NEW YORK (Reuters Health) - Stanford researchers have discovered the normal function of the BRCA1 gene, the gene that--when mutated--leads to a high risk of breast cancer. According to the new study, the BRCA1 gene normally has the job of finding and repairing damaged DNA.
To test their theory that BRCA1 helps to repair damaged DNA, the researchers tweaked cells to make them overproduce the BRCA1 gene, according to the study, which was published in the advance online edition of Nature Genetics.
