HK2 and cervical carcinoma: To further investigate the function of HK2 in human cervical cancer cells, exogenous HK2 was stably overexpressed in SiHa (SiHa-HK2, Figure 1H) and HeLa (HeLa-HK2, Figure 1I) cells; conversely, endogenous expression of HK2 was knocked down by stably transfecting shRNA plasmids in SiHa (SiHa-shHK2, Figure 1J) and HeLa (HeLa-shHK2, Figure 1K) cells.
