cells harbor the mutation. The three-stage approach to finding breast cancer genes may be used in other forms of cancer as well, Hahn continues. "Our study provides a framework for integrated genomic methods of oncogene discovery."...
UVa-led team uncovers important secret in gene replication
...ncy that comes from both copies being active. If tumor
suppressor genes, the ones that turn off cancer cells, reside in areas of the genome with asynchronous replication, the cancer cell can turn such genes off merely by mutating the one active copy instead of going through the trouble of separately muta...
