Journal ArticleDOI
The core protein of hepatitis C virus induces hepatocellular carcinoma in transgenic mice.
Kyoji Moriya,Hajime Fujie,Yoshizumi Shintani,Hiroshi Yotsuyanagi,Takeya Tsutsumi,Kotaro Ishibashi,Yoshiharu Matsuura,Satoshi Kimura,Tatsuo Miyamura,Kazuhiko Koike +9 more
TL;DR: It is indicated that the HCV core protein has a chief role in the development of HCC, and that these transgenic mice provide good animal models for determining the molecular events in hepatocarcinogenesis with HCV infection.
Journal ArticleDOI
Hepatitis C virus infection and diabetes: direct involvement of the virus in the development of insulin resistance
Yoshizumi Shintani,Hajime Fujie,Hideyuki Miyoshi,Takeya Tsutsumi,Kazuhisa Tsukamoto,Satoshi Kimura,Kyoji Moriya,Kazuhiko Koike +7 more
TL;DR: The ability of insulin to lower the plasma glucose level in the HCV transgenic mice was impaired, as observed in chronic hepatitis C patients, providing a direct experimental evidence for the contribution of HCV in the development of insulin resistance in human HCV infection, which finally leads to theDevelopment of type 2 diabetes.
Journal Article
Oxidative Stress in the Absence of Inflammation in a Mouse Model for Hepatitis C Virus-associated Hepatocarcinogenesis
Kyoji Moriya,Kiyotaka Nakagawa,Tomofumi Santa,Yoshizumi Shintani,Hajime Fujie,Hideyuki Miyoshi,Takeya Tsutsumi,Teruo Miyazawa,Kotaro Ishibashi,Toshiharu Horie,Kazuhiro Imai,Toru Todoroki,Satoshi Kimura,Kazuhiko Koike +13 more
TL;DR: The HCV core protein alters the oxidant/antioxidant state in the liver in the absence of inflammation and may thereby contribute to or facilitate, at least in part, the development of HCC in HCV infection.
Journal ArticleDOI
Persistent viremia after recovery from self‐limited acute hepatitis B
Hiroshi Yotsuyanagi,Kiyomi Yasuda,Shiro Iino,Kyoji Moriya,Yoshizumi Shintani,Hajime Fujie,Takeya Tsutsumi,Satoshi Kimura,Kazuhiko Koike +8 more
TL;DR: The data suggest that the replication of HBV may persist in some organs, most likely in the liver or peripheral blood cells, for a long period after recovery from acute hepatitis B, and the data indicate the possible transmission ofHBV from organ transplantation donors who exhibit serological markers of past infection only.
Journal ArticleDOI
Interaction of hepatitis C virus core protein with retinoid X receptor α modulates its transcriptional activity
Takeya Tsutsumi,Takeya Tsutsumi,Tetsuro Suzuki,Takashi Shimoike,Ryosuke Suzuki,Kyoji Moriya,Yoshizumi Shintani,Hajime Fujie,Yoshiharu Matsuura,Yoshiharu Matsuura,Kazuhiko Koike,Tatsuo Miyamura +11 more
TL;DR: Results suggest that modulation of RXRα‐controlled gene expression via interaction with the core protein contributes to the pathogenesis of HCV infection.
