    • The invention relates to novel human DNA sequences, targeting constructs, and methods for producing novel genes encoding thrombopoietin, DNase I, and &bgr;-interferon by homologous recombination. The targeting constructs comprise at least: a) a targeting sequence; b) a regulatory sequence; c) an exon; and d) a splice-donor site. The targeting constructs, which can undergo homologous recombination with endogenous cellular sequences to generate a novel gene, are introduced into cells to produce homologously recombinant cells. The homologously recombinant cells are then maintained under conditions which will permit transcription of the novel gene and translation of the mRNA produced, resulting in production of either thrombopoietin, DNase I, or &bgr;-interferon. The invention further relates to a methods of producing pharmaceutically useful preparations containing thrombopoietin, DNase I, or &bgr;-interferon from homologously recombinant cells and methods of gene therapy comprising administering homologously recombinant cells producing thrombopoietin, DNase I, or &bgr;-interferon to a patient for therapeutic purposes.
    • 本发明涉及新的人DNA序列,靶向构建体,以及通过同源重组产生编码血小板生成素,DNA酶I和β-干扰素的新基因的方法。 靶向构建体至少包括:a)靶向序列; b)调节序列; c)外显子 和d)剪接供体位点。 将可与内源细胞序列进行同源重组以产生新基因的靶向构建体导入细胞以产生同源重组细胞。 然后将同源重组细胞保持在允许新基因转录和产生的mRNA翻译的条件下,导致产生血小板生成素,DNA酶I或β-干扰素。 本发明进一步涉及一种生产含有血浆生成素,DNA酶I或β-干扰素的同种重组细胞的药用制剂的方法和基因治疗方法,包括向患者施用产生血小板生成素,DNA酶I或β-干扰素的同源重组细胞, 治疗目的。
