摘要: Altered glycosylation on the surfaces or secreted proteins of tumor cells is common in pancreatic cancer and thought to promote progression, but factors leading changes carbohydrate structures are incompletely understood. We hypothesized that pro-inflammatory conditions can lead alterations cancer-associated glycans mucins produced by pancreatic-cancer cells. With use a novel antibody-glycan microarray method, we measured effects stimuli (oxidative stress treatment with cytokines IFNγ, IL-1α, TNFα) expression MUC1, MUC5AC, MUC16 multiple cell lines. Mucin was significantly affected specific lines, particularly involving terminal galactose N-acetylgalactosamine. In addition, responses lines grouped according cell-surface markers associated tumorigenicity, as bearing min...
