Laboratory: Laboratory of Addiction Genetics
Dr. Bryant is the Director of the Laboratory of Addiction Genetics. Dr. Bryant’s research program is focused on determining the genetic basis of behavioral and molecular traits relevant to substance dependence in mice. The ultimate goal is to improve our understanding of the neurobiological mechanisms of addiction and to translate these findings toward treatment and prevention strategies in humans. A current focus is to determine the genetic basis of the rewarding properties of opioids in mice by combining quantitative trait locus (QTL) analysis of behavior and gene expression in genetic reference populations that yield high resolution QTLs. This multi-pronged approach to gene mapping will accelerate the nomination of candidate genes for validation via direct gene targeting. A separate focus with regard to functional characterization of candidate genes is the dissection of the hypothesized opposing roles of casein kinase-1 (CK-1) isoforms in regulating dopaminergic signaling and the motivational properties of drugs of abuse. Last, Dr. Bryant has a longstanding interest in deciphering the neurobiological basis of the “placebo effect”, a phenomenon that has been hypothesized to be mediated by the reward expectation. He plans to develop and apply a forward genetic analysis toward Pavlovian conditioning mouse models across a variety of conditions that are notoriously sensitive to the placebo effect, including pain, anxiety, depression, and Parkinson’s Disease.
January 6, 2015: Olga Lacki (Boston University Junior, Neuroscience Major) has once again received stipend support from BU’s UROP program for undergraduate research. Olga will continue to investigate the role of Csnk1e in signaling and addiction traits in response to drugs of abuse. Congratulations to Olga and a thank you to UROP for continuing to fund the research in our lab!
January 5, 2015: Dr. Bryant received the Jack Spivack Excellence in Neurosciences Research Award at Boston University which recognizes and supports the research of an outstanding faculty member at Boston University School of Medicine who is pursuing neurosciences research. Award recipients shall be conducting either clinical or basic neurosciences research in the areas of Parkinson’s, Alzheimer’s, Chronic Traumatic Encephalopathy and/or other neurological disorders.
December 16, 2014: Stacey Kirkpatrick’s manuscript, “Behavioral architecture of opioid reward and aversion in C57BL/6 substrains” was accepted for publication in Frontiers in Behavioral Neuroscience. Here, Stacey applied factor analysis toward multiple behaviors that were assessed in the conditioned place preference/aversion paradigm (CPP/CPA) and identified novel relationships that account for behavioral variation in oxycodone reward versus naloxone aversion. These results enhance our understanding of the behavioral structure of motivated behavior and provide a novel approach to assessing the genetic basis of substance abuse liability.
October 21, 2014: Dr. Bryant’s symposium proposal, “Genomic and neurobiological studies of RNA binding proteins in complex traits relevant to psychiatric disorders”, has been accepted for the 2015 Winter Conference on Brain Research in Big Sky, MA, to be held January 24-29.
July 25, 2014: Lisa Goldberg, Senior Graduate Student and Ph.D. Candidate in the Laboratory of Addiction Genetics, was accepted into the Short Course on the Genetics of Addiction at The Jackson Laboratory (http://courses.jax.org/2014/addiction.html) and was awarded a $1200 scholarship to attend the course by the National Institute on Drug Abuse.
June 20, 2014: Neema Yazdani, Graduate Student and Ph.D. Candidate in the Laboratory of Addiction Genetics, was accepted into the Short Course on the Genetics of Addiction at The Jackson Laboratory (http://courses.jax.org/2014/addiction.html).

TTPAS has generously agreed to provide funding for Neema to attend the course.
May 27, 2014: Dr. Bryant was awarded an R03 from NIDA, “Mapping G x E Interactions for Addiction Traits in a Reduced Complexity Cross”. The goal is to use closely related substrains of C57BL/6 mice to map gene by environment interactions in opioid reward, tolerance, and dependence caused by social drug cues of the cage mates. The findings gleaned from these studies will aid in understanding how the social context of the drug environment can potentially interact with one’s genome to influence behavioral traits that comprise addiction.

January 7, 2014: Alexis Washburn, a freshman undergraduate researcher in the Laboratory of Addiction Genetics, won a competitive Undegraduate Research Opportunity Program (UROP) Grant Award at Boston University for the Spring 2014 semester. This award includes both a stipend and money to help cover research costs. Alexis will have the opportunity to present her research at the Undergraduate Research Symposium in the fall. Alexis’s project involves using QTL mapping to identify novel genetic factors influencing compulsive eating in mice and has relevance toward understanding the genetic and biological mechanisms of eating disorders in humans. The long-term goal is to develop new avenues for prevention and treatment of these highly lethal, neuropsychiatric disorders.
