UHRF1 promotes melanoma progression by inducing cell proliferation, and is correlated with poor prognosis of melanoma patients. However, the regulation mechanism has not been fully elaborated. Here, we detected hsa-let-7b expression and its role in melanoma. Through Targetscan and miRanda predication, 30 overlapped miRNAs were found; further survival analysis revealed that hsa-let-7b was the only miRNA that affected the overall survival. Overexpressed hsa-let-7b could significantly inhibit the proliferation ability of A375 and A2058 cells, and this phenomenon was reversed after co-transfection with pLenti-UHRF1. In conclusion, hsa-let-7b regulates melanoma cells proliferation by targeting UHRF1.
UHRF1 通过诱导细胞增殖促进黑色素瘤的进展，并与黑色素瘤患者的不良预后相关。然而，其调控机制尚未充分阐述。在这里，我们检测了 hsa-let-7b 的表达及其在黑色素瘤中的作用。通过 Targetscan 和 miRanda 预测，发现了 30 个重叠的 miRNA；进一步的生存分析表明，hsa-let-7b 是唯一影响总生存期的 miRNA。过表达 hsa-let-7b 可显著抑制 A375 和 A2058 细胞的增殖能力，而与 pLenti-UHRF1 共转染后这种现象被逆转。综上所述，hsa-let-7b 通过靶向 UHRF1 调节黑色素瘤细胞的增殖。
