Replication-selective oncolytic virotherapy provides a novel modality to treat cancer by inducing cell death in tumor cells but not in normal cells. However, the utilization of oncolytic viruses as a stand-alone treatment is problematic due to their poor transduction efficiency . H101 was the first oncolytic adenovirus (Ads) to be approved by the Chinese FDA, and exhibits modest antitumor effects when applied as a single agent. The multiple histone deacetylase inhibitor trichostatin A (TSA) has been demonstrated to potently enhance the spread and replication of oncolytic Ads in several infection-resistant types of cancer. The present study aimed to investigate the antitumor effects of H101 in combination with TSA on esophageal squamous cell carcinoma (ESCC) and , and determine the mechanisms underlying these effects. H101 and TSA in combination increased the survival of mice harboring human ESCC cell line-tumor xenografts, as compared with mice treated with these agents individually. Therefore, TSA may enhance the antitumor effects of H101 in ESCC.
复制选择性溶瘤病毒疗法提供了一种通过诱导肿瘤细胞而非正常细胞死亡来治疗癌症的新方法。然而,由于溶瘤病毒的转导效率低,将其作为单一疗法使用存在问题。H101是首个被中国食品药品监督管理总局批准的溶瘤腺病毒,作为单一药物应用时表现出适度的抗肿瘤效果。多种组蛋白脱乙酰酶抑制剂曲古抑菌素A(TSA)已被证明能有效增强溶瘤腺病毒在几种抗感染类型癌症中的传播和复制。本研究旨在探讨H101与TSA联合应用对食管鳞状细胞癌(ESCC)的抗肿瘤作用,并确定其作用机制。与单独使用这些药物治疗的小鼠相比,H101和TSA联合应用提高了携带人ESCC细胞系肿瘤异种移植瘤小鼠的生存率。因此,TSA可能增强H101对ESCC的抗肿瘤作用。
