To thoroughly investigate the mechanism of PCBP1 against tumor formation, we adopted a strategy to capture all PCBP1-bound mRNAs by crosslinking PCBP1 to RNA molecules and immunoprecipitating them for sequencing identification (indicated as RIP-seq) in human ovarian cancer A2780 cells (Additional file 3: Figure S1A). This evidence concerns the gene PCBP1 and ovarian carcinoma.
