The Inhibition of Antisense TRPl in the Proliferation of Malignant Melanoma Cells in vivo and in vitro / 中国肿瘤生物治疗杂志

Objective: To study the inhibition of antisense TRP1 on cell growth of malignant melanoma(MM) and explore a new way for therapy of melanoma. Methods: Antisense TRP-1 recombinant vector was constructed and transfected into MM cells. According to the results of MTT, cell growth curves were drawn and then clonogenic assay was performed in vitro. At last, tumorigenesis assay was undertaken in nude mice in vivo. Results: Cell proliferations of TRP-1 transfected MM cells were inhibited compared with the control cells. The results of clonogenic assay displayed the difference of clonogenic percentage between TRP-1 transfected MM cells (52% , P
