Abstract:

葡萄膜黑色素瘤是成人最严重的原发性恶性肿瘤之一.传统的治疗方法,包括手术、放射治疗和化学治疗效果都不是很理想.溶瘤腺病毒H101,能够特异性地在p53突变的肿瘤细胞中复制并杀伤肿瘤细胞,同时对正常细胞影响较少,且已由中国国家食品药品监督管理总局批准上市.为了研究H101对葡萄膜黑色素瘤的治疗效果,通过体外感染葡萄膜黑色素瘤细胞,发现H101能够显著抑制葡萄膜黑色素瘤细胞的增殖并促进细胞凋亡,抑制细胞周期,而对正常的ARPE-19细胞没有影响.在体内实验中,建立了SP6.5细胞的荷瘤小鼠模型,在H101治疗后抑制了肿瘤的生长,延长了动物寿命.上述结果表明,溶瘤腺病毒H101治疗葡萄膜黑色素瘤是一种可行的方法.
