Abstract

Human mu-opioid receptor (OPRM1) is the major site for the analgesic action of most opioid drugs such as morphine, methadone and heroin. It was previously reported that a single nucleotide polymorphism (SNP) in exon1 (c.118A-->G) of OPRM1 might modestly alter the affinity in beta-endorphin-Mu interaction. Using denaturing high performance liquid chromatography (DHPLC) the complete coding region of the OPRM1 gene was screened for SNPs in Han-Chinese heroin addicts and normal control. Three novel SNPs were detected, one in exon3, one in intron3 and one in the 3' untranslated region. The SNP c.118A-->G reportedly altered the interaction of Mu receptor with opioid had no statistically significant correlation with heroin addition in Han Chinese. However, addicted subjects with the SNP in intron2 (IVS2 +31G-->A) tended to show much higher heroin intake dosages than those without this SNP. We also observed that individuals carrying both SNP c.118A-->G and IVS2 +31G-->A consumed relatively more drugs compared to other addicts. Thus our study further highlights the importance of studing the various regions of the mu opioid receptor gene, coding as well as non-coding, for genetic markers that may be linked to, or directly contribute to opioid drug-seeking behavior.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The increase in serum prolactin caused by nicotine may be due to nicotine reducing dopamine turnover and release by occupying mu or kappa opioid receptors or cholinergic receptors on dopaminergic cells, leading to over-production of prolactin by lactotroph cells.

    “This might be the ability of nicotine to reduce the turnover and release of dopamine through occupying mu or kappa receptors of endorphins or through cholinergic receptors for nicotine[1920] presented on dopaminergic cells. Local reduction of dopamine could lead to over-production of prolactin by lactotroph cells.[21]”
  • Other mutations in OPRM1 are associated to heroin addiction, pain perception, but also sociality traits.

    “Other mutations in this gene are associated to heroin addiction178, and pain perception179, but also sociality traits180.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
