Rat insulinoma gene (rig) was first isolated from a rat insulinoma cDNA library (1). Homologues of rig were also isolated from human (2), hamster (2), mouse (3), chicken (3) and Xenopus laevis (3) cDNA libraries. The amino acid sequences of isolated rig in the mammals and bird were completely conserved (100%). Using immunological methods, Kitagawa etal. (4) demonstrated that rig is in fact enco...

Vitamin A can significantly decrease measles-associated morbidity and mortality. Vitamin A can inhibit the replication of measles virus (MeV) in vitro through an RARα- and type I interferon (IFN)-dependent mechanism. Retinoid-induced gene I (RIG-I) expression is induced by retinoids, activated by MeV RNA and is important for IFN signaling. We hypothesized that RIG-I is central to retinoid-media...

Protein ubiquitination plays an essential role in the regulation of retinoic acid-inducible gene I (RIG-I) activation and the antiviral immune response. However, the function of the opposite process of deubiquitination in RIG-I activation remains elusive. In this study, we have identified the deubiquitinating enzyme ubiquitin-specific protease 4 (USP4) as a new regulator for RIG-I activation th...

The caspase recruitment domain (CARD) of intracellular adaptors and sensors plays a critical role in the assembly of signaling complexes involved in innate host defense against pathogens and in the regulation of inflammatory responses. The cytosolic receptor retinoic acid-inducible gene-I (RIG-I) recognizes viral RNA in a 5'-triphosphate-dependent manner and initiates an antiviral signaling cas...

Exogenous nucleic acids induce an innate immune response in mammalian host cells through activation of the retinoic acid-inducible gene I (RIG-I). We evaluated RIG-I protein for RNA binding and ATPase stimulation with RNA ligands to investigate the correlation with the extent of immune response through RIG-I activation in cells. RIG-I protein favored blunt-ended, double-stranded RNA (dsRNA) lig...

RIG-I senses intracellular virus-specific nucleic acid structures and initiates an antiviral response that induces interferon (IFN) production, which, in turn, activates the transcription of RIG-I to increase RIG-I protein levels. Upon intracellular poly(I:C) stimulation, however, the levels of RIG-I protein did not correlate with the expression patterns of RIG-I transcripts. When the ISG15 con...

Abstract Energy storage systems are an important component of the energy transition, which is currently planned and launched in most developed developing countries. The article outlines development electric system for drilling based on electric-chemical generators. Description generalization given main objectives this when used rigs isolated within a single pad, whether these fed from diesel ge...
