Impact of splicing factors (ESRP1 and KHDRBS3) on prostate cancer biology


ABSTRACT: Dysregulation of mRNA alternative splicing (AS) has been implicated in development and progression of hematological malignancies. How the global AS dysregulation contributes to the development and progression of solid tumors remains generally unclear. Recently, we show that many splicing factors (such as ESRP1 and KHDRBS3) are overexpressed in human primary prostate cancer (PCa) versus normal tissues. To further determine the biological impact of splicing factors on PCa aggressiveness, we treated AR- PC3 cells with siRNAs against either ESRP1 or KHDRBS3 and both. RNA-seq analysis was done in triplicates of rRNA-depleted total RNAs isolated from PC3 cells 48-72hr after siRNA infection. rMATS and DEseq2 were used to reveal the effect of knocking down ESRP1 and/or KHDRBS3 individually or in combination on mRNA splicing landscape and gene expression change.
