In a genome-wide methylation analysis, we recently identified an association of a methylated region in the OPRL1 gene with alcohol-use disorders. METHODS: Here, we investigate the biological basis of this observation by analysing psychosocial stressors, methylation of the OPRL1 gene, brain response during reward anticipation and alcohol drinking in 660 fourteen-year-old adolescents of the IMAGEN study. We validate our findings in marchigian sardinian (msP) alcohol-preferring rats that are genetically selected for increased alcohol drinking and stress sensitivity. RESULTS: We found that low methylation levels in intron 1 of OPRL1 are associated with higher psychosocial stress and higher frequency of binge drinking, an effect mediated by OPRL1 methylation. In individuals with low methylation of OPRL1, frequency of binge drinking is associated with stronger BOLD response in the ventral striatum during reward anticipation. In msP rats, we found that stress results in increased alcohol intake and decreased methylation of OPRL1 in the nucleus accumbens. CONCLUSIONS: Our findings describe an epigenetic mechanism that helps to explain how psychosocial stress influences risky alcohol consumption and reward processing, thus contributing to the elucidation of biological mechanisms underlying risk for substance abuse.

One mechanistic account of these comorbidities is that ASD is characterized by impaired emotion regulation (ER) that results in deficits modulating emotional responses. We assessed neural activation during cognitive reappraisal of faces in high functioning adults with ASD. Groups did not differ in looking time, pupilometry, or subjective ratings of faces during reappraisal. However, instructions to increase positive and negative emotional responses resulted in less increase in nucleus accumbens and amygdala activations (respectively) in the ASD group, and both regulation instructions resulted in less change in dorsolateral prefrontal cortex activation in the ASD group. Results suggest a potential mechanistic account of impaired ER in ASD.

Titre : Reward Circuitry Function in Autism During Face Anticipation and Outcomes Type de document : Texte imprimé et/ou numérique Auteurs : Gabriel S. DICHTER, Auteur ; J. Anthony RICHEY, Auteur ; Alison M. RITTENBERG, Auteur ; Antoinette SABATINO-DICRISCIO, Auteur ; James W. BODFISH, Auteur Année de publication : 2012 Article en page(s) : p.147-160 Langues : Anglais (eng) Mots-clés : Autism Nucleus accumbens Anticipation Functional magnetic resonance imaging Social cognition Reward Index. décimale : PER Périodiques Résumé : The aim of this study was to investigate reward circuitry responses in autism during reward anticipation and outcomes for monetary and social rewards. During monetary anticipation, participants with autism spectrum disorders (ASDs) showed hypoactivation in right nucleus accumbens and hyperactivation in right hippocampus, whereas during monetary outcomes, participants with ASDs showed hyperactivation in left midfrontal and anterior cingulate gyrus. Groups did not differ in nucleus accumbens responses to faces. The ASD group demonstrated hyperactivation in bilateral amygdala during face anticipation that predicted social symptom severity and in bilateral insular cortex during face outcomes. These results add to the growing body of evidence that autism is characterized by altered functioning of reward circuitry. Additionally, atypical amygdala activation during the processing of social rewards may contribute to the development or expression of autistic features.
