CCL8 and cervical carcinoma: TCGA data analysis showed that the increased expression levels of ZEB1 and CCL8 were correlated with poor prognosis in human cervical cancer (Fig. 6a, b, P = 0.0335, P = 0.0019, respectively), which further suggested that ZEB1 and CCL8 may play oncogenic roles in the progression and development of cervical cancer.
