黑色素瘤是最致命的皮肤肿瘤。为了防止转移,早期诊断和手术治疗至关重要。长链非编码rna (lncRNAs)可作为肿瘤的生物标志物和治疗靶点。我们研究了lncRNA kcnq10t1在黑色素瘤中的分子机制。Real - time PCR结果显示,kcnq10t1在黑色素瘤组织和细胞中表达上调。kcnq10t1促进黑色素瘤细胞增殖和转移。通过直接结合miR-153, kcnq10t1作为竞争内源性RNA (ceRNA)去抑制MET表达。我们的结果可能为早期发现和/或治疗黑色素瘤的新策略提供基础。
Melanoma is the deadliest cutaneous neoplasm. To prevent metastasis, early diagnosis and surgical treatment is vital. Long non-coding RNAs (lncRNAs) may serve as biomarkers and therapeutic targets in tumors. We investigated the molecular mechanisms of lncRNA KCNQ1OT1 in melanoma. Real time PCR demonstrated that KCNQ1OT1 expression is up-regulated in melanoma tissues and cells. KCNQ1OT1 promoted cell proliferation and metastasis in melanoma. By directly bindin to miR-153, KCNQ1OT1 acted as a competing endogenous RNA (ceRNA) to de-repress MET expression. Our results may provide the basis for a novel strategy for early detection and/or treatment of melanoma.
