Abstract

Localized prostate cancer can be cured by radiation or surgery, but advanced prostate cancer continues to be a clinical challenge. Altered alternative polyadenylation occurs in numerous cancers and can downregulate tumor-suppressor genes and upregulate oncogenes. We found that the cleavage and polyadenylation specificity factor (CPSF) complex factor CPSF1 is upregulated in patients with advanced prostate cancer, with high CPSF1 expression correlating with worse progression-free survival. Knockdown of CPSF1 selectively inhibited the growth of prostate cancer cells and reduced glycolytic output. Evaluating the changes in global poly(A) site usage in prostate cancer cells following CPSF1 knockdown revealed widespread usage of intergenic poly(A) sites distal to annotated 3' UTRs, which lengthened 3' UTRs and decreased levels of thousands of mRNAs, including key glycolysis genes. These findings uncover a role for CPSF1 in the suppression of intergenic poly(A) sites in prostate cancer and nominate CPSF1 as a therapeutic target in advanced prostate cancer.

期刊介绍： Cell Reports publishes high-quality research across the life sciences and focuses on new biological insight as its primary criterion for publication. The journal offers three primary article types: Reports, which are shorter single-point articles, research articles, which are longer and provide deeper mechanistic insights, and resources, which highlight significant technical advances or major informational datasets that contribute to biological advances. Reviews covering recent literature in emerging and active fields are also accepted. The Cell Reports Portfolio includes gold open-access journals that cover life, medical, and physical sciences, and its mission is to make cutting-edge research and methodologies available to a wide readership. The journal's professional in-house editors work closely with authors, reviewers, and the scientific advisory board, which consists of current and future leaders in their respective fields. The advisory board guides the scope, content, and quality of the journal, but editorial decisions are independently made by the in-house scientific editors of Cell Reports.
