\n\t\t\t\t\t<\/div><\/div><\/div>\n\t\t\tGiven that the vast majority of genes in Drosophila are conserved in mice and humans, the results obtained may also lead researchers to perform similar studies in more clinically relevant models. Proceedings of the National Academy of Sciences USA (PNAS) has published the study online this week.<\/p>\n
Argentinian scientist Andr\u00e9s Dekanty, a Juan de la Cierva researcher in the Mil\u00e1n lab and first author of the article, explains that “for the first time we have a genetic model that allows us to understand the events that take place, starting from when cells begin to accumulate genomic errors until the development of a tumour.” <\/p>\n
The Mil\u00e1n team began by provoking genomic instability in a selection of cells in the fly wing. They then prevented these cells, with an aberrant number of chromosomes (aneuploidy), from succumbing to the cells’ natural defense mechanisms so that they would survive. From there, they observed that the cells spread throughout the tissue, became mobile, activated the growth of adjacent cells, and degraded the basal membrane that kept them in place, allowing them to break free and even invade nearby tissues. <\/p>\n
“All of these events are things that we see in cancer. This fly model will therefore help us to identify each of the genes and molecules involved in epithelial cell detachment (delamination), motility, abnormal growth, basal cell degradation and invasion,” says Mil\u00e1n. <\/p>\n
“This study takes things one step beyond, however,” say the researchers, “and opens a fundamental conceptual debate.” This is the first time that these phenomena have been described in relation to genomic instability. “This has allowed us to propose something that hasn’t yet been possible to study in depth and that now should be taken into serious consideration. Is genomic instability the cause of tumorigenesis?” says Mil\u00e1n. <\/p>\n
