A metabolic treatment for pancreatic cancer?

nitrogen disposal is important to pancreatic cancer
Targeting an enzyme that helps dispose of excess nitrogen curbed malignant growth of pancreatic tumors in obese mice.

Pancreatic cancer has become the third leading cause of cancer mortality. Its incidence is rising in parallel with the rise in obesity, and it’s hard to treat: five-year survival still hovers at just 8 to 9 percent. A new study published online in Nature Communications finds early success with a completely new, metabolic approach: reducing tumors’ ability to get rid of excess nitrogen.

The researchers, led by Nada Kalaany, PhD, of Boston Children’s Hospital’s Division of Endocrinology and the Broad Institute of MIT and Harvard, provide evidence that targeting the enzyme arginase 2 (ARG2) can curb pancreatic tumor growth, especially in people who are obese.

“We found that highly malignant pancreatic tumors are very dependent on the nitrogen metabolism pathway,” says Kalaany.
