Dyrk1B调控HPV E7表达细胞在静止状态下越过G0/1/S检测点进入S期的机制研究
发布时间:2021-08-15 11:32
人乳头瘤病毒(Human papillomaviruses, HPV)按病毒致癌能力的大小分为低危型HPV (HPV 6,11等)和高危型HPV (HPV 16,18等),低危型HPV主要引起良性外生性疣,宫颈上皮内瘤变(cervical intraepithelial neoplasm, CIN),高危型HPV主要引起宫颈上皮内中、高度瘤变(CINⅡ、CIN Ⅲ)和宫颈浸润性鳞癌。女性最常见的恶性肿瘤之一是宫颈癌,在全球女性恶性肿瘤中仅次于乳腺癌居第二位。90%的宫颈癌患者可检测到高危型HPV DNA,宫颈癌的必备条件是持续高危HPV感染引起CIN病变持续和进展,从而导致癌症的发生。宫颈癌标本中,HPV 16、18型感染占70%以上,其中16型HPV占51.0%。HPV是小环状DNA病毒,其转化功能主要依赖于早期蛋白E7以及E6,其中E7降解抑癌蛋白pRb,释放与Rb结合的转录因子E2F,启动DNA复制所需蛋白的转录,引起细胞增殖紊乱与基因组不稳定性。在转基因鼠模型中,高度宫颈上皮内瘤变(high-grade cervical intraepithelial neoplasia, C...
