DESCRIPTION:

Chronic ethanol - Ethanol vs. Control DNA microarray Change in gene expression - Class II Alcoholics were classified based on the quantity of alcohol consumed, according to the National Health and Medical Research Council (NHMRC) (>80 g of alcohol per day), instead of the criteria established by the American Psychiatric Association (DSM-IV) or the World Health Organization (ICD-10). Many alcoholic patients in this study consumed significantly more than 80 g / day for most of their adult life. Cerebral atrophy was observed in three alcoholic cases. All alcoholic cases included in our Axon GenePix 4.0 software; partial least squares (PLS) statistical procedure; linear discriminant analysis (LDA) procedure for prediction analysis. PLS and LDA analysis were performed using in JMP IN software; principal component analysis (PCA) used STATISTICA software. Results reflect the combined dataset: Class I genes were qualitatively different, that is, they were predominantly detected in one group but not the other. They represent those that were more likely turned off or turned on as a result of alcohol abuse. Class II genes were consistently detected in both groups. They represent consistently expressed genes for which quantitative differences in expression could be determined. (NIF Method ID 157)

ABSTRACT:

Alcohol dependence is characterized by tolerance, physical dependence, and craving. The neuroadaptations underlying these effects of chronic alcohol abuse are likely due to altered gene expression. Previous gene expression studies using human post-mortem brain demonstrated that several gene families were altered by alcohol abuse. However, most of these changes in gene expression were small. It is not clear if gene expression profiles have sufficient power to discriminate control from alcoholic individuals and how consistent gene expression changes are when a relatively large sample size is examined. In the present study, microarray analysis (approximately 47,000 elements) was performed on the superior frontal cortex of 27 individual human cases (14 well characterized alcoholics and 13 matched controls). A partial least squares statistical procedure was applied to identify genes with altered expression levels in alcoholics. We found that genes involved in myelination, ubiquitination, apoptosis, cell adhesion, neurogenesis, and neural disease showed altered expression levels. Importantly, genes involved in neurodegenerative diseases such as Alzheimer\'s disease were significantly altered suggesting a link between alcoholism and other neurodegenerative conditions. A total of 27 genes identified in this study were previously shown to be changed by alcohol abuse in previous studies of human post-mortem brain. These results revealed a consistent re-programming of gene expression in alcohol abusers that reliably discriminates alcoholic from non-alcoholic individuals. PUBMED: 16292326
