(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) PTBP1 and PTBP2 are RNA-binding proteins that control RNA processings, including alternative pre-mRNA splicing. The sequential down-regulation of the two proteins is necessary for neuronal maturation. However, their binding substrates in neural tissues have not been examined.

(Submitter supplied) To determine targets of PTBP2-dependent alternative splicing, we depleted PTBP2 in human neurons derived from induced-pluripotent stem cells (iPSC-neurons) using an LNA gapmer and performed RNA-seq on untreated, negative control-treated, and knock-down samples.

(Submitter supplied) To determine direct targets of PTBP2-dependent alternative splicing, we performed CLIP-seq analysis of PTBP2 binding in both human cortical tissue and human neurons derived from induced-pluripotent stem cells (iPSC-neurons), and we combine this with splicing analysis following PTBP2 depletion in iPSC-neurons.

(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) Alternative RNA splicing is an essential and dynamic process in neuronal differentiation and synapse maturation, and dysregulation of this process has been associated with neurodegenerative diseases. Recent studies have revealed the importance of RNA-binding proteins in the regulation of neuronal splicing programs. However, the molecular mechanisms involved in the control of these splicing regulators are still unclear. 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) 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) How a neuron acquires an axon is a fundamental question. Piecemeal identification of many axonogenesis-related genes has been done, but coordinated regulation is unknown. Through unbiased transcriptome profiling of immature primary cortical neurons during early axon formation, we discovered an association between axonogenesis and neuron-specific alternative splicing. Known axonogenesis genes exhibit little expression alternation but widespread splicing changes. 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...
