title: Future directions in alcoholism research. Genomics and gene transfer.
abstract: Alcohol affects the process by which genes direct the synthesis of proteins (i.e., expression). Therefore, patterns of gene expression in the presence of alcohol can help scientists identify the specific molecular sites of alcohol's actions within the brain. New technologies can detect and quantify changes in the expression of thousands of genes simultaneously by scanning microscopic gene arrays applied to glass or silicon chips an inch or so square. However, genes whose activity is altered in the presence of alcohol may either be contributing to alcoholism development or may be reacting to alcohol's presence. This question can be researched by observing the effects of manipulating the level of specific gene products. One way to accomplish this end is by means of viruses that have been engineered to express a specific gene in infected cells. This technique has been applied successfully in studying addictive behaviors. It is suggested that patterns of gene expression may become a diagnostic tool, with different disease states being characterized by distinct expression profiles.
