    • Agents for stimulating the dividing activity of mammalian cells are presented, which have as an active substance a nucleotide sequence with a complimentary sequence (anti-sense) to a domain of the mRNA of tumor suppressor retinoblastoma or p16 genes acting on cell dividing activity. For Rb, the agents are nucleotide sequences 5'-GGTTTTGGGCGGCATGAC-3' (SEQ ID NO: 1) and 5'-CTCAGTAAAAGTGAACGA-3' (SEQ ID NO: 2); a nucleotide sequence comprising 49 base pairs, wherein the domain of the mRNA comprises nucleotides 124 to 152; and a 360 base pair nucleotide wherein the domain of the mRNA comprises an Hpa I restriction endonuclease site, an ASP718 endonuclease site, a portion of the 5' untranslated domain of the Rb gene, and a first exon of the Rb gene. For p16, the agent comprises GATCCATGCT GCTCC (SEQ ID NO: 3).

    • A method of inhibiting hepatitis C virus RNA replication or expression is provided. The method consists of introducing two or more ribozymes specific for hepatitis C virus RNA into a cell infected with hepatitis C virus. The ribozymes specific for hepatitis C virus RNA can specifically cleave hepatitis C RNA in a HCV 5' non-coding sequence, the capsid sequence, the NS-5 sequence or any other conserved region of the hepatitis C RNA. The ribozymes can also be selected so as to be specific for opposite strands of the virus genome. A method of inhibiting hepatitis C virus RNA replication or expression is also provided which consists of introducing into a cell infected with hepatitis C virus at least one ribozyme specific for hepatitis C virus which is selected from the group consisting of GGGAGGTCTCGTAGA [SEQ ID NO: 1], GCACCATGAGCACGA [SEQ ID NO: 2], CCCACAGGACGTCAA [SEQ ID NO: 3], CAACCGTCGCCCACA [SEQ ID NO: 4], TAAACCTCAAAGAAA [SEQ ID NO: 5] GTAAGGTCATCGATA [SEQ ID NO: 6]. Compositions consisting of two or more ribozymes specific for hepatitis C virus RNA is also provided.
    • 提供了抑制丙型肝炎病毒RNA复制或表达的方法。 该方法包括将丙型肝炎病毒RNA特异性的两种或更多种核酶引入感染丙型肝炎病毒的细胞中。 丙型肝炎病毒RNA特异性的核酶可以特异性切割丙型肝炎病毒5'非编码序列,衣壳序列,NS-5序列或丙型肝炎病毒RNA任何其他保守区域的丙型肝炎病毒RNA。 也可以选择核酶以便对病毒基因组的相反链具有特异性。 还提供了一种抑制丙型肝炎病毒RNA复制或表达的方法,其包括将感染丙型肝炎病毒的细胞引入至少一种对丙型肝炎病毒特异性的核酶,其选自GGGAGGTCTCGTAGA [SEQ ID NO:1 ],GCACCATGAGCACGA [SEQ ID NO:2],CCCACAGGACGTCAA [SEQ ID NO:3],CAACCGTCGCCCACA [SEQ ID NO:4],TAAACCTCAAAGAAA [SEQ ID NO:5] GTAAGGTCATCGATA [SEQ ID NO:6]。 还提供了由丙型肝炎病毒RNA特异性的两种或更多种核酶组成的组合物。
