This year’s event will feature more than 240 students from colleges around the region, as well as eight University of California campuses, two dozen universities across the U.S. and several visiting international students.

Tumor Suppressor Mutations Alone Don’t Explain Deadly Cancer

Although mutations in a gene dubbed “the guardian of the genome” are widely recognized as being associated with more aggressive forms of cancer, researchers at the University of California, San Diego School of Medicine have found evidence suggesting that the deleterious health effects of the mutated gene may in large part be due to other genetic abnormalities, at least in squamous cell head and neck cancers.

Pepper and Halt: Spicy Chemical May Inhibit Gut Tumors

Researchers at the University of California, San Diego School of Medicine report that dietary capsaicin – the active ingredient in chili peppers – produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.

Birthday Matters for Wiring-Up the Brain’s Vision Centers

Researchers at the University of California, San Diego School of Medicine have evidence suggesting that neurons in the developing brains of mice are guided by a simple but elegant birth order rule that allows them to find and form their proper connections.
