Moreover, HK2 expression was observed in ovarian cancer cell lines (OVCA433, A2780 and SKOV3) using immunocytochemistry (Figures 1D) and western blotting (Figures 1E), and a relatively low expression of HK2 was observed in OVCA433 and SKOV3 cells. The gene discussed is HK2; the disease is ovarian carcinoma.
