The functions of Long noncoding RNA (lncRNA) HOXB-AS1 have been investigated in glioblastoma and multiple myeloma. However, the role of lncRNA HOXB-AS1 in endometrial carcinoma (EC) remains largely unknown. This study investigated the underlying mechanisms of the lncRNA HOXB-AS1 on the progression of EC. In this study, We found that HOXB-AS1 expression was significantly upregulated in EC tissue samples and was associated with shorter survival time. Furthermore, upregulation of HOXB-AS1 promoted proliferation, invasion, and migration of EC cell. HOXB-AS1 and Wnt10b directly bound to miR-149-3p. HOXB-AS1 increased the expression of Wnt10b by binding to miR-149-3p. We further verified the upregulation of β-catenin, cyclin D1, and c-myc induced by HOXB-AS1. In conclusion, our results indicated that HOXB-AS1 exerted oncogenic function as competing endogenous RNA (ceRNA) of miR-149-3p to release Wnt10b and activated Wnt/β-catenin pathway.

长链非编码 RNA（lncRNA）HOXB-AS1 的功能已在神经胶质瘤和多发性骨髓瘤中进行了研究。然而，lncRNA HOXB-AS1 在子宫内膜癌（EC）中的作用在很大程度上尚不清楚。本研究探讨了 lncRNA HOXB-AS1 对 EC 进展的潜在机制。在这项研究中，我们发现 HOXB-AS1 在 EC 组织样本中的表达显著上调，并且与较短的生存时间有关。此外，HOXB-AS1 的上调促进了 EC 细胞的增殖、侵袭和迁移。HOXB-AS1 和 Wnt10b 直接与 miR-149-3p 结合。HOXB-AS1 通过与 miR-149-3p 结合增加了 Wnt10b 的表达。我们进一步验证了 HOXB-AS1 诱导的β-catenin、cyclin D1 和 c-myc 的上调。总之，我们的结果表明，HOXB-AS1 作为 miR-149-3p 的竞争性内源 RNA（ceRNA）发挥致癌功能，释放 Wnt10b 并激活 Wnt/β-catenin 通路。
