EPPK1 and cervical carcinoma: Because Eppk1 is a part of EGFR, and Eppk1 expression has a positive correlation with EGFR in CC from TCGA data (P < 0.05, R = 0.13) (Fig. 5a), we further clarify the EGFR-related signaling pathways by which Eppk1 expression affects the proliferation of cervical cancer cells.
