(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) The direct conversion of human skin fibroblasts to neurons has a low efficiency and unclear mechanism. Here, we show that the knockdown of PTBP2 (nPTB) significantly enhanced the transdifferentiation induced by ASCL1, MiR124-9/9* and p53 shRNA to generate mostly GABAergic neurons. Longitudinal RNAseq analyses identified the continuous induction of many RNA Splicing Regulators (RSRs). Among these, the knockdown of RBFOX3, which encodes the mature neuronal marker NeuN, significantly abrogated the transdifferentiation. 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) 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) The splicing regulator PTBP2 controls a program of embryonic splicing required for neuronal maturation. The splicing regulatory proteins PTBP1 and PTBP2 show distinct temporal expression profiles in the developing brain. Neuronal progenitor cells predominantly express PTBP1, whereas developing neurons express high levels of PTBP2, which are subsequently reduced late in neuronal maturation. We show here that PTBP2 and the program of splicing it controls are essential to proper neuronal maturation and survival. 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...
