Analysis of gene expression in separate, non-socially tested subjects revealed that withdrawal from repeated binge episodes during adolescence increased AVP gene expression in the HYP of males and decreased it in females. Males also displayed increased AVP and OXTR gene expression during acute withdrawal from repeated binge episodes in the CeA, with these changes persisting into adulthood.

Many investigators support the theory of a reciprocal relationship between disrupted circadian rhythms, sleep patterns, and alcohol usage. However, in human studies it is difficult to disentangle other factors (i.e. lifestyle, psychiatric, genetic) when determining what is causal in the relationship between substance use and sleep/activity disruptions. To this end, we used an animal model of adolescent alcohol exposure whereby male and female Wistar rats are exposed to 5 weeks of intermittent alcohol vapor during adolescence (P22-P57). Five days after ethanol vapor rats were allowed to select to drink alcohol or water in a two-bottle choice procedure for a period of 5 h, 4 days a week for 6 weeks. Activity data was collected using a “Fitbit-like” device during vapor exposure, during acute withdrawal, and after 3 weeks of protracted withdrawal. Significant changes in rest/wake activity and circadian measures were seen during 24-h withdrawal and after 3 weeks of withdrawal. Four weeks following withdrawal, the effects of the dual orexin antagonist, Daridorexant, (DAX 30 mg, 100 mg, or vehicle control), on alcohol drinking and rest and activity rhythms were assessed over a 24 h period. Both daridorexant doses led to changes in circadian measures and rest/wake activity patterns. These results showed that daridorexant reduced activity, but it did not improve rest quality as measured by the mean inactive episode duration and inactive fragmentation ratio. Additionally, we did not find a significant difference in drinking behavior in animals treated with the orexin antagonist. Thus, it appears that data from this animal model do not support the use of this drug to improve adolescent alcohol-induced sleep disturbance and/or to decrease alcohol drinking.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"124 ","pages":"Pages 35-46"},"PeriodicalIF":2.5,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143054176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
