Meeting humans is an everyday experience for most companion dogs, and their behavior in these situations and its genetic background is of major interest. Previous research in our laboratory reported that in German shepherd dogs the lack of G allele, and in Border collies the lack of A allele, of the oxytocin receptor gene (OXTR) 19208A/G single nucleotide polymorphism (SNP) was linked to increa...
Single nucleotide polymorphisms (SNPs) in the OPRM1 gene have been associated with vulnerability to opioid dependence. The current study identifies an association of an intronic SNP (rs9479757) with the severity of heroin addiction among Han-Chinese male heroin addicts. Individual SNP analysis and haplotype-based analysis with additional SNPs in the OPRM1 locus showed that mild heroin addiction...
It has been proposed that genetic factors account for 30%–50% of the risk for cocaine and heroin addiction. The present study was aimed to find out the impact of μ-opioid receptor gene (OPRM1) rs1799971 A > G and rs9479757 polymorphisms on heroin dependence in a sample of southeast Iranian population. This case-control study was done on 123 heroin addicts and 140 non-addicts Iranian male. Genom...
Non-steroidal anti-inflammatory drugs (NSAIDs) identified effective in many diseases. One of which is neurodegenerative diseases including Alzheimer disease (AD). In this study gross alteration of gene expression in AD mice by ibuprofen treatment is investigated via Protein-protein interaction network (PPI) analysis. Expression profiling of microarray dataset GSE67306 was retrieved from GEO dat...
678 October 2014 O PIOID analgesics are the most widely used drugs to treat moderate to severe pain. High individual variability has been reported in both pain intensity and in response to pharmacological analgesia. Furthermore, patients’ responses vary for both analgesic efficacy and side effects to different opioids, despite the fact that most clinically used opioids are selective for μ-opioi...

CONTEXT Clinical trials have suggested a modest effect of naltrexone as a pharmacotherapy for alcoholism, and a recent study has suggested that the effects may be moderated by variations in the mu-opioid receptor gene (OPRM1). However, the mechanism by which naltrexone may be differentially effective as a function of the OPRM1 genotype is unclear. OBJECTIVES (1) To replicate and expand on the...
BACKGROUND No opioid receptor, mu 1 (OPRM1) gene polymorphisms, including the functional single nucleotide polymorphism (SNP) rs1799971, have been conclusively associated with heroin/other opioid addiction, despite their biological plausibility. We used evidence of polymorphisms altering OPRM1 expression in normal human brain tissue to nominate and then test associations with heroin addiction. ...
A single nucleotide polymorphism (SNP) in the human mu-opioid receptor gene (OPRM1 A118G) has been widely studied for its association in a variety of drug addiction and pain sensitivity phenotypes; however, the extent of these adaptations and the mechanisms underlying these associations remain elusive. To clarify the functional mechanisms linking the OPRM1 A118G SNP to addiction and analgesia p...
The increase in opioidergic tone by the central administration of morphine, which binds to the mu opioid receptor, is associated with pruritus. Pruritus is a symptom of cholestasis, which appears to result, in part, from increased opioidergic tone; a central mechanism has been proposed. The single nucleotide polymorphism Al18G in exon 1 of the opioid receptor mu 1 (OPRM1) gene, which codes for ...
