Renal cell carcinoma (RCC) is the most common type of kidney cancer and the prognosis of metastatic RCC remains poor, with a high rate of recurrence and mortality. Long non‑coding RNA (lncRNA) is a class of RNA which serves important roles in multiple cellular processes and tumorigenesis. In the present study, the expression and function of lncRNA eosinophil granule ontogeny transcript (EGOT) were examined in RCC. In 24 paired tissues (RCC tissues and adjacent normal tissues) the results of reverse transcription‑quantitative polymerase chain reaction analysis revealed that EGOT was downregulated in 22 RCC tissues compared with paired tissues. Upregulation of lncRNA EGOT by transfection of 786‑O and ACHN RCC cells with pcDNA3.1‑EGOT suppressed cell proliferation, migration and invasion, and induced RCC cell apoptosis. The results demonstrated that EGOT may serve as a tumor suppressor in RCC and may be a potential prognostic biomarker of RCC.
肾细胞癌(RCC)是最常见的肾癌类型,转移性 RCC 的预后仍然较差,复发率和死亡率均较高。长链非编码 RNA(lncRNA)是一类在多种细胞过程和肿瘤发生中发挥重要作用的 RNA。在本研究中,研究了 lncRNA 嗜酸性粒细胞颗粒发生转录物(EGOT)在 RCC 中的表达和功能。在 24 对组织(RCC 组织和相邻正常组织)中,逆转录定量聚合酶链反应分析的结果显示,与配对组织相比,22 例 RCC 组织中 EGOT 下调。通过 pcDNA3.1-EGOT 转染 786-O 和 ACHN RCC 细胞上调 lncRNA EGOT,抑制了细胞增殖、迁移和侵袭,并诱导 RCC 细胞凋亡。结果表明,EGOT 可能在 RCC 中作为一种肿瘤抑制因子发挥作用,并且可能是 RCC 的潜在预后生物标志物。
