摘要
目的探讨转化生长因子β受体(TGF-βR)Ⅰ、Ⅱ型在皮肤黑色素瘤细胞中的表达情况。方法应用反转录-实时荧光定量PCR(RT-PCR)和蛋白免疫印迹(Western blot)方法,对TGF-βRⅠ、Ⅱ型的mRNA及其蛋白在人皮肤黑色素瘤A375细胞和人正常黑素细胞中的表达进行检测。结果 A375细胞中TGF-βRⅠ、Ⅱ型的mRNA和蛋白表达均显著低于正常人黑素细胞。结论在黑色素瘤细胞的TGF-β/Smad信号通路中出现TGF-βR表达的下调,可能是皮肤黑色素瘤发病机制之一。
Objective To investigate the expression and significance of TGF‐β receptor Ⅰ /TGF‐β receptor Ⅱ (TGF‐β Ⅰ /TGF‐β Ⅱ) in human skin malignant melanoma A375 cell line .Methods The reverse transcription‐real time polymerase chain reac‐tion (RT‐PCR) and Western blot were utilized to assess the expressions of TGF‐βR Ⅰ /TGF‐‐βR Ⅱ in A375 cell line and human normal melanocytes .Results The expressions of TGF‐βR Ⅰ /TGF‐‐βR Ⅱ mRNA and protein of A375 cells line were significantly lower than those of human normal melanocytes .Conclusion The down‐regulated expression of TGF‐βR in the TGF‐β/Smad signal pathway of human skin malignant melanoma may be one of the pathogenesis of skin malignant melanoma .
