P19 neuronal cell differentiation


ABSTRACT: We comprehensively investigated the neural-splicing using P19 cells, set up nine filtering conditions, and obtained 262 candidate exons (236 genes). Results of semi-quantitative RT-PCR in randomly selected 30 candidates suggested that 87% of the candidates were actually changed more than double compared with the undifferentiated and differentiated cells. GO analysis and pathway analysis also showed that these 236 candidate genes were highly involved in the neural events. These results suggested that our extraction of alternative exons was quite reasonable and successful. We have biological duplicates in this project. We essentially compared Day 7 (neural-differentiated) against Day0 (Undifferentiated)

<h4>Background</h4>Alternative splicing, which produces multiple mRNAs from a single gene, occurs in most human genes and contributes to protein diversity. Many alternative isoforms are expressed in a spatio-temporal manner, and function in diverse processes, including in the neural system.<h4>Methodology/principal findings</h4>The purpose of the present study was to comprehensively investigate neural-splicing using P19 cells. GeneChip Exon Array analysis was performed using total RNAs purified  ...[more]
