Pesticides may promote Parkinson's disease and exercise may offer protection
...s also showed that the amount of COX-2 protein was higher
in patients with Parkinson's disease than in those without the disease. "These results show that there is a relationship between the disease and the presence and amounts of this protein in the brain," says Przedborski. Of the different cell death m...
Potential new oncogene may be missing link in cancer-causing chain
...east cancer," he says. "We found the LRP6 gene had higher
than normal activity in five of the eight breast tumors we tested. So, it appears that an increase of LRP6 alone may lead to breast cancer in these cases." Next Bu and his colleagues plan to screen a larger group of breast cancer samples to see how ...
GENEPI: a tool to refine and fine-tune radiotherapy treatment for cancer
