Epigenetics Glossary

Adipogenesis: Process of cell differentiation by which fat cells (i.e., adipocytes) are generated from precursor cells.

AMP/ATP ratio: Ratio of adenosine monophosphate (AMP) to adenosine triphosphate (ATP) in the cell; ATP supplies the energy needed for many biochemical reactions; therefore, the AMP/ATP ratio reflects the cell’s energy level.

Apoptosis: Series of biochemical reactions occurring...

Epigenetic Targets for Reversing Immune Defects Caused by Alcohol Exposure

Extensive clinical and experimental data suggest that alcohol consumption has dose-dependent modulatory effects on the immune system that influence the two arms of the immune response (i.e., innate and adaptive immune responses). In many other organ systems, such as the brain and liver, alcohol consumption has been shown to alter factors that can modify gene expression without changing the DNA...

Genetic and Environmental Determinants of Stress Responding

The development of alcohol dependence is a complex process influenced by both genetic and environmental risk factors (Prescott and Kendler 1999). The relative contributions of genetic and environmental influences fluctuate across development. During adolescence the initiation of alcohol use is strongly influenced by environmental factors (Dick et al. 2007; Heath et al. 1997; Karvonen 1995...

Alcohol and Stress in the Military

Problematic alcohol use within the United States military has been linked to substantial financial and productivity losses. Data from 2006 revealed that excessive alcohol consumption cost the U.S. military $1.12 billion per year (Harwood et al. 2009). Regarding medical expenditures, studies have found that excessive alcohol use by military members results in an annual cost of $425 million...

Overview: Stress and Alcohol Use Disorders Revisited

In the 13 years since Alcohol Research & Health (now titled Alcohol Research: Current Reviews) first visited the topic of “Alcohol and Stress” (see Vol. 23, No. 4, 1999), there has been a sustained flow of new information in the field prompting us to publish this updated edition. Indeed, one could argue that this second look at the topic is long overdue. An entirely new lexicon of terms1 has been...

The Effects of Stress on Alcohol Consumption

This issue of Alcohol Research: Current Reviews focuses on the impact of stress on alcohol consumption. The significance of stress on alcohol abuse recently has been reemphasized by the alcohol use problems following posttraumatic stress disorder, such as those seen with some combat veterans. Behavior is described as an interaction between genetic constitution and environmental influences. Of the...

Stress and the HPA Axis: Role of Glucocorticoids in Alcohol Dependence

Stress, generally defined as any stimulus that disrupts the body’s internal balance (i.e., physiological homeostasis), has long been suggested to be an important correlate of uncontrolled alcohol consumption or relapse to drinking following a period of abstinence. Large epidemiological studies have reported that a variety of stressors are associated with increased alcohol consumption and binge...

Stress and Alcohol: Epidemiologic Evidence

Exposure to varying forms of stress is an integral life experience that can provoke a variety of reactions. In research on alcohol, drug, and psychiatric disorders, the term “stress” often is understood to indicate any experience denoting adversity (Dohrenwend 2000). Stress exposures consist of external stimuli that are threatening or harmful; elicit fear, anxiety, anger, excitement, and/or...

Stress, Epigenetics, and Alcoholism

Alcoholism is a complex disorder characterized by compulsive alcohol seeking and consumption that also is impacted by related psychiatric states, such as anxiety (Koob 2003; Pandey 2003). Both environmental and genetic factors influence alcohol drinking patterns and may increase susceptibility to the development of alcohol addiction (Cloninger 1987; Crabbe 2002). The presence or development of...
