MH2 和 MC29 的基因组已被证明高度相似,并且包含相同的致癌序列(称为 myc)。这两种病毒均可在体外转化日本鹌鹑(Coturnix coturnix japonica)胚胎成纤维细胞和成熟的外周血巨噬细胞。然而,3周龄鹌鹑体内感染后观察到显着差异。这两种病毒都不会引起肉瘤或骨髓细胞瘤。 MC29仅有弱致癌性; 29 只鸟中只有两只出现了位于肝脏的肿瘤。相比之下,MH2 具有高度致癌性;鸟类通常在注射部位附近出现实体瘤或肝肿瘤。当实体瘤置于培养物中时,它们产生了转化的巨噬细胞,令人惊讶的是,产生了未转化的红细胞样细胞。 MH2和MC29在体外也表现出不同的巨噬细胞和成纤维细胞转化效率。据推测,两种病毒之间的生物学差异可能与myc序列加工的差异有关。
The genomes of MH2 and MC29 have been shown to be highly similar and contain the same oncogenic sequence termedmyc. Both viruses can transform Japanese quail (Coturnix coturnix japonica) embryo fibroblasts and mature peripheral blood macrophagesin vitro. However, a striking difference is observed afterin vivoinfection of 3-week-old quail. Neither virus causes either sarcomas or myelocytomas. MC29 is only weakly oncogenic; only two of 29 birds developed tumors which were localized in the liver. In contrast MH2 is highly oncogenic; birds generally developed solid tumors near the site of injection, or liver tumors. When the solid tumors were placed in culture they gave rise to transformed macrophages, and surprisingly, erythrocyte-like cells, which were not transformed. MH2 and MC29 also exhibited different efficiences of macrophage and fibroblast transformationin vitro. It is postulated that the biological differences between the two viruses could be related to differences in processing ofmycsequences.
