Understanding the relationships between impulsivity and drug use vulnerability may help identify new ways of treating or preventing substance use disorders.
March 2016 A gene variant appears to partially shield people whose behaviors entail high risk for exposure to human immunodeficiency virus (HIV) from becoming infected.
February 2015 Can marijuana use put offspring at heightened risk for opiate addiction, even if the use stops before the offspring are conceived? Results from a recent NIDA-funded study are consistent with other studies suggesting that a parent’s history of drug use, even preconception, may affect a child’s brain function and behavior.
June 2014 Two recent studies suggest that genotyping may enable clinicians to base therapies on individual patients’ potential responsiveness to opioid drugs’ therapeutic effects and vulnerability to their harmful effects.
May 2014 One of NIDA’s goals is to try to understand the individual differences that contribute to whether or not someone who takes a drug will become addicted to it. Dr. Rutter’s research focuses on three types of differences: Environmental, developmental, and genetic and epigenetic.
November 2013 A meta-analysis of 13 genome-wide association studies of African Americans’ smoking patterns confirms the significance of genetic variation in region 15q25.1. The analysis also tentatively implicates several genome locations that have not previously been associated with smoking behaviors.
August 2013 In a surprising finding, male rats who used cocaine sired male offspring who later exhibited blunted responses to the drug. Researchers determined the cause was an epigenetic alteration.
November 2012 NIDA-supported research suggests that glucocorticoid receptor levels during early brain development affect the hard wiring of neural circuits that shape an individual’s basic emotional makeup. In mice, overexpression of the glucocorticoid gene in the first weeks after birth increased anxiety and response to cocaine in adulthood. These findings may help researchers understand the genetic background and the developmental trajectory of addiction.
July 2012 NIDA researchers working with human subjects now have a new resource at their fingertips: the PhenX Toolkit’s new Substance Abuse and Addiction (SAA) Collection. The Toolkit is designed to provide standardized measures, vetted and approved by the field, to help researchers compare and combine data from multiple studies.
