Ethanol Sustains Phosphorylated Tau Protein Immunofluorescence In The Cultured Neonatal Rat Hippocampus: Implications For Fetal Alcohol Spectrum Disorders, Caleb Seth Bailey Jan 2020

Ethanol Sustains Phosphorylated Tau Protein Immunofluorescence In The Cultured Neonatal Rat Hippocampus: Implications For Fetal Alcohol Spectrum Disorders, Caleb Seth Bailey

Theses and Dissertations--Psychology

Fetal Alcohol Spectrum Disorders (FASDs) are comprised of developmental, behavioral, and cognitive abnormalities caused by prenatal alcohol exposure, affecting an estimated 2%-5% of childrenand costing up to $4 billion annually in the United States alone. Although some behavioral therapies can help, the biochemical mechanisms that underpin FASDs need further elucidation for development of more efficacious therapeutics. The tau protein modulates cytoskeletal structure in neurons, and thereby plays an integral role in proper development and function of the central nervous system, but its function is altered by its phosphorylation state, such that increased phosphorylation reduces tau protein function. The tau protein …


Novel Spoxazomicins Derived From Streptomyces Sp. Rm-14−6 Attenuate Ethanol Induced Cytotoxicity In Vitro, Meredith A. Saunders Jan 2016

Novel Spoxazomicins Derived From Streptomyces Sp. Rm-14−6 Attenuate Ethanol Induced Cytotoxicity In Vitro, Meredith A. Saunders

An estimated 13.9% of Americans currently meet criteria for an alcohol use disorder. Ultimately, chronic alcohol use may result in neurological deficits, with up to 85% of alcoholics exhibiting signs of cognitive decline. However, biochemical and behavioral factors contributing to this decline have remained elusive. Our ongoing research program encompasses a multi-tiered screening of a natural product library and validation process to provide novel information about mechanisms underlying these deficits and to identify novel chemical scaffolds to be exploited in the development of pharmacological treatments for alcohol use disorders in a rodent organotypic hippocampal slice culture mode. Experiment 1 sought …


The Mesocorticolimbic Dopamine Pathway Reconstituted In Vitro: Glutamate Receptors And Corticosteroid-Methamphetamine Neurotoxicity, Jennifer N. Berry Jan 2013

The Mesocorticolimbic Dopamine Pathway Reconstituted In Vitro: Glutamate Receptors And Corticosteroid-Methamphetamine Neurotoxicity, Jennifer N. Berry

Stress promotes the use of methamphetamine and other recreational substances and is often implicated in relapse to stimulant use. Thus, it is of critical importance to examine the consequences of the co-occurance of stress and methamphetamine use. Activity of the glutamatergic N-methyl D-aspartate (NMDA) receptor system appears to be involved in the neurotoxic effects of both chronic stress and methamphetamine exposure. The current studies investigated the hypothesis that chronic pre-exposure to the stress hormone corticosterone (CORT) results in an increase of NMDA receptor activity and that this will potentiate the neurotoxic effects of methamphetamine (METH). Co-cultures of the …
