Nature Reviews Cancer article traces possible role of damaged DNA in tumor development
Atlanta – DNA provides the instruction manual for all life forms. Occasionally, instructions are not carried out properly, and bad messages are sent leading to the creation of mutant proteins and possible tumor development.

Researchers advance understanding of enzyme that regulates DNA
CHAMPAIGN, Ill. — Thanks to a single-molecule imaging technique developed by a University of Illinois professor, researchers have revealed the mechanisms of an important DNA-regulating enzyme.
Helicase enzymes are best known for “unzipping…
New drug could help target cancer cells with deadly accuracy
Researchers in Britain have developed a drug they say could revolutionize the effectiveness of radiation on cancer. Radiotherapy is used to destroy cancer cells by zapping their DNA, thus disrupting their ability to function and reproduce. But like other cells in the body, cancer cells have a sort of DNA repair kit that can minimize these effects. The new drug disables the DNA repair process and allows radiotherapy to target tumors with “deadly accuracy.”
