To further validate that the hub genes that are significantly associated with CC prognosis is indeed differentially expressed between normal cervical tissues and CC tissues, GEPIA, a web server for cancer and normal gene expression profiling and interactive analyses, was applied for further confirmation of the expression level of the 6 hub genes (PLOD2, ANLN, AURKA, HOPX, AR, and KRT4) between cancerous and normal tissues. Here, AURKA is linked to cancer.
