The Role Of Histone Demethylases In Learning And Memory In The Mushroom Body Of Drosophila Melanogaster, Crystal Keung
Electronic Thesis and Dissertation Repository
Intellectual disability (ID) is a neurodevelopmental disorder associated with many epigenetic regulators and chromatin modifying enzymes like histone lysine methyltransferases (KMTs) and demethylases (KDMs). Here, I systematically investigate the role of 7 KDMs: Su(var)3-3, KDM2, Lid, CG2982, UTX, KDM4B, JHDM2, and 1 KMT: trr in the context of learning and memory using Drosophila melanogaster. Genetic knockdown of each gene in the mushroom body (MB) of flies are tested for short- and long-term memory impairment using courtship conditioning. Knockdown of 6 KDMs and trr resulted in memory loss. MB morphology was analyzed to determine potential cause of memory loss. …

Alzheimer’s disease (AD) is a neurodegenerative disease characterized by the progressive deterioration of memory and other intellectual abilities. Accumulation of amyloid-β (Aβ) peptide, the major contributor to the senile plaques central to AD, is thought to mediate neurotoxicity by inducing oxidative stress and calcium dysregulation. Transient Receptor Potential Melastatin type 2 (TRPM2) is a calcium permeable, non-selective cation channel activated under oxidative stress and ultimately induces cell death. The APPSWE/PSEN1ΔE9 double transgenic mouse model carries the human APPswe (Swedish mutations K594N/M595L) and PS1 mutations with a deletion in exon 9 (PS1-dE9), and is one of the most commonly used AD …
