    摘要： This invention relates to a DNA fragment comprising a base sequence encoding a non-A non-B hepatitis-specific antigen polypeptide, said base sequence being obtained using genetic engineering techniques from non-A non-B hepatitis virus RNA which is isolated directly from blood plasma from non-A non-B hepatitis patients, to an expression vector and a transformant for use in the expression of the DNA fragment, to a single strand DNA sequence for PCR primer, and to use of said polypeptide and said single strand DNA sequence in the detection of the non-A non-B hepatitis virus. The recombinant polypeptide and the single strand DNA sequence for PCR primer make it possible to detect the non-A non-B hepatitis virus with extremely high accuracy.

    摘要： The present inventors focused on siE sequences that have been thought to show RNAi activity against HCV viral RNAs, and mainly selected the D5-50 and D5-197 regions present within the IRES region, and carried on the analysis. As a result, the present inventors successfully identified siRNA sequences that exhibit a more effective RNAi activity against hepatitis C virus RNAs. Furthermore, the siRNAs were demonstrated to have a significant inhibitory effect on HCV propagation in an in vivo system.

    摘要： The main purpose of the present invention is to provide a novel antiviral agent having a useful pharmacological action. The present inventors found that the above-described purpose can be achieved by a complex in which two synthetic RNAs (e.g., poly-I and poly-C) that can together form a double strand are contained in a drug carrier useful for transporting a drug into a cell (e.g., cationic liposome and atelocollagen), and thus the present invention was achieved.

    摘要： The present invention provides a transgenic animal expressing the full-length human hepatitis C virus (HCV) for the purpose of constructing a system for screening for a remedy for human hepatitis C. The present invention is a transgenic hepatitis C model animal, which has the full-length DNA of the hepatitis C virus incorporated therein and can express the full-length HCV gene, and a method of generating a hepatitis C model animal carrying the full-length HCV gene, which comprises introducing a vector containing the full-length DNA of hepatitis C virus into an ES cell, and causing the ES cells to undergo ontogenesis in a pseudo-parent.

    摘要： The present invention aims to provide hepatitis C virus inhibitors capable of inhibiting viral replication in hepatitis C virus-infected cells.The replication of hepatitis C virus can be inhibited and hepatitis C virus-infected cells can be specifically injured by specifically inhibiting BGT-1 or AKR1C1 involved in the replication of hepatitis C virus. Thus, viral inhibitors comprising a substance inhibiting BGT-1 or AKR1C1 are effective for the treatment of hepatitis C.
