Hallmarks of Cancer 7: Genome Instability and Mutation

BRCA1 structure

All cancers share ten underlying principles, also known as the Hallmarks of Cancer. You can read about the first six here. The seventh is defined as genome instability and mutation. Cancer Cells Evolve Not all cancer cells are equal. They vary, they compete, and the fittest survive to pass on their genes to daughter cells, [...]

Significant faults in “longevity genes” study surface

A team of Boston University scientists reported last week that they had identified a large number of gene variants that were associated with exceptional longevity. Since that story grabbed headlines, however, some skeptics have voiced concerns about the data and the study’s conclusions. Newsweek reported Wednesday that the concern over the data stems from one [...]

Some 20 percent of the human genome is already patented. But a court ruled yesterday that one company does not have the rights to some of its patents on two genes, BRCA1 and BRCA2, commonly tested for mutations to determine risk for developing breast and ovarian cancers. The decision [pdf], made March 29 by United [...]
