Abstract:
Objective To investigate the inhibitory effect of transforming growth factor (TGF) -β1 on oral squamous cell carcinoma (OSCC) Tb cell line.Methods Cell counting method was used to examine the inhibitory effect of TGF-β1 on Tb cell and flow cytometry(FCM) assay performed to measure the changes of cell cycle.Superarray was used to screen the changing expression of genes in TGF-β1/Smads signaling pathway.RT-PCR method was used to detect the results of Superarray.Results TGF-β1 showed significant inhibiting effect on OSCC Tb cell line.TGF-β1 blocked the cell cycle at G1 phase.The expression level of activin receptor-like kinase -1 (ACVRL-1),anti-mullerian hirmine (AMH),cyclim-dependent kinase inhibitor-2B (CDKN-2B) and transforming growth factor-beta-indnced factor(TGIF) was higer in the cells treated with TGF-β1 than in control,while TDGF-1 expression was down-regulated.ACVRL-1 and CDKN-2B gene expression was consistent with the results of Superarray.Conclusions TGF-β1 can inhibit the growth of OSCC Th cell line.The mechanism may be related to the regulation of cell cycle and the expression of ACVRL-I and CDKN-2B in TGF-β1-Smads signaling pathway.
