Next generation sequencing to determine alternative cleavage and polyadenylation events among prostate and prostate cancer cell lines


ABSTRACT: Alternative cleavage and polyadenylation (APA) is a form of transcriptional regulation via shifts in how frequently multiple polyadenylation (polyA) sites within genes are used across biological conditions. APA can result in transcripts with varying length and information content, and has been linked to gene regulation in both cancer and development. To provide a reference for investigating APA in the context of prostate cancer, we performed a genome-wide quantification of polyA site usage using a next generation sequencing technique. By priming the polyA-tails of an RNA library, we mapped cleavage sites and abundances with base-pair resolution across the genomes of one normal prostate and two prostate cancer cell lines. This data can be used to detect APA events among these cell line models, and integration of these data with APA events from clinical prostate cancer samples can lead to candidate genes for future mechanistic studies of the regulation and function of APA in cancer.
