Phosphatidylinositol 3-kinase (PI3K) is critical player in cell proliferation and survival. The effects of LY294002 and wortmannin, inhibitors of PI3K, on nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in lipoploysaccharide (LPS)-induced Raw 264.7 cells were investigated. Significant inhibition of LPS-induced protein kinase B (PKB, Akt) phosphorylation occurred...
There are many mutations in the gene encoding Hepatitis B virus (HBV) core antigen of chronic active hepatitis patients, and such mutations are most likely to be related to the severity of disease. Here, we constructed plasmids containing wild-type and deletion type of HBV core gene (HBc) to develop an experimental DNA vaccine and to compare immunogenicity of two types of HBc vaccine. Twenty-nine...
