Summer 2012: Characterization of Drosophila Interacting Genes: Elucidating the Mechanism(s) of PolyQ Toxicity in Huntington’s Disease
By Daniel R. Camacho, Ping Zhang, Ph.D.
Polyglutamine expansions are a type of genetic mutation that is responsible for several human neurodegenerative diseases, including Huntington’s disease. The pathology of these diseases involves the accumulation of proteins containing polyglutamine domains within neuronal cells, which ultimately leads to cell death. The mechanism of toxicity of these protein aggregates is currently being investigated. My work involved using the model genetic organism Drosophila melanogaster to try to elucidate aspects of polyglutamine toxicity. Continue reading
