Scientists have found that cancers in the pancreas (left) readily metastasize because these tumors suppress levels of an enzyme, MSRA, that pulls oxygen atoms off amino acids called methionine. As MSRA levels decrease, methionines on proteins become more oxidized. This causes one...Read more about Scientists find trigger that sets off metastasis in pancreatic cancer
