Outline of Final Research Achievements |
We investigated the role of long non-coding RNAs in HCV infection. The analysis on RNA of HCV-infected cultured hepatocytes by a next generation sequencer revealed that the RNA level of one of long non-coding RNAs, HULC, increased. The increase of HULC RNA level was observed not only in HCV-infected cultured hepatocytes, but also in an HCV-infected chimpanzee and a HCV-infected mouse. The knockdown of HCV by siRNA suppressed HCV replication as well as infectious virus production in HCV-infected cultured hepatocytes. This effect seemed to occur through the suppression of a translation step among HCV life cycles. Several recent reports show that HULC has the ability to promote hepatocarcinogenesis, therefore, the result of this study suggests a mechanism of hepatocarcinogesis due to HCV infection through HULC.
