Drosophila research has been and continues to be an essential tool for many aspects of biological scientific research and has provided insight into numerous genetic, biochemical, and behavioral processes. As well, due to the remarkable conservation of gene function between Drosophila and humans, and the easy ability to manipulate these genes in a whole organism, Drosophila research has proven critical...
Antifolates, such as methotrexate, are used to inhibit dihydrofolate reductase (DHFR), an enzyme essential for the biosynthesis of thymidylate, purines, and several amino acids. DHFR sequences corresponding to mutations found in a methotrexate resistant Drosophila S3 cell line (L30Q), a methotrexate resistant fly population (K31P, Q134K), as well as predicted in silico (L22R) were expressed in Chinese...
