Localization Of Ctg-Repeat-Containing Transgenes In Drosophila Melanogaster Myotonic Dystrophy Models, Andrea Waltrip Apr 2023

Localization Of Ctg-Repeat-Containing Transgenes In Drosophila Melanogaster Myotonic Dystrophy Models, Andrea Waltrip

Student Research Submissions

Myotonic Dystrophy Type 1, DM1, is a multi-systemic muscle wasting disorder that results from expression of expanded CTG repeats in the DMPK gene in humans. Three transgenic Drosophila melanogaster lines have been created containing 60, 250, or 480 CTG repeats to model DM1. The transgenic repeats are expressed using the GAL4/UAS system. Expression of long-repeat transgenes ((CTG)250 and i(CTG)480) produces phenotypes consistent with DM1, relative to control lines ((CTG)60). The precise chromosomal location of insertion of the transgenes has not been reported. We used classical genetic approaches to localize CTG-repeat transgene insertion to a specific …


Identifying Genes Downstream Of Mef2 That Influence Ethanol Sedation In Drosophila Melanogaster, Ananya Talikoti Jan 2021

Identifying Genes Downstream Of Mef2 That Influence Ethanol Sedation In Drosophila Melanogaster, Ananya Talikoti

Theses and Dissertations

Alcohol use disorder is a global public health issue that affects millions across the world. It can result in negative physical and mental health outcomes, and currently treatment options are limited and rates of relapse are high. Identifying genes that affect aspects of ethanol behaviors in model organisms, such as Drosophila melanogaster, can serve to eventually develop more robust therapeutic interventions for those experiencing alcohol dependence. Previous studies have identified a relationship between a person's initial sensitivity to alcohol and their abuse potential for the drug in later life. Therefore, we can study sedation behaviors in Drosophila melanogaster to …
