Recent research has underscored the critical role of long non-coding RNAs (lncRNAs) in tumorigenesis and malignancy development. Nevertheless, the role of lncRNA cytoskeleton regulator RNA (CYTOR) in the progression of melanoma remains only partially elucidated. This research seeks to explore the impact of CYTOR on melanoma development and to elucidate the molecular mechanisms involved.
and models were used to assess CYTOR expression levels by QPCR and Western blotting. Melanoma cell proliferation, migration, and invasion were assessed by CCK-8 assay, scratch wound assay and transwell invasion experiments. The mechanism of CYTOR promoting melanoma progression was verified in a xenograft tumor mouse model.
Our investigation identified a marked increase in CYTOR expression levels in both melanoma tissues and cells. Experiments conducted both and revealed that CYTOR markedly stimulated melanoma cell proliferation, migration, and invasion. Dual-luciferase reporter assays confirmed the direct binding of miR-485-5p to CYTOR, and glucose-6-phosphate isomerase (GPI) was identified as a direct target of miR-485-5p.
近期研究强调了长链非编码RNA(lncRNAs)在肿瘤发生和恶性发展中的关键作用。然而,lncRNA细胞骨架调节RNA(CYTOR)在黑色素瘤进展中的作用仍未完全阐明。本研究旨在探讨CYTOR对黑色素瘤发展的影响,并阐明其中涉及的分子机制。
采用QPCR和蛋白质免疫印迹法评估CYTOR在细胞系和动物模型中的表达水平。通过CCK-8法、划痕实验和Transwell侵袭实验评估黑色素瘤细胞的增殖、迁移和侵袭能力。在异种移植瘤小鼠模型中验证CYTOR促进黑色素瘤进展的机制。
我们的研究发现CYTOR在黑色素瘤组织和细胞中的表达水平显著升高。体内和体外实验均表明CYTOR显著促进黑色素瘤细胞的增殖、迁移和侵袭。双荧光素酶报告基因检测证实miR-485-5p与CYTOR直接结合,且葡萄糖-6-磷酸异构酶(GPI)被确定为miR-485-5p的直接靶点。
