    • A novel method and composition are provided for the replication and expression of exogenous genes in eukaryotic cells. A segment of a papilloma virus genome capable of extrachromosomal replication is linked to the foreign gene(s) using recombinant DNA techniques to provide a biologically functional replicon with a desired phenotypical property. The replicon is inserted into a eukaryotic cell by transformation, and the isolation of transformant provides cells for replication and expression of the DNA molecules present in the modified plasmid. The transforming region of the bovine papilloma virus provides a unique vector in that it provides both the capability of autonomous extrachromosomal replication but also the malignant transformed phenotype. Thus, genes which of themselves provide no selectable phenotypical property can be conveniently and efficiently introduced into eukaryotic cells and the transformants selected. The method is useful in that the foreign DNA is faithfully expressed and the gene products (proteins), such as pro-insulin (an insulin precursor) is synthesized.
    • 提供了一种新颖的方法和组合物,用于在真核细胞中复制和表达外源基因。 使用重组DNA技术将能够染色体外复制的乳头瘤病毒基因片段与外源基因连接,以提供具有所需表型性质的生物功能复制子。 通过转化将复制子插入真核细胞,转化体的分离提供用于复制和表达修饰质粒中存在的DNA分子的细胞。 牛乳头瘤病毒的转化区域提供了独特的载体,因为它提供了自主染色体外复制的能力,而且提供了恶性转化的表型。 因此,本身不提供选择性表型性质的基因可以方便且有效地引入真核细胞并选择转化体。 该方法可用于外来DNA被忠实表达,并且合成基因产物(蛋白质),例如胰岛素前体(胰岛素前体)。

    • A gene which is associated with tumor suppression and is localized on chromosome 11 has now been identified. The identification, localization and sequence of a gene which demonstrates differential expression in a manner that correlates with tumorigenicity suggests that this gene could potentially be used for gene therapy in cancers deleted or altered in their expression of the gene. Furthermore, a gene which is localized on chromosome 11p15, with identified polymorphisms, could be used for analysis of tumor DNA for loss of heterozygosity at chromosome 11p15. This region of chromosome 11 shows frequent loss of heterozygosity (LOH) in many human malignancies. Thus, the determination of LOH at chromosome 11p15 may be useful in predicting the prognosis of that tumor.
    • 与肿瘤抑制相关并位于第11号染色体上的基因已被鉴定。 以与致瘤性相关的方式表达差异表达的基因的鉴定,定位和序列表明该基因可潜在地用于在其基因表达中被删除或改变的癌症中的基因治疗。 此外,位于染色体11p15上的基因,具有确定的多态性,可用于分析染色体11p15上杂合性丧失的肿瘤DNA。 染色体11的这个区域在许多人类恶性肿瘤中表现出频繁的杂合性损失(LOH)。 因此,染色体11p15上的LOH的测定可用于预测该肿瘤的预后。
