Moreover, HK2 expression was observed in all five cervical cancer cell lines using western blotting and immunocytochemistry (HeLa, SiHa, C-33 A, CaSki, and HT-3, Figures 1F, E), and a relatively low expression of HK2 was observed in HeLa and SiHa cells. This evidence concerns the gene HK2 and cervical carcinoma.
