Abstract:
Objective To investigate the antitumor effect of flavopiridol in ovarian cancer. Methods After the treatment with flavopiridol of AO cells,cell apoptotic rate and cell cycle distribution were detected by flow eytometer and the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labelling(TUNEL).Real time PCR was used to detect the expression of cyclin D and active caspase-3 in AO cells.Subcutaneous tumor models and abdominally spread tumor models of human ovarian carcinoma using AO ceils in BALB/c nude mice were established.The mouse survival rates were measured for abdominally spread tumor models and the volume of tumor nodules was determined for subcutaneous tumor models following the treatments of flavopiridol.TUNEL was used to detect cell apoptosis,and immunohistochemistry was used to measure microvessel density(MVD)in tumor tissues. Results AO cells showed apoptotic rates of 4.1%,10.7% and 7.6% following the treatments with flavopiridol at 150,300 and 500 nmol/L respectively,accompanied by an increase in G_1 progression and a decrease in S phase progression.The level of active caspase-3 increased(2.55 vs 2.49)and the level of cyclin D expression decreased significantly(0.25 vs 0.69,P
