As the most common and aggressive malignant form of skin cancer, melanoma has a poor prognosis in its late stage. MicroRNA (miR)-520d-3p has been reported as a key modulator that regulates the development of different types of cancer, but its role in melanoma remains unclear. The purpose of this study was to investigate the role and mechanism of miR-520d-3p in melanoma. The expression of anti-silencing function 1B histone chaperone () and miR-520d-3p in melanoma tissues and cells was detected by reverse transcription-quantitative polymerase chain reaction. The interaction between and miR-520d-3p was verified by luciferase activity detection. Cell counting kit-8, bromodeoxyuridine, fluorescein isothiocyanate, and cell adhesion assays were performed to detect cell viability, proliferation, apoptosis, and adhesion in melanoma cells. expression was evidently increased, whereas miR-520d-3p level was downregulated in melanoma tissues and cells. Overexpression of enhanced cell growth and adhesion and hampered cell apoptosis in melanoma cells. Furthermore, miR-520d-3p suppressed the tumorigenic effects of melanoma cells. Moreover, miR-520d-3p suppressed the expression of to suppress melanoma tumorigenesis. In conclusion, we have found out that miR-520d-3p suppressed melanoma tumorigenesis by inhibiting , which could be a promising target for melanoma therapy.
作为最常见和侵袭性最强的皮肤癌恶性形式,黑色素瘤在晚期预后较差。microRNA(miR)-520d-3p 已被报道为调节不同类型癌症发展的关键调节剂,但它在黑色素瘤中的作用尚不清楚。本研究旨在探讨 miR-520d-3p 在黑色素瘤中的作用和机制。通过逆转录定量聚合酶链反应检测黑色素瘤组织和细胞中抗沉默功能 1B 组蛋白伴侣()和 miR-520d-3p 的表达。通过荧光素酶活性检测验证和 miR-520d-3p 之间的相互作用。细胞计数试剂盒-8、溴脱氧尿苷、异硫氰酸荧光素和细胞黏附试验检测黑色素瘤细胞的细胞活力、增殖、凋亡和黏附。结果表明,在黑色素瘤组织和细胞中,表达明显增加,而 miR-520d-3p 水平下调。 过表达增强了黑色素瘤细胞的生长和黏附能力,同时抑制了细胞凋亡。此外,miR-520d-3p 抑制了黑色素瘤细胞的致瘤作用。进一步研究发现,miR-520d-3p 通过抑制抑制黑色素瘤的发生。综上所述,我们发现 miR-520d-3p 通过抑制抑制黑色素瘤的发生,从而抑制黑色素瘤的肿瘤发生,这可能是黑色素瘤治疗的一个有前途的靶点。
