The decrease in relapse risk was likely due to a decrease in attention to the stimuli over the course of repeated engagement in the alternative behavior. However, this previous procedure was time consuming and did not mirror the procedure we used to observe changes in relapse risk. This study aimed at replicating the previous relationship between the duration of engaging in an alternative behavior and shift in stimulus generalization for drinking using a procedure that allows longitudinal analysis over time and is consistent with other procedures we have developed. Rats were trained to respond for ethanol in the presence of one stimulus (16 kHz tone; food Fixed Ratio (FR)150 and ethanol FR5), and for food in the under another stimulus (8 kHz tone; food and ethanol FR5). Then, recovery-like sessions with food predominant responding occurred in the presence of only the low-cost food stimulus. During these sessions, rats were exposed to non-reinforced graded stimuli alternation from 8 to 16 kHz alternating with the reinforced low-cost food stimulus. The number of responses on each (food and ethanol) lever before completing 5 responses on either lever was the main measure. Consistent with the earlier procedure, the current procedure showed that graded variation of tone from 8 to 16 kHz produced a graded increase in responding for ethanol compared to responding for food. In addition, longer periods of engaging in recovery-like responding shift the generalization function downwards. This procedure confirms the earlier pattern of stimulus generalization over longer periods of behavior consistent with recovery. This strengthens our hypothesis that shifts in attention to alcohol-related stimuli are important to the development of relapse resistance during recovery.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"121 ","pages":"Pages 161-167"},"PeriodicalIF":2.5,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142373689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 <em>FKBP5</em> gene, known to modulate the stress response, is particularly relevant in this context. We postulate that alcohol-induced methylation of the <em>FKBP5</em> 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 <em>FKBP5</em> 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 <em>FKBP5</em> 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 <em>FKBP5</em> methylation as a candidate mediator of the increased vulnerability to mood disorders following early postnatal alcohol exposure.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"123 ","pages":"Pages 11-17"},"PeriodicalIF":2.5,"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":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study used <em>in vivo</em> 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 min for 2.5 h, 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. <em>In vivo</em> microdialysis enables concurrent sampling of brain metabolites during oral ethanol administration, contributing insights into metabolite dynamics.

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.</div></div>","PeriodicalId":7712,"journal":{"name":"Alcohol","volume":"123 ","pages":"Pages 87-99"},"PeriodicalIF":2.5,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142115815","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}
