(Submitter supplied) Alternative splicing regulates over 90% of multiexon mammlian genes, but its role in specifying neural progenitor cell (NPC) fates has not been explored. Our analyses of purified mouse NPCs and neurons from developing cerebral cortices revealed hundreds of conserved and differentially spliced exons that add or remove key protein domains, especially in genes regulating the cytoskeleton.

(Submitter supplied) Alternative splicing (AS) generates extensive transcriptomic and proteomic complexity. However, the functions of species- and lineage-specific splice variants are largely unknown. Here, we show that mammalian-specific skipping of exon 9 of PTBP1 alters its splicing regulatory activities and affects the inclusion levels of numerous exons. During neurogenesis, skipping of exon 9 reduces PTBP1 repressive activity so as to facilitate activation of a brain-specific AS program. more...

(Submitter supplied) Both microRNAs and alternative pre-mRNA splicing have been implicated in the development of the nervous system (NS), but functional interactions between these two pathways are poorly understood. We demonstrate that the neuron-specific microRNA miR-124a directly targets PTBP1/PTB/hnRNPI mRNA, which encodes a global repressor of alternative pre-mRNA splicing in non-neuronal cells. Among the targets of PTBP1 is a critical cassette exon in the pre-mRNA of PTBP2/nPTB/brPTB, an NS-enriched PTBP1 homolog. more...

(Submitter supplied) PTBP1 and PTBP2 control alternative splicing programs during neuronal development, but the cellular functions of most PTBP1/2-regulated isoforms remain unknown. We show that PTBP1 guides developmental gene expression by regulating the transcription factor Pbx1. We identify exons that are differentially spliced when mouse embryonic stem cells (ESCs) differentiate into neuronal progenitor cells (NPCs) and neurons, and transition from PTBP1 to PTBP2 expression. more...

(Submitter supplied) Two polypyrimidine tract RNA-binding proteins (PTBs), one near-ubiquitously expressed (Ptbp1) and another highly tissue-restricted (Ptbp2), regulate RNA in interrelated but incompletely understood ways. Ptbp1, a splicing regulator, is replaced in the brain and differentiated neuronal cell lines by Ptbp2. To define the roles of Ptbp2 in the nervous system, we generated two independent Ptbp2-null strains, unexpectedly revealing that Ptbp2 is expressed in neuronal progenitors and is essential for postnatal survival. more...

(Submitter supplied) While thousands of long noncoding RNAs (lncRNAs) have been identified, few lncRNAs that control neural stem cell (NSC) behavior are known. Here, we identify Pinky (Pnky) as a novel, neural-specific lncRNA that regulates neurogenesis from NSCs in the embryonic and postnatal brain. In postnatal NSCs, Pnky knockdown potentiates neuronal lineage commitment and expands the transit-amplifying cell population, increasing neuron production several-fold. more...

(Submitter supplied) We sequenced mRNA from mouse E14.5 embryonic cortex to compare gene expression level and alternative splicing events between 2 control (WT) and 2 Qk cKO. A set of tissue specific splicing factors are thought to govern alternative splicing events during neural progenitors (NPC) to neuron transition by regulating neuron specific exons. Here we proposed one such a factor, RNA-binding protein Qki5, which is specifically expressed in neural stem cells. more...

(Submitter supplied) Maintenance of embryonic stem cells (ESCs) and their differentiation to neuronal lineages requires complex genetic regulation of transcription, splicing, and translation, but the interconnections of these processes is not well understood. We found that the splicing regulator polypyrimidine tract binding protein 1 (PTBP1) alters the neuronal transcriptional program. Transcripts for DPF2, a subunit of the BRG1/BRM-associated factor (BAF) chromatin remodeling complex, contain an additional exon (exon 7) in brain. more...
