and metabolomics signals recapitulate existing knowledge about the response of ribosomal genes and the contribution of trehalose metabolism to heat stress.</p>

Project description:We tested a genome-scale artificial transcription factor (ATF) library in reprogramming mouse embryonic fibroblasts to induced pluripotent stem (iPS) cells. Three combinations of ATFs (C2, C3, and C4) could induce pluripotency when expressed with Sox2, Klf4, and c-Myc. The transcriptional profiles of ATF-induced iPS cells are similar to that of iPS cells induced with Oct4, Sox2, Klf4, and c-Myc and mouse embryonic stem cells, exhibiting up-regulation of pluripotency markers and down-regulation of fibroblast markers. We performed ChIP-seq on the active histone mark H3K27ac and the repressive histone mark H3K9me3 in C2+SKM iPS cells, C3+SKM iPS cells, in Oct4+SKM to validate the total transcriptome results. In addition, the ATFs from C2 were chromatin immunoprecipitated to determine where they are bound in the genome at an intermediate stage before being fully reprogrammed to iPS cells. This study provides a proof-of-principle that a gene-activating ATF library can be used to identify cell fate-defining transcriptional networks in an unbiased manner.
