Moreover, maternal alcohol consumption during pregnancy has been linked to the manifestation of mental health disorders, such as depression and anxiety, in subsequent generations. These mood disturbances may be attributed to alterations in protein expressions related to depression and anxiety within the hippocampus. While the precise mechanisms remain elusive, it is likely that pre- and postnatal exposure to alcohol induces changes in hippocampus, potentially through epigenetic modifications. The FKBP5 gene, known to modulate the stress response, is particularly relevant in this context. We postulate that alcohol-induced methylation of the FKBP5 gene disrupts HPA axis function, thereby prompting individuals to anxiety-like and depressive-like behaviors. To investigate this hypothesis, female C57BL/6 pups were subjected to early alcohol exposure via intubation with ethanol mixed in artificial milk from Postnatal Day 3 to Day 20. The intubation control pups were subjected to the same procedures without ethanol or milk, and a non-intubated control group included. Anxiety-like and depressive-like behaviors were assessed using the open field test, plus maze test, forced swim test, and tail suspension test when the pups reached 3 months of age. For epigenetic analysis of the FKBP5 gene, genomic DNA was isolated from hippocampal tissues and subjected to bisulfite conversion to distinguish methylated and unmethylated cytosines. Then, methylation-specific PCR was performed to assess methylation levels. Pups exposed to early postnatal alcohol exhibited increased levels of depression-like behavior and susceptibility to anxiety-like behavior during adolescence, as verified by behavioral assessments. Methylation profiling revealed higher rates of methylation within the stress-associated gene FKBP5 in both the early postnatal alcohol-exposed cohort (13.82%) and the intubation control group (3.93%), in contrast to the control cohort devoid of stress or alcohol exposure. These findings suggest a potential epigenetic mechanism underlying the observed behavioral alterations, implicating FKBP5 methylation as a candidate mediator of the increased vulnerability to mood disorders following early postnatal alcohol exposure.</p>","PeriodicalId":93864,"journal":{"name":"Alcohol (Fayetteville, N.Y.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142156916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used in vivo microdialysis to simultaneously sample ethanol and its metabolites, acetaldehyde and acetate, in the rat striatum following self-administration of ethanol, emphasizing the natural oral exposure route. To enhance the self-administration, rats underwent two-bottle-choice and limited access training. Dialysate samples, collected every 10 minutes for 2.5 hours, were analyzed using gas chromatography with flame ionization detection (GC-FID). The measured time courses of dialysate concentrations of ethanol, acetaldehyde, and acetate provided insights into dynamics of ethanol metabolism. Notably, in a subject with low ethanol consumption (0.29 g/kg), the concentration of acetaldehyde remained below the limit of detection throughout the experiment. However, the acetate concentration was clearly increased after ethanol consumption in this subject and was comparable to that of other rats with higher ethanol consumption. Compared with focusing only on peak values in the time-courses of concentrations of ethanol and its metabolites, calculating areas under curves provided better models of the relationships between ethanol intake and individual ethanol metabolites, as indicated by the r-square values for the linear regressions. This approach of using the area under the curve accounts for both the amplitude and duration of the concentration profiles, reducing the impact of variations in individual drinking patterns. In vivo microdialysis enables concurrent sampling of brain metabolites during oral ethanol administration, contributing insights into metabolite dynamics.

The goal of this study was to understand sex differences in ethanol drinking behavior and define the precise conditions under which sex differences emerge. Consistent with prior work, C57BL/6J females drank more than males under continuous access two-bottle choice conditions. However, using ethanol self-administration - where an operant response results in access to an ethanol sipper for a fixed time period - we found no sex differences in operant response rates or ethanol consumption (volume per body weight consumed, as well as lick behavior). This remained true across a wide range of parameters including acquisition, when the ethanol sipper access period was manipulated, and when the concentration of the ethanol available was scaled. The only sex differences observed were in total ethanol consumption, which was explained by differences in body weight between males and females, rather than by sex differences in motivation to drink. Using dimensionality reduction approaches, we found that drinking behavior in the operant context did not cluster by sex, but rather clustered by high and low drinking phenotypes. Interestingly, these high and low drinking phenotypes in the operant context showed no correlation with those same categorizations in the home cage context within the same animals. These data underscore the complexity of sex differences in ethanol consumption, highlighting the important role that drinking conditions/context plays in the expression of these differences.</p>","PeriodicalId":93864,"journal":{"name":"Alcohol (Fayetteville, N.Y.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142115815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is unclear how alcohol exacerbates PTSD predicaments owing to less characterized pathophysiological mechanisms. Also, studies on pharmacological agents that can effectively reverse PTSD-AUD comorbidity have, to date, been scarce. Hence, we designed a methodological approach to investigate the pathophysiological mechanisms and pharmacological outcomes of morin, a neuroprotective flavonoid in mice. After 7 days of PTSD following single-prolonged stress (SPS) induction in mice, the PTSD mice were exposed to intermittent binge ethanol administration using ethanol (2g/kg, oral gavage) every other day, alongside daily morin (50 and 100mg/kg) or fluoxetine (10mg/kg) from days 8-21. The consequences of PTSD-AUD behavior, hypothalamic-pituitary-adrenal-axis (HPA-axis) dysfunction, neurochemistry, oxidative/nitrergic stress, and inflammation were evaluated in the prefrontal-cortex (PFC), striatum, and hippocampus of mice. The exacerbated anxiety-like behavior, and spatial/non-spatial memory deficits, with general depressive phenotypes and social stress susceptibility by SPS-ethanol interaction, were alleviated by morin and fluoxetine, evidenced by reduced corticosterone release and adrenal hypertrophy. SPS-ethanol exacerbates dopamine, serotonin, and glutamic acid decarboxylase alterations, and monoamine oxidase-B and acetylcholinesterase hyperactivities in the striatum, PFC, and hippocampus, respectively, which were prevented by morin. Compared to SPS-ethanol aggravation, morin prevented TNF-α, and IL-6 release, malondialdehyde and nitrite levels, with improved antioxidant (glutathione, superoxide-dismutase, catalase) levels in the hippocampus, PFC, and striatum. Overall, these findings suggest that AUD exacerbated PTSD might be primarily connected, among other mechanisms, with aggravated HPA-axis dysfunction, upregulated neurochemical degradative enzymes, enhancement of oxidative/nitrergic stress and neuroinflammation, stereo-selectively in the mice brains, which morin abated via the preventive mechanisms.</p>","PeriodicalId":93864,"journal":{"name":"Alcohol (Fayetteville, N.Y.)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141879893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study aimed to replicate associations between sleep and alcohol use, test associations with NRL, and examine indirect associations between sleep health and alcohol use via NRL among 60 underage college students (ages 18-20 years, 77% female) varying in depression and anxiety symptoms. Participants wore Fitbit smartwatches and completed daily diaries measuring sleep and substance use for ∼14 days before completing two computer tasks assessing social (SNRL) and monetary (MNRL) negative reinforcement learning.

Statistical mediation models failed to indicate indirect effects of sleep on alcohol use via SNRL or MNRL performance. Post-hoc exploratory models examining depression and anxiety symptoms as moderators of direct associations indicated several interactions. Positive associations between sleep timing variability and alcohol use were weakened at higher anxiety symptom severity and stronger at higher depression symptom severity. The positive association between SNRL performance and alcohol use was also stronger at higher depression symptom severity. Among students with elevated depression symptoms, variable sleep timing and stronger SNRL performance were independently associated with more alcohol use, but indirect effects were not supported.
