Wilms' tumor is a malignant renal cancer that arises within the pediatric urinary system. This study intended to investigate how a novel long non-coding RNA LINC01339 functions in the pathogenesis of Wilms' tumor. An elevated miR-135b-3p expression as well as reduced levels of LINC01339 and ADH1C were observed in Wilms' tumor. LINC01339 mediated ADH1C expression by directly binding to miR-135b-3p. The enforced LINC01339 or ADH1C markedly hindered cell growth and migration in Wilms' tumor. The LINC01339 overexpression also repressed the growth of Wilms' tumors in vivo, whereas miR-135b-3p overexpression exerted the opposite effects on Wilms' tumor cells in vitro. Additionally, upregulating miR-135b-3p reversed LINC01339's effects on the cellular processes of Wilms' tumor cells, whereas ADH1C overexpression offset the cancer-promoting influence of miR-135b-3p upregulation on Wilms' tumor progression. Therefore, LINC01339 prevents Wilms' tumor progression by modulating the miR-135b-3p/ADH1C axis. Our findings substantiate that the LINC01339/miR-135 b-3p/ADH1C regulatory axis has potential to be a target for the treatment of Wilms' tumor.
威尔姆斯瘤是一种起源于小儿泌尿系统的恶性肾肿瘤。本研究旨在探讨新型长链非编码 RNA LINC01339 在威尔姆斯瘤发病机制中的作用。研究发现,威尔姆斯瘤中 miR-135b-3p 表达升高,LINC01339 和 ADH1C 水平降低。LINC01339 通过直接结合 miR-135b-3p 介导 ADH1C 的表达。强制表达 LINC01339 或 ADH1C 可显著抑制威尔姆斯瘤细胞的生长和迁移。LINC01339 的过表达也抑制了体内威尔姆斯瘤的生长,而 miR-135b-3p 的过表达则对体外威尔姆斯瘤细胞产生相反的影响。此外,上调 miR-135b-3p 可逆转 LINC01339 对威尔姆斯瘤细胞细胞过程的影响,而 ADH1C 的过表达则抵消了 miR-135b-3p 上调对威尔姆斯瘤进展的促进作用。因此,LINC01339 通过调节 miR-135b-3p/ADH1C 轴防止威尔姆斯瘤的进展。我们的研究结果证实,LINC01339/miR-135b-3p/ADH1C 调控轴有可能成为治疗威尔姆斯瘤的靶点。
