Chromosomal 'Breakpoints' Linked to Canine Cancer
Reference- http://www.sciencedaily.com/releases/2011/11/111103132359.htm
Summary- When new species evolve they leave genetic evidence behind in the form of breakpoint regions. These regions are sites on the genome where chromosomal broke during speciation’s. NC state and a graduate student Shannon Becker looked at the breakpoint regions that occurred when canid species were different during evolution. They compared the genomes of several wild canine species with those of domestic dogs. By overlaying the genomes they found a shared breakpoint among 11 different canid species evolution breakpoint. The place where the canid chromosome is that they are in the same region associated with chromosome which spontaneously occurring cancer. It would be a new tool in cancer detection and treatment.
Critique- Even though they found that the region area with the canid chromosome occurred cancer how would it really be able to use to treat cancer.
Impact- If they find more information about this they can use new tools in cancer detection and treatment. That would help especially in treatment for cancer.
