    • The present invention describes novel methods of constructing recombinant adenoviral vectors capable of expressing human cDNAs, such as wild-type p53, WAF1/Cip1/p21, p27/kip1, E. coli cytosine deaminase, wild-type p16, TAM 67 (a jun/fos dominant negative mutant) and B7-1 and B7-2. The invention further provides methods of inhibiting the proliferation of cells, inhibiting the cell cycle of proliferating cells, and methods for the eradication of cells, especially cancer and diseased cells, by infecting the cells with a recombinant adenovirus vector capable of expressing human cDNAs. Compositions and methods of the invention are suitable for treatment of a subject afflicted with a tumor wherein the cells of the tumor, for example, lack the wild-type p53 allele and/or possess a mutated p53 gene. The invention additionally provides a method for the use of adenoviral vectors in the treatment of cancer cells, such as lung cancer and breast cancer cells. The invention further provides methods for the use of adenoviral vectors in cancer gene therapy as a mechanism for purging bone marrow cells of contaminanting tumor cells, for eradicating cancer cells, and for preventing development of cancer cells and tumors.
    • 本发明描述了构建能够表达人cDNA的重组腺病毒载体的新方法,例如野生型p53,WAF1 / Cip1 / p21,p27 / kip1,大肠杆菌胞嘧啶脱氨酶,野生型p16,TAM 67 / fos显性阴性突变体)和B7-1和B7-2。 本发明还提供了通过用能够表达人cDNA的重组腺病毒载体感染细胞来抑制细胞增殖,抑制增殖细胞的细胞周期的方法,以及根除细胞,特别是癌症和患病细胞的方法。 本发明的组合物和方法适用于治疗患有肿瘤的受试者,其中肿瘤的细胞例如缺少野生型p53等位基因和/或具有突变的p53基因。 本发明另外提供了一种使用腺病毒载体来治疗癌细胞如肺癌和乳腺癌细胞的方法。 本发明进一步提供了在癌基因治疗中使用腺病毒载体作为清除污染性肿瘤细胞的骨髓细胞,用于根除癌细胞和预防癌细胞和肿瘤的发展的机制的方法。
