Phytohemagglutinin-L (PHA-L) lectin surface binding of N-linked beta 1-6 carbohydrate and its relationship to activated mutant ras in human pancreatic cancer cell lines.

Abstract excerpt

Alterations of the N-linked carbohydrate core structure of cell surface glycoproteins (beta 1-6 branching) can be detected by phytohemagglutinin (PHA-L) lectin binding and has been linked to tumor progression and K-ras activation in colon cancer. The purpose of this study was to determine the prevalence of this carbohydrate alteration and its relationship to K-ras activation in pancreatic cancer. Nine human...
