Accumulating evidence continues to link certain aspects of the endogenous cannabinoid (EC) system with alcohol dependence, negative-reinforcement learning, and the modulation of stress responses. Specific alterations in brain regions that are related to stress and negative-reinforcement learning have been reported to exist in Cloninger type 1 and type 2 alcoholics. To study possible differences in...
Withdrawal Seizure-Prone (WSP) and Withdrawal Seizure-Resistant (WSR) mouse lines were bidirectionally selectively bred, respectively, to have severe or mild ethanol withdrawal handling-induced convulsions (HICs) after cessation of 3 days of ethanol vapor inhalation. Murine genotypes with severe withdrawal have been found to show low ethanol consumption, and high consumers show low withdrawal. An...
Craniofacial bone dysmorphology is an important but under-explored potential diagnostic feature of fetal alcohol spectrum disorders. This study used longitudinal MicroCT 3D imaging to examine the effect of prenatal alcohol exposure on craniofacial bone growth in a mouse model. C57BL/6J dams were divided into 3 groups: alcohol 4.2% v/v in PMI ® liquid diet (ALC), 2 weeks prior to and during...
Although recent work suggests that the dynorphin/kappa opioid receptor (DYN/KOR) system may be a key mediator in the stress-related effects of alcohol, the regulation of long-term changes associated with protracted withdrawal from ethanol via the DYN/KOR system has yet to be explored. The objective of the present study was to determine the role of the DYN/KOR system in the regulation of anxiety-related...
Preclinical animal models constitute a cornerstone against which the reward processes involved in drug addiction are often studied and dissected. While rodents have traditionally represented the species of choice, a growing body of literature indicates that zebrafish are emerging as a valuable model organism. Specifically, several studies demonstrate that the effects of ethanol at the level of emotional-...
The objective of this study was to detect changes in gene expression in the ventral tegmental area (VTA) following repeated excessive binge-like (‘loss-of-control’) alcohol drinking by alcohol-preferring (P) rats. Adult female P rats (n = 7) were given concurrent access to 10, 20, and 30% EtOH for 4 1-h sessions daily for 10 weeks followed by 2 cycles of 2 weeks of abstinence and 2 weeks of EtOH access...
Alcohol and tobacco are frequently co-abused. Tobacco smoke increases alcoholic steatosis in apoE(−/−) mice. Tobacco smoke contains more than 4000 chemicals, but it is unknown which compounds in tobacco smoke play a major role in increasing alcoholic steatosis.C57BL/J6 mice were intraperitoneally injected with nicotine at 1 mg/kg every day or saline at the same volume as a control and the mice were...
Children with fetal alcohol syndrome (FAS) display striking craniofacial abnormalities. These features are proposed to result from perturbations in the morphology and function of cranial neural crest cells (cNCCs), which contribute significantly to the craniofacial complex. While certain pathways by which this may occur have been suggested, precise teratogenic mechanisms remain intensely investigated,...
