PCBP1 and ovarian carcinoma: To further investigate the role of PCBP1 in ovarian cancer, we retrieved the transcriptional profiles of an independent ovarian cancer dataset containing 30 tumors of low malignant potential and 60 serous ovarian cancer tumor samples [28] available at Gene Expression Omnibus (http://www.ncbi.nlm.nih.gov/geo/; accession no. GSE12172).
