Abstract
OBJECTIVE: To investigate the inhibiting effect of epidermal growth factor receptor (EGFRmAb) on proliferation of oral squamous cell carcinoma (SCC). METHODS: Tca8113 squamous cell carcinoma cell line was treated with different concentration of EGFRmAb. Cell growth curve, clone inhibition rate, cell cycle redistribution and the expression of p27kip1 were analyzed. RESULTS: EGFRmAb inhibited proliferation of oral SCC, leaded to elevation of cell proportion of G1phase cell, decreased the proportion of S phase cell and upregulated the express of p27kip1. CONCLUSION: EGFRmAb inhibited the proliferation of oral SCC, which related with G1 phase arrest of tumor cell.
