ABSTRACT
Objective To explore the effects of bacailin on the angiogenic regulating factor and migration activity of laryngeal cancer cells.Methods Hep-2 was cultured in vitro,(1)in the groups adding phorbol ester,gelatin-zymogram and Transwell assay were used to observe the effects of bacailin on the gelatinase activity of matrix metalloproteinase (MMP) and the migration ability of Hep-2,respectively; (2)in the group without phorbol ester,enzyme-linked immunosorbent assay (ELISA) was used to detect the effects of bacailin on the protein level of endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF).Results Among the control group,the low-dose group,the middle-dose group,and the high-dose group,the activity of MMP-3 of each corresponding group was (100.0 ±0.0) ％,(95.0 ±4.9) ％,(93.1± 6.2)％,and (90.7 ± 7.3)％ with statistically significant difference (t =2.123,2.309,2.412,P ＜0.05) ; the activity of MMP-9 of each corresponding group was (100.0 ± 0.0) ％,(92.3 ± 7.5) ％,(89.5 ± 9.3) ％,and (85.6 ± 6.1) ％ with statistically significant difference (t =2.253,2.302,3.708,P ＜0.05 or P ＜0.01) ;the protein level of VEGF of each corresponding group was (242.7 ±9.5)ng/L,(230.6 ± 12.7)ng/L,(212.1 ± 15.9)ng/L,and (184.2 ± 23.5)ng/L with statistically significant difference (t =2.408,3.733,4.146,P ＜0.05 or P ＜0.01) ; the protein level of bFGF of each corresponding group was (190.7±8.2) ng/L,(181.2±13.0) ng/L,(169.9±17.3)ng/L,and (140.7±9.2)ng/Lwith statistically significant difference (t =2.330,2.922,5.145,P ＜0.05 or P ＜0.01) ; Cellular migration rate of each corresponding group was (38.3 ± 5.6) ％,(32.9 ± 7.1) ％,(27.9 ± 4.4) ％,and (23.3 ± 6.0) ％ with statistically significant difference (t =2.141,3.365,4.027,P ＜ 0.05 or P ＜0.01).Conclusions Bacailin could suppress the migration of Hep-2 through inhibiting expression of angiogenic regulating factor,which might has clinical value in the treatment of laryngeal cancer.
