FOXA1 regulates splicing-related gene expression and alternative splicing in prostate cancer cells
Dysregulation of alternative splicing in prostate cancer is linked to transcriptional programs activated by canonical oncogenic transcription factors. However, the relative contribution of these factors to alternative splicing regulation is yet to be defined. We investigated the role of FOXA1 by performing deep RNA-seq on siRNA-treated (i.e. siFOXA1) and control (i.e. NSI) samples from prostate cancer cell lines. Using this data, we performed canonical parametric differential expression analysis between NSI and siFOXA1 samples to determine the effect of FOXA1 depletion on splicing related gene expression. We also identified FOXA1-regulated differentially alternatively spliced exons between NSI and siFOXA1 samples. Overall design: 12 total samples, 3 replicates per condition.
