Latest DNA repair Stories
For several decades, researchers have been linking genetic mutations to diseases ranging from cancer to developmental abnormalities.
Scientists from A*STARâ€™s Institute of Medical Biology (IMB) in Singapore and the University of Hong Kongâ€™s Department of Medicine have produced the world's first human cell model of progeria, a disease resulting in severe premature ageing in one in four to eight million children worldwide.
UNC scientists who study how cells repair damage from environmental factors like sunlight and cigarette smoke have discovered how a "chaperone" enzyme plays a key role in cells' ability to tolerate the DNA damage that leads to cancer and other diseases.
Remarkable new research overthrows the conventional view that cancer always develops in a steady, stepwise progression.
Most of the time cancer seems to creep up gradually over time; cells become premalignant, then increasingly abnormal before they become cancerous.
Scientists have discovered how a network of repair proteins enables bacteria to prioritise the repair of the most heavily used regions of the DNA molecules that carry the instructions necessary for living cells to function.
The sun's ultraviolet light activates an enzyme that helps skin cancer cells survive and proliferate, researchers report.
Breast cancers that arise sporadically, rather than through inheritance of certain genes, likely start with defects of DNA repair mechanisms that allow environmentally triggered mutations to accumulate.
A new drug that targets proteins responsible for helping cancer cells to repair damage to their DNA has shown promising anti-tumour activity in its first trial in humans.
