Mayo Clinic collaboration discovers protein amplifies DNA injury signals

... important start to understanding how we might one day design new treatments that help this repair system recover from injury or resist injury." Dysfunction of the DNA damage response pathway makes the gene unstable. Genomic instability is the driving force in tumor formation, which is why cancer resear...

Gene patterns in white blood cells quickly diagnose disease

...development Hammamieh and her colleagues foresee a day when hand-held devices could be used at the site of a suspected bioterrorism attack to determine who has been exposed within hours instead of days that would be required using traditional culture methods. "The technology is not there yet, but wit...

Expedition discovers marine treasures

Removing DNA repair gene causes metabolic syndrome

... that damages their DNA. Such techniques could one day become therapies. "One may be able to develop a diagnostic method to do early screening," Lloyd said. "Or there could be a drug discovery mechanism in which you enhance the transcription process (of NEIL1) and just make more. Maybe you only have one...
