ceptor known as "RAGE" which also plays a role in diabetes, arthritis and Alzheimer's disease. If RAGE is blocked in pancreatic cancer cells, addition of synthetic S100P to the tumor does not accelerate growth.

While Logsdon was defining S100P in pancreatic cancer, a Japanese research team working on allergies ran an experiment to see which proteins "stuck" to anti-allergy drugs, including cromolyn. Several members of the S100 family did. Logsdon then discovered that the drug also bound to S100P. He applied cromolyn to laboratory pancreatic cancer cells, and found that tumor growth was slowed. A larger effect was seen when the chemotherapy agent gemcitabine was combined with cromolyn.

Logsdon suspects that cromolyn may have other anti-tumor effects, a theory which he is currently testing. "For me this is pretty thrilling," he says. "In a relatively short time, we have gone all the way from discovering a molecule to preparations for a clinical trial."
