Project description:Bcl-2-accociated transcription factor 1(BCLAF1) has been reported to be involved in diverse biological processes. Alternative splicing leads to mutiple transcript virants in human cells and we are interested in functions of its full length isoform(BCLAF1-L) in human colon cancer cells, thus to understanding its role in colon cancer progression. We used microarray to detail the global programme of gene expression after BCLAF1-L knockdown(sh-BCLAF1-L#1) in RKO cells and identified distinct classes of up-regulated or down-regulated genes impaired by its inhibition, when comparing with the control group(sh-Luci). RKO cells were infected with retroviruses either expressing control (sh-Luci) or BCLAF1-L knockdown (sh-BCLAF1-L#1). Medium was replaced 24h after infection, and infected cells were selected by the addition of puromycin (2ug/ml) for 72-96h. Then cells were havested for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Bcl-2-accociated transcription factor 1(BCLAF1) has been shown to be involved in multiple biological processes. Transcript variants encoding different isoforms that are generated by alternative splicing have been found for this gene, but little is known about the mechanisms governing its splicing regulation and whether the misregulation is associated with cancer development. Mechanistic analysis revealed that splicing factor SRSF10 specifically interacts with exon5a and activates its inclusion, as RNAi-mediated knockdown of SRSF10 induced a dramatic skipping of exon5a. To define a comprehensive programm of alternative splicing that is regulated by SRSF10 in RKO cells, we used RNA-seq coupled with a bioinformatic analysis to identify the extensive splicing network regulated by SRSF10 in RKO cells.
