摘要: 目的 应用Dicer1(编码蛋白属于RNA酶III家族)转基因小鼠建立黑色素瘤模型。方法 将小鼠黑色素瘤细胞株分别移植于Dicer1转基因鼠和C57BL/6J小鼠前肢腋下,观察两种小鼠的荷 瘤情况,包括移植瘤生长情况、移植瘤生长曲线。结果 与C57BL/6J小鼠组肿瘤比较,Dicer1转基因小鼠组的肿瘤成瘤时间短、肿瘤生长速度快、肿瘤体积大( P<0.05)。结论 应用Dicer1转基因小鼠建立了黑色素瘤模型,结果显示 Dicer1基因对黑色素瘤荷瘤有明显影响。

Abstract: Objective To establish a model of B16 melanoma model in Dicer1 transgenic mice. Methods B16 melanoma cell were subcutaneously implanted into Dicer1 transgenic and C57BL/6J mice, the morphology and growth velocity of the tumor were observed. Result Compared with the contrast group, the tumor formation time in Dicer1 transgenic mice is shorter, the tumor growth rate is faster, the tumor volume is bigger (P<0.05). Conclusion The model of B16 melanoma model was successfully established in transgenic mice and the Dicer1 had significant effects on B16 melanoma bearing of mice.
