Unknotting DNA clue to cancer syndrome

...ken DNA, matching chromosomes associate so that an intact chromosome can act as a template for the damaged one. The DNA strands are then exchanged to form four-way structures called Holliday junctions. To complete repair, these junctions are resolved in one of two ways: either leaving the original chromosom...

Cell damage caused by brushing may help keep gums healthy

...ical forces must have been transmitted through the intact epithelium to the muscle cells, says Dr. McNeil, director of the MCG Cell Imaging Core Facility. It means our epithelium is tough and maintains a nice, resilient barrier but, not surprisingly, since its not a hard surface, it transmits forces quite r...

A friendly foe -- Bacteria residing in the gut boost immune response to tumors

This surprising result indicated that another mechanism for the efficacy of TBI also exists. They fou...

Although this organism was able to enter the gastrointestinal epithelial cells lining the gut of both Muc1-deficient and Muc1-intact mice, intestinal damage was more common in Muc1-deficient animals, and the authors determined that the preventi...
