探花直播first ever basic training package to teach students and scientists how to best use the fruit fly, Drosophila, for research has been published. It鈥檚 hoped it will encourage more researchers working on a range of conditions from cancer to Alzheimer鈥檚 disease to use the humble fly.
探花直播unique scheme has been put together by Dr Andreas Prokop from the Faculty of Life Sciences at the 探花直播 of Manchester and John Roote from the Department of Genetics at the 探花直播 of Cambridge.
John Roote said, 鈥淚n 1910 Thomas Hunt Morgan isolated the first Drosophila sex-linked mutation, white.听 Since then many thousands of research workers have realised the potential of the humble fruit fly.
鈥 探花直播powerful research tools that we have today combined with a century of background knowledge, the vast collections of stocks that are available to everyone and the fortuitous 鈥榩re-adaptation鈥 of the fly for life in a laboratory ensure that Drosophila melanogaster maintains its position as the pre-eminent model organism for research in genetics.听 However, until now a comprehensive teaching programme to guide students through the often daunting first few steps has been surprisingly absent.鈥
Dr Prokop said: 鈥淧eople don鈥檛 realise just how useful the tiny fruit fly can be when it comes to research. Fellow scientists are often not aware of their genetic value for research. For example, about 75% of known human disease genes have a recognisable match in the genome of fruit flies which means they can be used to study the fundamental biology behind complex conditions such as epilepsy or neurodegeneration.鈥
Fruit flies have been used for scientific research for more than a hundred years. They have allowed scientific breakthroughs in genetics, body structure and function. 探花直播first jet lag gene and the first learning gene were identified in flies as well as breakthroughs in neuroscience, such as the discovery of the first channel proteins.
Dr Prokop says: 鈥淔lies need very little space so are ideal for breeding. They develop in just two weeks and it is a simple process to follow a genetic mutation through the generations by analysing the patterns on their bristles, wings or eyes which provide easy visible markers.鈥
Despite the flies鈥 contribution to scientific research through the ages, including four Nobel prizes, there is a concern that fewer scientists are aware of their potential. Part of the reason for this has been a trend away from basic genetics training in schools and universities which makes it harder for newcomers to the fly.
Together with John Roote, the manager of the main Cambridge fly facility, Dr Prokop has developed a four part training package for all scientists.听 It includes a self-study introductory manual, a short practical session on gender and marker selection, an interactive Powerpoint presentation and finally an independent training exercise in mating scheme design.
Dr Prokop says it鈥檚 a well rounded package: 鈥淲e wanted to make sure that key aspects of fly research become apparent to the newcomer right away, such as a basic appreciation of why Drosophila is used for research, the nature of the fly stocks we use, an understanding of classical genetic rules and the knowledge of the nature and use of classical genetic markers but also the use of modern transgenic technologies.鈥
He continues: 鈥淲e鈥檝e had a really good response from people who鈥檝e tested the training package and we鈥檙e confident this will encourage more scientists to consider using the fruit fly in the future.鈥
