Myelin Gene Expression: Implications For Alcohol Abuse And Dependence, Sean Farris
Myelin Gene Expression: Implications For Alcohol Abuse And Dependence, Sean Farris
Theses and Dissertations
Acute behavioral responses to ethanol have predictive value for determining an individual's risk of long-term drinking behavior. Although the neurobiology of alcohol abuse is complex, prior studies from our laboratory demonstrated differential myelin-associated gene expression (MAGE) in medial prefrontal cortex (PFC) as one potential mechanism influencing acute ethanol behaviors between C57BL/6J (B6) and DBA/2J (D2) mice. Our laboratory and others have also shown MAGE is reduced in PFC of alcoholics. Herein, I have extended these findings through expression profiling of PFC into chronic models of ethanol self-administration from non-human primates and mice. Together, these results suggest that regulation of MAGE …
Association Tests Of The Opioid Receptor System And Alcohol-Related Traits, Ryan Bennett
Association Tests Of The Opioid Receptor System And Alcohol-Related Traits, Ryan Bennett
Theses and Dissertations
The opioid receptors and their endogenous ligands have long been implicated in a variety of traits including addiction, impulsive behaviors and substance dependence. Using phenotypic measurements collected from the IASPSAD, data from a latent class analysis and data from a SNP array and additional genotyping assays, association and regression tests were performed to determine the effects of common SNPs encoded in the genes of the opioid receptors and ligands on various traits relating to alcohol dependence. Although only one SNP can be reported as significant for substance dependence within alcoholics, there were a few results approaching significance that may offer …
