Behavioral And Genomic Characterization Of Scheduled Ethanol Deprivation, Jonathan Warner
Behavioral And Genomic Characterization Of Scheduled Ethanol Deprivation, Jonathan Warner
Theses and Dissertations
Alcoholism is a persistent substance abuse disorder that is associated with negative health, social, and economic outcomes. Treatment strategies for alcohol use disorders are limited, and only three drugs have been approved by the FDA for treatment. Although behavioral therapy and drug combination strategies improve abstinence outcomes, the majority of those in treatment will not achieve long-term abstinence. Therefore, better treatment strategies are needed. While much progress has been made toward understanding the neurobiology of alcoholism, this knowledge has not been effectively translated into treatment strategies. Animal models of alcohol drinking have been crucial to this research effort, but until …
Identification And Characterization Of Ethanol Responsive Genes In Acute Ethanol Behaviors In Caenorhabditis Elegans, Joseph Alaimo
Identification And Characterization Of Ethanol Responsive Genes In Acute Ethanol Behaviors In Caenorhabditis Elegans, Joseph Alaimo
Theses and Dissertations
Alcohol abuse and dependence are complex disorders that are influenced by many genetic and environmental factors. Acute behavioral responses to ethanol have predictive value for determining an individual’s long-term susceptibility to alcohol abuse and dependence. These behavioral responses are strongly influenced by genetics. Here, we have explored the role of genetic influences on acute behavioral responses to ethanol using the nematode worm, Caenorhabditis elegans. First, we explored the role of ethanol metabolism in acute behavior responses to ethanol. Natural variation in human ethanol metabolism machinery is one of the most reported and reproducible associations found to alter drinking behavior. Ethanol …
Ethanol Regulation Of Glucocorticoid Responsive Genes, Blair Costin
Ethanol Regulation Of Glucocorticoid Responsive Genes, Blair Costin
Theses and Dissertations
Glucocorticoid hormones modulate acute and chronic behavioral and molecular responses to drugs of abuse including psychostimulants and opioids. Acute ethanol activates the hypothalamic pituitary adrenal (HPA) axis causing the release of adrenal glucocorticoid hormones, but following chronic ethanol the HPA axis is dysregulated in both humans and rodents. Thus, there is growing evidence that glucocorticoids might also modulate behavioral and molecular responses to ethanol. Previous microarray studies in the Miles’ laboratory have shown that the well-known glucocorticoid responsive gene, Serum and Glucocorticoid-regulated Kinase 1, Sgk1, is prominently up regulated by acute ethanol (2 g/kg) in the prefrontal cortex (PFC) of …
