Using Genetically Engineered Animal Models in the Postgenomic Era to Understand Gene Function in Alcoholism

During the first decade of the new millennium, remarkable advances in technology allowed investigators in all areas of biological research to collect massive amounts of genetic data at an unprecedented rate. The genomics revolution, which began with the sequencing of the human genome, was the basis for efforts such as the 1,000 Genomes Project (http://www.1000genomes.org/) that strive to compile a...

Natural Recovery by the Liver and Other Organs After Chronic Alcohol Use

Introduction

A vast body of evidence from human studies and animal research clearly indicates that chronic, heavy alcohol consumption causes structural damage and/or disrupts normal organ function in virtually every tissue of the body. In heavy consumers of alcohol, the liver is especially susceptible to alcohol-induced injury.1,2 Additionally, several other organs—including the gastrointestinal...

Drinking Over the Lifespan: Focus on College Ages

Approximately 41 percent of 18- to 24-year-olds are enrolled in a postsecondary degree-granting institution (National Center for Education Statistics 2013). As a group, college students, and particularly those at residential colleges (Presley et al. 2002), often drink heavily and experience myriad associated negative consequences. This selective review discusses the special characteristics of the...

Patterns of Cannabis and Alcohol Co-Use: Substitution Versus Complementary Effects

Introduction

Use of alcohol and related problems cause significant global and individual health-related harms, and alcohol use is currently the third-leading cause of preventable death in the United States.1,2 Alcohol and cannabis are among the most commonly used psychoactive substances in the United States.3 Although concurrent use of alcohol and cannabis (i.e., co-use: defined as using both...

Alcohol-Related Disparities Among Women: Evidence and Potential Explanations

Although research on alcohol-related disparities among women is a highly understudied area, evidence shows that racial/ethnic minority women, sexual minority women, and women of low socioeconomic status (based on education, income, or residence in disadvantaged neighborhoods) are more likely to experience alcohol-related problems. These problems include alcohol use disorder, particularly after...

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...
