We showed that four miRNAs (miR-502, miR-145, miR-142, and miR-33b) are independent and common prognostic biomarkers for patients with cervical cancer, and seven proteins (CXCL12, IGF1, PTPRC CDH5, RAD51B, REV3L, and WDHD1) are key genes significantly related to lymph node metastasis. This evidence concerns the gene WDHD1 and cervical carcinoma.
