10. The results showed that, while both the 118AA and 118GG mice demonstrated robust avoidance of the heroin-paired saccharin cue following daily taste-drug pairings, only the 118AA mice suppressed intake of the heroin-paired saccharin cue when 48h elapsed between each taste-drug pairing

11. There was no association between OPRM1 SNPs and oral pain sensitivity.

14. Possession of the OPRM1 minor allele, 118G and lower mother-child language style matching were both associated with greater Separation Anxiety Disorder symptoms.

15. SNP rs1799971 related to hypnotizability

16. findings suggest that there may not be an association between OPRM1 rs1799971 genotype and alcohol consumption or sensitivity in individuals of European ancestry.

17. the present findings on OPRM1 and OPRL1 methylation together with our previous study on OPRK1 and OPRD1, suggest an epigenetic involvement of the opioid system in AD, and a potential diagnostic value of opioid receptor methylation for AD.

18. ABIN-1 negatively regulates MOR function in vitro and in vivo

19. Cyclopeptide Dmt-[D-Lys-p-CF3-Phe-Phe-Asp]NH2, a novel G protein-biased agonist of the mu opioid receptor.

20. Higher methylation levels within the infants at the -18 (11.4% vs 4.4%, P = .0001), -14 (46.1% vs 24.0%, P = .002) and +23 (26.3% vs 12.9%, P = .008) CpG sites were associated with higher rates of infant pharmacologic treatment. Higher levels of methylation within the mothers at the -169 (R = 0.43, P = .008), -152 (R = 0.40, P = .002) and +84 (R = 0.44, P = .006) sites were associated with longer infant length of stay.

Mouse (Murine) Opioid Receptor, mu 1 (OPRM1) interaction partners

1. Results provide evidence that Oprm1 is involved in hyperalgesia induced by chronic morphine and its metabolite morphine-3-glucuronide.

2. These findings indicate that inhibition of mu-opioid-receptor-associated V1bR provides an approach for enhancing morphine analgesia without increasing analgesic tolerance

3. Study showed that MCRT increased colonic contraction via mu- and delta- opioid receptors.

4. Before behavioral training, mice lacking Oprm1 show perseverative behavior in the Y-maze and severe deficit in social interaction. Behavioral intervention durably relieved social interaction deficit in Oprm1-/- mice.

5. Phosphorylation-deficient Oprm1 improves analgesia and diminishes tolerance but worsens opioid side effects.

6. 3.5 A resolution cryo-electron microscopy structure of the mu-opioid receptor (muOR) bound to the agonist peptide DAMGO and nucleotide-free Gi; these results shed light on the structural features that contribute to the Gi protein-coupling specificity of the microOR

7. Suggest that peripheral and central MOR and central KOR may be involved in the modulation of scratching behaviour in imiquimod-treated mice.

8. Results demonstrate that MOR-dependent behavioral effects of BPN including pain sensitivity, locomotor hyperactivity and approach behavior in the NIH test, are modified by genetic variation in the A112G SNP with the A carrier being most responsive to drug effects.

9. The CeA was subsequently targeted with bilateral infusions of the MOR antagonist naloxonazine, which significantly reduced sodium appetite in mice. The CeA is therefore identified as a key node in the circuit that contributes to sodium appetite. Moreover, endogenous opioids, acting via MOR, within the CeA promote this form of appetitive behavior

10. Our data demonstrate that the main receptor for morphine predominantly shapes the so-called reward/aversion circuitry, with major influence on negative affect centers.
