宫颈癌是全球女性癌症相关的第二大常见死亡原因,全世界每年约有50万新发病例,约23万妇女死于宫颈癌,仅次于乳腺癌。宫颈癌发病率高,且近年来有发病年轻化的趋势,严重危害妇女身心健康。对于宫颈癌的早期诊断和治疗是降低肿瘤死亡率的有效途径。microRNA(miRNA)是近年来新发现的一类长约21~23个核甘酸的小分子非编码调控的单链RNA~[1],miRNA自从被发现以来,即成为生命科学 Cervical cancer is the second most common cause of cancer in women worldwide. About 500,000 new cases occur each year in the world and about 230,000 women die of cervical cancer, second only to breast cancer. High incidence of cervical cancer, and in recent years the incidence of younger trend, seriously endanger women’s physical and mental health. For the early diagnosis and treatment of cervical cancer is an effective way to reduce tumor mortality. MicroRNA (miRNA) is a newly discovered small-molecule non-coding single-stranded RNA with a length of about 21-23 nucleotides recently [1]. Since its discovery, miRNA has become a life science
