microRNA-501-5p通过靶向CYLD促进子宫颈癌细胞增殖、迁移和侵袭能力
发布时间：2024-04-11 00:24
研究背景:在世界范围内子宫颈癌是一种常见的女性致死性恶性肿瘤,尽管子宫颈癌近年来的发病率和死亡率明显下降,它依旧在女性常见肿瘤中位居第四位。microRNAs(miRNAs)是一类单链非编码小RNA分子,其长度为18-24个碱基,可与靶m RNA通过碱基互补配对相结合,导致靶m RNA降解或者抑制其翻译。在过去的十几年中,在包括子宫颈癌在内的肿瘤领域,越来越多的研究表明miRNA扮演着一个重要调控者的角色。microRNA-501-5p(miR-501)是一种非保守的miRNA,作为肿瘤发生的潜在关键因子而出现。目前的证据表明miR-501在一些恶性肿瘤中过表达,包括肝癌,胃癌和通过促进细胞增殖作为癌细胞起作用的肺癌。此外,miR-501高表达可能是胃癌患者总体生存预测不良的指标。然而,miR-501对宫颈癌的影响和潜在机制尚未探索。CYLD基因位于染色体16q12.1上,编码去泛素化酶。CYLD基因突变与家族性圆筒瘤(FC),多发性家族性毛发上皮瘤(MFT)和多发性骨髓瘤相关。在肾癌,HCC和子宫颈玻璃状细胞癌细胞系中报道了CYLD的拷贝数减少。同时,在结直肠癌,乳腺癌和肺癌中发现抑...
