McGill researchers shed light on formation of carcinogen in food

...ed dangerous. Although furans have been linked to cancer in experimental animals, there is no direct evidence that furans are human carcinogens. "Even so," says Dr. Yaylayan, "food companies and government agencies are keeping a close eye on the situation. It's important to know exactly what chemicals are...

Key mechanism in genetic inheritance during cell division identified

...hromosome segregation during mitosis contribute to cancer and birth defects. From various genetic experiments we know that the activity of a 10-protein complex of kinetochores, called Dam1, is responsible for the faithful segregation of chromosomes during mitosis. While we don't know at this time that ring ...

Light therapy may combat fungal infections, new evidence suggests

...th HIV/AIDS, and patients treated with steroids or cancer chemotherapy. The fungus' global importance as a health threat has therefore risen in parallel with the increase in immunosuppressive therapies and the worldwide HIV/AIDS epidemic. Light normally inhibits mating of C. neoformans. The Duke team has n...

Computational Method Speeds Mapping of Cell Signaling Networks

Newly discovered pathway might help in design of cancer drugs

... work: They kill off tumors by linking up with the cancer cells' DNA and sticking its genetic code together so it dies. Our discovery takes that a step further, establishing that there is a way to efficiently create this type of damage by modifying the DNA itself." In the lab, Greenberg and his team used o...
