| Research Abstract |
N-Acetylglucosaminyltransferase V (GnT-V), catalyzing beta1-6 branching in asparagine-linked oligosaccharides, is known to promote cancer metastasis, and its expression is increased in chronic hepatitis (CH) progression. Using GnT-V transgenic (Tg) mice, we found GnT-V prevented hepatic inflammation and fibrosis in a mouse CH model through modulation of lymphocyte and HSC function. Moreover, we also found GnT-V prevented hepatocyte cholesterol accumulation which led to ameliorate hepatocyte sensitivity to inflammation. These results indicated expression of GnT-V in CH would prevent disease progression as a self-defense reaction.
