Application of temperature-sensitive mutations to oncogene studies in Drosophila.
Recessive oncogenes are genetic functions important in the regulation of tissue growth and differentiation. These genetic functions are defined on the basis of the phenotype expressed by homozygotes. Defining the role of these genes in normal developmental and physiological processes is important to the development of accurate models of the normal regulation of growth and differentiation. Drosophila can be a good system to investigate the neoplastic mechanism of oncogenes and provide a greater understanding in the developmental progression of both invertebrates and vertebrates. The lethal (2) giant larvae gene is a recessive oncogene of Drosophila and temperature sensitive mutations of this gene have been isolated. Here, the application of temperature-sensitive mutations in Drosophila oncogene studies is discussed.
