To explore the role of F10 gene in regulating cell cycles of choriocarcinoma cells and the underlying mechanisms.Using untreated cells as the control, JAR cells with F10 gene silencing or stable F10 over-expression were examined for cell cycle changes by flow cytometry (FCM) and for expressions of cyclin and cyclin-dependent kinase (CDKs) with Western blotting and immunofluorescence technique.JAR cells over-expressing F10 gene showed reduced duration of cell cycle compared with untreated and with cells after F10 gene silencing. In F10-over-expressing cells, Western blotting revealed significantly up-regulated expressions of cyclin A2, B1, D1, E and CDK2, 6, and 7, but not CDK4, as compared with the control cells and cells with F10 gene silencing (P0.05), and these results were consistent with those by immunofluorescence assay.F10 gene may accelerate cell cycle progression and promote cell proliferation by up-regulating the expressions of cyclin A2, B1, D1, E and CDK 2, 4, 6, 7 in choriocarcinoma cells. |
