A tissue culture line derived from the Asian rodent Vandeleuria oleracea has been shown to release an infectious, xenotropic type C virus. The virus-associated reverse transcriptase (RNA-dependent DNA nucleotidyltransferase) and the major internal protein p30 are immunologically related to the respective proteins of the woolly monkey-gibbon ape group of infectious primate viruses. By these criteria the V. oleracea viral isolate is similar to the murine type C-I class of endogenous retroviruses and has been designated Vand C-I. Nucleic acid homology studies show that V. oleracea cellular DNA shares similar levels of homology with DNA from members of the Mus and Rattus genera and lower levels of homology with other rodent genera. The Vand C-I viral genome is present in V. oleracea cellular DNA in multiple copies, and partially related sequences can be detected in other rodent genera. These results support the conclusion that the Vand C-I viral genome is genetically transmitted in V. oleracea and that the type C-I class of endogenous retroviral genes has been highly conserved during evolution.
源自亚洲啮齿动物印度攀鼠的一个组织培养系已被证明能释放一种具有感染性的嗜异性C型病毒。病毒相关的逆转录酶(RNA依赖性DNA核苷酸转移酶)和主要内部蛋白p30在免疫上与传染性灵长类病毒的绒毛猴-长臂猿类群的相应蛋白相关。根据这些标准,印度攀鼠病毒分离株类似于内源性逆转录病毒的鼠C-I类,并被命名为Vand C-I。核酸同源性研究表明,印度攀鼠细胞DNA与小家鼠属和大鼠属成员的DNA具有相似水平的同源性,而与其他啮齿动物属的同源性较低。Vand C-I病毒基因组以多拷贝形式存在于印度攀鼠细胞DNA中,并且在其他啮齿动物属中可以检测到部分相关序列。这些结果支持了Vand C-I病毒基因组在印度攀鼠中通过遗传传递以及内源性逆转录病毒基因的C-I类在进化过程中高度保守的结论。
