Abstract:
Objective To investigate the effect of tripterygium on the grow th ,invasion and angiogenesis of melanoma A375 and its action mechanisms .Methods MTS was used to test the effect of tripterygium on proliferation of A375 melanoma;the nude mouse subcutaneous melanoma xenograft model was used to detect the effect of tripterygium on tumor growth ;the Transwell ex‐periment was used to determine the effect of tripterygium on invasion of A 375 melanoma;the tubule formation experiment was used to determine the effect of tripterygium on tumor angiogenesis ;ELISA was used to detect the influence of tripterygium on A 375 cel‐lular secretion factors ,such as VEGF ,bFGF ,TGF‐βand IL‐8 .Results The in vitro proliferation and in vivo growth of A375 mela‐noma cells after tripterygium treatment were significant inhibited ,the invasion ability of A375 melanoma cells was significant weak‐ened compared with the control group ;tripterygium could inhibit tumor cell‐induced vessel formation by down‐regulating the ex‐pression of VEGF ,bFGF and IL‐8 proteins ,but it had no influence on expression of TGF‐βprotein .Conclusion Tripterygium has anti‐growth and anti‐invasion effects on A375 melanoma ,its potential mechanisms may associated with the inhibition of tumor an‐giogenesis of A375 melanoma .
