ABSTRACT
Objective To explore the expression of anaplastic lymphoma kinase(ALK) in human ovarian serous adenocarcinoma cell line SKOV3 and to further investigate the effect of crizotinib on SKOV3 cells.Methods The expression of ALK in SKOV3 cells were examined by Western blotting and immunocytochemical methods,and the effect of ALK inhibitor crizotinib on proliferation of SKOV3 cells were evaluated by cell proliferation assay.Results Both Western blotting and immunocytochemical methods showed the expression of ALK in SKOV3 cells.The results of cell proliferation assay suggested that the cell viability of SKOV3 cells was close to 1 when the drug concentration was less than 106 nmol·L-1,and close to 64% when the drug concentration was up to 107nmol·L-1.Conclusion ALK is overexpressed in human ovarian serous adenocarcinoma cell line SKOV3,but SKOV3 cells were insensitive to the therapy of ALK inhibitor crizotinib.
