Alternative splicing is frequent during early embryonic development in mouse

Project description:Background Alternative splicing is known to increase the complexity of mammalian transcriptomes since nearly all mammalian genes express multiple pre-mRNA isoforms. However, our knowledge of the extent and function of alternative splicing in early embryonic development is based mainly on a few isolated examples. High throughput technologies now allow us to study genome-wide alternative splicing during mouse development. Results A genome-wide analysis of alternative isoform expression in embryonic day 8.5, 9.5 and 11.5 mouse embryos and placenta was carried out using a splicing-sensitive exon microarray. We show that alternative splicing and isoform expression is frequent across developmental stages and tissues, and is comparable in frequency to the variation in whole-transcript expression. The genes that are alternatively spliced across our samples are disproportionately involved in important developmental processes. Finally, we find that a number of RNA binding proteins, including putative splicing factors, are differentially expressed and spliced across our samples suggesting that such proteins may be involved in regulating tissue and temporal variation in isoform expression. Using an example of a well characterized splicing factor, Fox2, we demonstrate that changes in Fox2 expression levels can be used to predict changes in inclusion levels of alternative exons that are flanked by Fox2 binding sites. Conclusions We propose that alternative splicing is an important developmental regulatory mechanism. We further propose that gene expression should routinely be monitored at both the whole transcript and the isoform level in developmental studies. 25 samples were analyzed. Developmental stages e8.5, e9.5 and e11.5 (embryos from all 3, placenta for only e9.5 and e11.5). 5 biological replicates for each.

Next-generation sequencing identifies mRNAs targets that experience significant changes in alternative splicing upon PQBP1 knockdown in mouse embryonic cortical neurons

Project description:PQBP1 is a highly conserved protein closely related to neurodegenerative disorders. We identified PQBP1 as an important alternative splicing effector necessary for maintaining normal neuron functions in the brain. In order to explore PQBP1's functions in alternative splicing regulation and neuronal activities, we systematically profiled the alternative splicing targets of PQBP1 in mouse embryonic cortical neurons by RNA-seq. The mRNAs whose alternative splicing are affected by PQBP1 showed tissue-specific functional enrichment especially in neurite outgrowth, with strong Gene Ontology (GO) enrichments for neuron projection development/morphogenesis, dendrite development and axonogenesis. PQBP1's alternative splicing targets are also functionally enriched in RNA splicing, chromatin modification, and ARF signal transduction. We applied RNA-seq to compare the transcriptomes of mock and PQBP1 knockdown mouse embryonic cortical neuron samples.

Expression data from mouse embryonic fibroblasts and pluripotent stem cells

Project description:Splicing profiles in pluripotent stem cells are different from those in somatic cells. Generally, alternative splicing is regulated by RNA binding proteins. To identify the candidate RNA-binding protein-encoding genes, we performed gene expression profiling experiments. Expression levels were profiled in mouse embryonic fibroblasts (MEFs), 2 iPS cell lines (492B4, 178B5), and ES cells (v6.5).

Muscleblind-like proteins regulate embryonic stem cell-specific alternative splicing and reprogramming I

Project description:Previous investigations of the core gene regulatory circuitry that controls embryonic stem cell (ESC) pluripotency have largely focused on the roles of transcription, chromatin and non- coding RNA regulators. Alternative splicing (AS) represents a widely acting mode of gene regulation, yet its role in the regulation of ESC pluripotency and differentiation is poorly understood. Here, we identify the Muscleblind-like RNA binding proteins, MBNL1 and MBNL2, as conserved and direct negative regulators of a large program of AS events that are differentially regulated between ESCs and other cell types. Knockdown of MBNL proteins in differentiated cells causes switching to an ESC-like AS pattern for at least half of these AS events. Among the events is an ESC-specific AS switch in the forkhead family transcription factor FOXP1 that controls pluripotency. Consistent with a central and negative regulatory role for MBNL proteins in pluripotency, their knockdown significantly enhances the expression of key pluripotency genes and the formation of induced pluripotent stem cells (iPSCs) during somatic cell reprogramming. mRNA profiles of various embryonic stem cells, tissues and cell lines from human and mouse using high-throughput sequencing data and the role of MBNL proteins in regulation of ESC-differential alternative splicing
