    中国病毒学000301摘要:用不同浓度的EB病毒4种(BHRF1、DNA酶、核抗原-1及胸苷激酶)反义寡核苷酸片段,(antisense oligodeoxynucleotide, ASO)分别与含10%胎牛血清或不含胎牛血清的人低分化鼻咽癌细胞株(SUNE-1)共同培养48 h。结果仅适当浓度的BHRF1-ASO能引起无血清培养的SUNE-1细胞株增殖明显受抑制,透射电镜及琼脂糖凝胶电泳检测结果发现与SUNE-1细胞发生凋亡有关;而相同浓度的DNA酶、核抗原1和胸苷激酶基因的ASO则无类似作用。

    Abstract: Poorly differentiated nasopharyngeal carcinoma (SUNE-1) cell line was cultured with Epstein-Barr virus (EBV) BHRF1, DNase, thymidine kinase (TK) and nuclear antigen-1 (EBNA1) antisense oligodeoxynucleotide (ASO) for 48 h respectively. Inhibited proliferation of SUNE-1 was only observed in the absence of fetal calf serum (FCS) and exposed to EBV-BHRF1-ASO. The results from electron microscopy and agarose gel electrophoresis indicated that apoptosis only appeared in SUNE-1 cells exposed to BHRF1-ASO and absence of FCS. The other 3 kinds of EBV-ASOs had not the similar effects at the same concentration.
