Epigenetic Control of Gene Expression in the Alcoholic Brain

Whether a specific gene is transcribed or repressed is determined by the specific status (i.e., conformational state) of the complex of chromosomal DNA and proteins (i.e., the chromatin) and by the recruitment of specific proteins (i.e., transcription factors) to regulatory sites on the DNA (Copeland et al. 2010). Chromatin states can change as a result of enzyme-mediated covalent modifications of...

Alcohol and Skeletal Muscle in Health and Disease

Introduction

Alcohol misuse is the most common form of substance misuse and is associated with liver, cardiovascular, and metabolic diseases as well as with infections and cancers.1 Although an estimated 20% to 25% of people who drink heavily develop alcohol-related liver disease,2 40% to 60% of people with alcohol misuse have alcohol-related myopathy.3 Evidence that alcohol use leads to skeletal...

Measuring the Burden - Alcohol’s Evolving Impact

This issue of Alcohol Research: Current Reviews examines the public health impact of alcohol consumption beyond the role of alcohol use disorders alone (Room et al. 2005)—that is, it looks at the burden of disease. Determining impact hinges on accurate and consistent “measurements.” As demonstrated in the articles in this issue, impact typically is estimated based on three elements (Rehm et al...

Recovery in Special Emphasis Populations

Special emphasis populations in the current context can be defined as groups experiencing health disparities resulting in elevated risk to health, safety, and well-being from drinking alcohol. Individuals from marginalized minority populations often encounter barriers to accessing and receiving effective alcohol treatment due to social inequities and disadvantaged life contexts, which also may...

Biology, Genetics, and Environment: Underlying Factors Influencing Alcohol Metabolism

Epidemiological studies have demonstrated that drinking patterns and the prevalence of alcohol-related adverse consequences, including alcohol use disorder (AUD), differ substantially among racial/ethnic groups in the United States. For example, analyses comparing drinking patterns and their consequences among Whites, Blacks, Asians, and Hispanics found the following: Whites have the highest risk...

Epigenetics—New Frontier for Alcohol Research - Editor's Note

The term “epigenetics” is rapidly becoming one of the more important watchwords in the field of alcohol research. Put simply, epigenetics is the study of changes in gene function that occur without a change in the body’s genetic code, instead relying on epigenetic markers on, among others, the DNA and certain nuclear proteins to turn genes “on” and “off.” Epigenetic changes also are brought about...

Drinking Across the Lifespan: Focus on Older Adults

In 2010, when the leading edge of the post–World War II “Baby Boom” reached age 65, the United States began a period of increased growth in its older adult population. By 2030, it is expected that there will be 72.1 million adults age 65 or older living in the United States, almost double the 2008 population. Those older adults will represent 19.3 percent of the U.S. population, compared with 12...

Alcohol and HIV Effects on the Immune System

Alcohol use disorder (AUD) and HIV infection both affect the immune system and frequently coexist in the same person, potentially multiplying the risk of infectious disease. Infectious disease, in turn, continues to be a major health concern and leading cause of morbidity and mortality worldwide, despite major advances in our understanding of the immune system, improvements in sanitation...

Identifying Gene Networks Underlying the Neurobiology of Ethanol and Alcoholism

The multiple genetic, environmental, and behavioral factors that play a role in the development of alcohol use disorders (AUDs) make it difficult to identify individual genes linked to these disorders. Nevertheless, some genetic risk factors (i.e., specific variants) associated with AUDs have been identified within many genes, some of which code for proteins involved in known biological pathways...
