Abstract
ABSTRACT Somatic recombination is essential to protect genomes of somatic cells from DNA damage but it also has important clinical implications, as it is a driving force of tumorigenesis leading to inactivation of tumor suppressor genes. Despite this importance, our knowledge about somatic recombination in adult tissues remains very limited. Our recent work, using the Drosophila adult midgut has demonstrated that spontaneous events of mitotic recombination accumulate in aging adult intestinal stem cells and result in frequent loss of heterozygosity (LOH). In this Extra View article, we provide further data supporting long-track chromosome LOH and discuss potential mechanisms involved in the process. In addition, we further discuss relevant questions surrounding somatic recombination and how the mechanisms and factors influencing somatic recombination in adult tissues can be explored using the Drosophila midgut model.
期刊介绍：
Fly is the first international peer-reviewed journal to focus on Drosophila research. Fly covers a broad range of biological sub-disciplines, ranging from developmental biology and organogenesis to sensory neurobiology, circadian rhythm and learning and memory, to sex determination, evolutionary biology and speciation. We strive to become the “to go” resource for every researcher working with Drosophila by providing a forum where the specific interests of the Drosophila community can be discussed. With the advance of molecular technologies that enable researchers to manipulate genes and their functions in many other organisms, Fly is now also publishing papers that use other insect model systems used to investigate important biological questions.
Fly offers a variety of papers, including Original Research Articles, Methods and Technical Advances, Brief Communications, Reviews and Meeting Reports. In addition, Fly also features two unconventional types of contributions, Counterpoints and Extra View articles. Counterpoints are opinion pieces that critically discuss controversial papers questioning current paradigms, whether justified or not. Extra View articles, which generally are solicited by Fly editors, provide authors of important forthcoming papers published elsewhere an opportunity to expand on their original findings and discuss the broader impact of their discovery. Extra View authors are strongly encouraged to complement their published observations with additional data not included in the original paper or acquired subsequently.
