We demonstrated that the productive infection of three different mammalian cell lines with two separate leukemia viruses is sufficient to induce a change in surface architecture that may be detected as enhanced agglutinability with two different plant lectins. Subsequent transformation of one of these cell lines with a chemical carcinogen did not further modify the agglutinability of the cell lines. Using a polyoma virus-transformed derivative of one of the parental lines, we have demonstrated that the LETS protein (whose absence from the surface membrane has been considered a marker of the transformed phenotype) may be present in cells displaying the capacity to plate in soft agar.
我们证明,两种不同的白血病病毒对三种不同的哺乳动物细胞系进行有效感染,足以诱导细胞表面结构发生变化,这种变化可表现为对两种不同植物凝集素的凝集性增强。随后用化学致癌物对其中一个细胞系进行转化,并未进一步改变这些细胞系的凝集性。利用亲本细胞系之一的多瘤病毒转化衍生物,我们证明,LETS蛋白(其在细胞膜表面的缺失被认为是转化表型的一个标志)可能存在于具有在软琼脂中铺板能力的细胞中。
