Abstract
Objective
To evaluate the inhibitory role of a novel oncolytic adenovirus (OA), GP73-SphK1sR-Ad5, on the growth of hepatocellular carcinoma (HCC).
Methods
GP73-SphK1sR-Ad5 was constructed by integrating Golgi protein 73 (GP73) promoter and sphingosine kinase 1 (SphK1)-short hairpin RNA (shRNA) into adenovirus serotype 5 (Ad5), and transfecting into HCC Huh7 cells and normal human liver HL-7702 cells. The expression of SphK1 and adenovirus early region 1 (E1A) was detected by quantitative real-time PCR (qRT-PCR) and western blot, respectively. Cell viability was detected by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay, and apoptotic rate was determined by flow cytometry. An Huh7 xenograft model was established in mice injected intratumorally with GP73-SphK1sR-Ad5. Twenty days after injection, the tumor volume and weight, and the survival time of the mice were recorded. The histopathological changes in tumor tissues were observed by hematoxylin-eosin (HE) staining and transmission electron microscopy (TEM).
Results
Transfection of GP73-SphK1sR-Ad5 significantly upregulated E1A and downregulated SphK1 in Huh7 cells, but not in HL7702 cells. GP73-SphK1sR-Ad5 transfection significantly decreased the viability and increased the apoptotic rate of Huh7 cells, but had no effect on HL7702 cells. Intratumoral injection of GP73-SphK1sR-Ad5 into the Huh7 xenograft mouse model significantly decreased tumor volume and weight, and prolonged survival time. It also significantly decreased the tumor infiltration area and blood vessel density, and increased the percentages of cells with nucleus deformation and cells with condensed chromatin in tumor tissues.
Conclusions
GP73-SphK1sR-Ad5 serves as a novel OA and can inhibit HCC progression with high specificity and efficacy.
概要
目 的

创新点
GP73-SphK1sR-Ad5 是一种新型的溶瘤腺病毒, 可以特异及有效地抑制肝癌细胞生长, 为肝癌的 临床治疗提供新思路。
方 法
通过整合高尔基体蛋白 73 (GP73) 及鞘氨基醇 及鞘氨基醇 激酶 1 (SphK1) 构建了 GP73-SphK1sR-Ad5 腺 病毒, 进而转染肝癌 Huh7 细胞及正常 HL7702 肝细胞。通过实时定量 PCR 和蛋白印记实验检测 SphK1 和 E1A 基因的表达; 通过四氮唑盐比色分 析法 (MTT 法) 检测细胞活力; 通过流式细胞术 检测细胞凋亡率。构建 Huh7 异种移植小鼠模型 并注射 GP73-SphK1sR-Ad5 腺病毒。 20 天后, 记 录小鼠肿瘤体积和重量, 以及存活时间。用苏木 精-伊红 (HE) 染色法和透射电镜 (TEM) 观察 肿瘤组织的病理变化。
结 果
GP73-SphK1sR-Ad5 转染显著上调了 Huh7 细胞中 E1A 的表达, 下调了 SphK1 的表达, 降低了细胞 活性, 并提高了凋亡率, 然而对 HL7702 细胞无 明显影响。 Huh7 异种移植小鼠模型内注射 GP73-SphK1sR-Ad5 显著降低了肿瘤的体积和重 量, 延长了小鼠的存活时间 并降低了肿瘤组织 中的肿瘤浸润面积、血管密度及核变形和染色质 浓缩的细胞数。
