晚期头颈部鳞状细胞癌(HNSCC)尽管采用积极的多模式治疗,但预后不良。本研究的目的是测试基因转导作为头颈部癌新疗法的可行性。用含有lacZ标记基因的复制缺陷型重组腺病毒(Ad 2/CMV β gal)体外转导三种人HNSCC细胞系。基因转导效率取决于感染的多重性、暴露于病毒的持续时间和病毒浓度。接着,用含有单纯疱疹病毒胸苷激酶(HSVtk)基因的腺病毒载体(Ad.RSVtk)转导HEp-2细胞系,当表达时,所述基因使转导的细胞对更昔洛韦(GCV)敏感。随后给予GCV导致完全的肿瘤细胞杀伤。这些结果表明,腺病毒介导的KSVtk转移和GCV给药可能成为HNSCC的新治疗方法。
Advanced head and neck squamous cell carcinomas (HNSCCs) have a poor prognosis despite aggressive multimodal therapy. The goal of our study was to test the feasibility of gene transduction as a novel therapy for head and neck cancer. Three human HNSCC cell lines were transduced in vitro with a replication-deficient recombinant adenovirus containing the lacZ marker gene (Ad2/CMVßgal). Gene transduction efficiency was dependent on multiplicity of infection, duration of exposure to the virus, and viral concentration. Next, the HEp-2 cell line was transduced with an adenoviral vector (Ad.RSVtk) containing the herpes simplex virus thymidine kinase (HSVtk) gene, which, when expressed, sensitizes transduced cells to ganciclovir (GCV). Subsequent administration of GCV resulted in complete rumor cell killing. These results suggest that adenovirus-mediated transfer of KSVtkand administration of GCV has potential as a new therapy for HNSCC.
