【Abstract】　Objective　 To observe the effects of advanced glycosylation end products (AGE) on proliferation of SW-480 cells and study the possible mechanism.　Methods　 Various concentrations of AGE were designed to have impact on SW-480 cells. Proliferation of SW-480 cells was assessed by thiazolyl blue tetrazolium bromide (MTT) assay; The impact of AGE on the cell cycle of SW-480 cells was analyzed by flow cytometry (FCM); the influence of AGE on expression of CyclinD1 was checked by Western blotting; and the impact of AGE on telomerase activity was examined by telomeric repeat amplification proctol (TRAP) sliver staining. For the MTT assay, blank control group, 100 μg/mL bovine serum albumin (BSA) group, 50, 100 and 500 μg/mL AGE groups were designed, while for other examinations, there were only 100 μg/mL BSA group and 100 μg/mL AGE group.　Results　 MTT result showed that AGE increased the proliferation of SW-480 cells in a dose-dependent mode. The proportion of the cells at G0/G1 stage of the 100 μg/mL BSA group and the 100 μg/mL AGE experimental group were (56.02±0.58)% and (51.93±1.01)% respectively after 72 hours, with a significant difference (P lt;0.05); western blotting showed that the expression of CyclinD1 in the 100 μg/mL AGE group was significantly higher than that in the 100 μg/mL BSA group after 72 hours; TRAP silver staining demonstrated that telomerase activity increased significantly after treated with 100 μg/mL AGE for 72 hours.　Conclusions　 AGE can promote the growth of SW-480 cells in a dose-dependent mode. Its mechanism is mainly by up-regulating the expression of CyclinD1 to shorten G0/G1 and increasing the telomerase activity significantly.
