PARP-1 regulation of alternative splicing


ABSTRACT: To address the global impact of PARP-1 on alternative splicing, we isolated total RNA in two biological replicates from control (non-treated), PARP-1 siRNA- and PJ-34-treated cells. Sequencing of these RNAs on an Illumina HiSeq 2500, yielded >56 million 100-bp paired-end RNA-seq reads. First we tested if PARP-1 KD was effective at the RNA-seq level. Read aligning to the entire gene body of PARP-1 shown a reduction in PARP-1 expression of about 1.5-fold (P-value < 0.0003), confirming that indeed PARP-1 was depleted after PARP-1 siRNA treatment. We next used these RNA-seq data sets (control, PARP-1 KD and PARylation inhibited) to assess whether these treatments resulted in changes in i) gene expression and ii) alternative splicing.
