Identification of PRMT5 as a Diagnosis Biomarker for Cervical Cancer by Bioinformatics Analysis

Cervical cancer (CC) is the fourth most common cancer among women worldwide. Early screening is helpful for the diagnosis and precision treatment of cervical cancer. Therefore, identification of CC related protein markers is required for cervical cancer diagnosis. In this study, we found the protein arginine N-methyltransferase 5 (PRMT5) was upregulated in CC patients compared with normal tissues through analysis of data from TCGA and GTEx datasets. Immunohistochemical staining and western blot confirmed that PRMT5 was indeed increased in the CC tissues. Furthermore, PRMT5 enhanced the ability of cell clone formation through activating AKT signaling pathway. Taken together, the higher expression of PRMT5 in the CC may be act as a prognostic biomarker, which involved in carcinogenesis by excessively activating AKT signaling pathway.
