Promotion of expression of interferon-stimulated genes in U937 monocytic cells by HIV RNAs, measured using stable isotope labeling with amino acids in cell culture (SILAC)
Type I interferon (IFN) exerts strong antiviral activity, particularly against human immunodeficiency virus (HIV), and although several viral proteins have been shown to deregulate IFN induction, little is kno...

Swine PPAR-γ2 expression upregulated in skeletal muscle of transgenic mice via the swine Myozenin-1 gene promoter
Myozenin-1 (Myoz1) gene-encoded calsarcin-2 protein was expressed exclusively in fast-twitch muscles. Peroxisome proliferator-activated receptor γ2 (PPAR-γ2) is a key regulator of adipocyte diffe...

MicroRNAs regulate the immunometabolic response to viral infection in the liver
25-Hydroxycholesterol induces expression of the microRNAs miR-130b and miR-185 in HCV-infected cells, and these inhibit viral fatty acid desaturation, lipid uptake and biosynthesis, thereby limiting infection....
