To produce the scientific evidence for developing and manufacturing new antitumor drugs.Methods: 1 The inhibitory effect on cell growth of Hela was measured by MTT assay in treated or untreated groups (3.125, 6.25, 12.5, 25, 50μg/ml TAM and control) for three different treatment times (24h, 48h and 72h).2 Apoptosis and cell cycle were measured by FCM in four experimental groups (0, 4, 16, 40μg/ml TAM) for 48h.3 Adopting Wright and Giemse's staining to observe the morphology of Hela cells which treated with 40μg/ml TAM.4 Using invasion experiment to detect the Hela cells'invasive abilities which treated with 40μg/ml TAM.5 The protein expressional levels of P-ERK, ERK, C-myc and Cyclin D1 in Hela cells untreated or treated with 4, 16, 40μg/ml TAM for 24h were measured by Western blot.6 Expression of anti-apoptotic gene bcl-2, apoptotic gene bax and MMP-9 in Hela cells of four experimental groups (0, 4, 16, 40μg/ml TAM for 24h), were observed by revers transcription PCR.7 The protein expression of P-ERK, ERK, Bcl-2 and Bax in Hela cells treated with 40μg/ml TAM for 24h observed by laser scanning microscopes.
