Research suggests new avenue for stopping, preventing colon cancer
...PPARdelta, plays an important role in development, wound
healing and fat metabolism. In the current issue of the journal Cancer Cell, the scientists reported that they could inhibit polyp development in mice by "knocking out" the PPARdelta gene. PPAR stands for peroxisome proliferator-activated receptor, a...
Bone marrow cells routinely help with wound healing

UCSD researchers are first to demonstrate molecular link between inflammation and cancer
...researcher compared the inflammatory response to a wound
healing response, saying tumors were wounds that do not heal. Even without proof of the inflammation-cancer link, cancer therapies have been developed that utilize non-steroidal anti-inflammatory drugs (NSAIDs) to inhibit NF-kB and other mediators o...
