CXCL10 and cervical cancer: CXCL10 expression was determined by western blotting of HFF-1 (HPV- human epithelial foreskin fibroblasts cells), H8 (HPV+, cervical immortalized cells), SiHa (HPV+, cervical cancer cells), KoE6/E7 SiHa (HPV-E6E7 knockout cells) and the results showed that the expression of CXCL10 was greater in HPV+ compared to HPV-cell lysates (Figure 2C).
