Outline of Research at the Start

B型慢性肝炎は,肝臓にB型肝炎ウイルスが感染し,増殖することにより発症します.放置すれば,肝硬変及び肝細胞癌といった合併症を引き起こすことがあります.私達は,B型肝炎ウイルスの増殖を抑える物質の一つに,microRNA-6126があることを報告しました.本研究では,microRNA-6126がB型肝炎ウイルスの増殖を抑える際のメカニズムを解明すべく,microRNA-6126により発現が抑えられる遺伝子の同定を試みたいと考えています.

Outline of Final Research Achievements

We found that transfection of miR-6126 suppressed the expression of NTCP, suggesting that miR-6126 may inhibit HBV infection of hepatocytes. This suggests that miR-6126 may inhibit HBV infection of hepatocytes. Next, we searched for the target gene of miR-6126, which was not possible due to time and budget constraints. These results were submitted to Microbiology Spectrum, a journal of the American Society for Microbiology, and are now in major revision.

Academic Significance and Societal Importance of the Research Achievements

microRNAはヒトの体内にもともと存在する物質です.本研究においては,microRNAのうちの一つであるmiR-6126が,HBVの感染を抑制される可能性が示唆されました.HBVの感染メカニズムとその治療方法の開発に寄与する成果です.
