Cytoplasmic viral RNAs with 5' triphosphates (5'ppp) are detected by the RNA helicase RIG-I, initiating downstream signaling and alpha/beta interferon (IFN-alpha/beta) expression that establish an antiviral state. We demonstrate here that the hepatitis C virus (HCV) 3' untranslated region (UTR) RNA has greater activity as an immune stimulator than several flavivirus UTR RNAs. We confirmed that ...

coronary artery disease (cad) is the leading cause of mortality in many parts of the world. genome-wide association studies (gwas) have identified several genetic variants associated with cad in low-density lipoprotein receptor (ldlr) locus. this study was evaluated the possible association of genetic markers at ldlr locus with cad irrespective to lipid profile and as well as the association of...

the association of rs10818488 snp located in traf1/c5 region with rheumatoid arthritis (ra), has been picked up by genome-wide association studies. independent studies in different populations revealed inconsistent results. the aim of this study was to investigate the possible association of this snp with ra in iranian population. a total of 362 cases and 422 healthy controls were recruited in ...

introduction: hepatitis b is a potentially life-threatening infection that causes acute infection and chronic hepatitis with progression to cirrhosis and hepatocellular carcinoma (hcc). interleukin-12 (il12) is responsible for activation of th1 immune responses, leading to possible clearance of hbv infection from the host’s body. the host’s immune-genetic background plays an important role in t...

Three sequences in the vicinity of poly (A) addition sites are conserved among vertebrate mRNAs. We analyze the effects of single base changes in each position of AAUAAA and in the nucleotide to which poly (A) is added on 3' end formation in vitro. All 18 possible single base changes of the AAUAAA sequence greatly reduce addition of poly (A) to RNAs that end at the poly (A) addition site, and p...

tumor necrosis factor alpha-inducible protein 3 (tnfaip3) gene polymorphisms have been reported to be associated with the susceptibility to several immune-related diseases. here we investigated the effect of tnfaip3 gene polymorphisms on the risk of allergic rhinitis (ar) in a chinese han population. the case-control study included 540 ar patients and 524 healthy controls. genotyping for tnfaip...

ankylosing spondylitis (as) is an inflammatory arthritis, which affects mainly spine and sacroiliac joints. according to recent studies, erap1 is the second most common candidate gene for  as susceptibility after hla-b27. the  aim of this study was to  determine the association of erap1 gene polymorphisms with as in iranian population. the study group comprised 387 iranian as patients and 316 h...

background: coronary artery disease (cad) is a multifactorial and heterogenic disease. recently, genome-wide association studies have reported that rs1333040 (c/t) and rs1004638 (a/t) single nucleotide polymorphisms (snps) in the 9p21 locus have very strong association with cad. this study aimed to examine these associations in southwest of iran. methods: blood samples were collected from 200 c...
