These are neurochemical systems that, if out of balance, could lead to anxiety behavior. This is the first study to investigate whether changes in protein expression in the amygdala nucleus are associated with high anxiety in tinnitus. After inducing and confirming tinnitus in rats using gap-prepulse inhibition of the acoustic startle (GPIAS) and Pre-pulse inhibition (PPI), the Elevated Plus Maze (EPM) and the Open Field Test (OFT) were used to assess anxiety levels in both groups. Subsequently, amygdala tissue samples were collected from both groups and analyzed for NLGN2 and BDNF protein expression. The GPIAS score decreased following sodium salicylate administration in the tinnitus group, while the PPI score did not change. Additionally, the tinnitus group exhibited higher anxiety levels than the control group in both behavioral tests. Moreover, NLGN2 protein expression was increased in the amygdala nucleus of sodium salicylate-induced tinnitus rats compared to controls, while BDNF protein expression was reduced. These findings suggest that increased NLGN2 and decreased BDNF protein levels in the amygdala nucleus contribute to tinnitus-related anxiety and identify these proteins as potential therapeutic targets for tinnitus.</div></div>","PeriodicalId":13195,"journal":{"name":"IBRO Neuroscience Reports","volume":"17 ","pages":"Pages 407-414"},"PeriodicalIF":2.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142662840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rat model of fetal alcohol spectrum disorder (FASD) was initially generated to reflect on the deficits in the first generation, and then those transmitted via the male germline to the unexposed male ones. The pregnant rats were thus divided into four groups, namely, the control group (CTRL) receiving only distilled water (DW), and three groups being exposed to ethanol (20 %, 4.5 g/kg) by oral gavage, during the first 10-day gestation (FG), the second 10-day gestation (SG), and the entire gestation (EG) periods. Subsequent Morris water maze (MWM) tests on male offspring revealed spatial learning deficits during the second and entire gestational periods in both generations. Analysis of antioxidant enzyme activity including glutathione peroxidase (GPx), superoxide dismutase (SOD), and malondialdehyde (MDA), and BDNF gene expression in the hippocampus further highlighted the impacts of prenatal ethanol exposure. The study results demonstrated that prenatal ethanol exposure caused spatial learning/memory deficits during the SG and EG, altered antioxidant enzyme activity, and reduced BDNF gene expression in both generations.
