Genetic analysis of Drosophila melanogaster chromosome 3 neurodegenerative mutants induced with ethyl methanesulfonate

Neurodegeneration, a pathological state accompanied by brain neuronal necrosis and changes in behavior, has been described for many animal species. However, the genetic control and molecular mechanisms of this process are yet vague. A large collection of neurodegenerative mutants of a model object, Drosophila melanogaster, can enhance understanding of these mechanisms. In this work, we have demonstrated that genetically determined anatomical changes in Drosophila brain are accompanied by a decreased lifespan and deviations from the wild-type sexual behavior and locomotor activity. It has been found that the genes vacuous and loechrig are candidates for molecular genetic analysis in eight mutants from the collection.
