Long non-coding RNAs (lncRNAs) have been reported to play a crucial role in the pathogenesis of numerous cancers. However, the function of lncRNA KCNMB2-AS1 in bladder cancer (BC) remains unclear. In the present study, we aimed to explore the role and underlying mechanisms of KCNMB2-AS1 in bladder cancer progression. We found that lncRNA KCNMB2-AS1 was significantly upregulated both in BC tissues and cell lines, the expression level was highly correlated with pathological TNM stage. Functionally, knockdown of lncRNA KCNMB2-AS1 dramatically inhibited the proliferation, migration, and invasion and of BC cells , and suppressed tumor growth . Mechanistically, lncRNA KCNMB2-AS1 could function as a competitive endogenous RNA (ceRNA) through direct sponging miR-374a-3p, which regulated the expression of S100A10. In conclusion, our results demonstrated that lncRNA KCNMB2-AS1 can promote the progression of bladder cancer through regulation of miR-374a-3p/S100A10.
据报道，长链非编码RNA（lncRNAs）在多种癌症的发病机制中起关键作用。然而，lncRNA KCNMB2-AS1在膀胱癌（BC）中的功能仍不清楚。在本研究中，我们旨在探讨KCNMB2-AS1在膀胱癌进展中的作用及潜在机制。我们发现lncRNA KCNMB2-AS1在BC组织和细胞系中均显著上调，其表达水平与病理TNM分期高度相关。在功能上，敲低lncRNA KCNMB2-AS1可显著抑制BC细胞的增殖、迁移和侵袭，并抑制肿瘤生长。机制上，lncRNA KCNMB2-AS1可通过直接结合miR-374a-3p作为竞争性内源性RNA（ceRNA）发挥作用，从而调控S100A10的表达。总之，我们的结果表明lncRNA KCNMB2-AS1可通过调控miR-374a-3p/S100A10促进膀胱癌进展。
