WebFeb 24, 2016 · Activation of an aberrant glycosylation pathway in cancer cells can lead to expression of the onco-foetal sialyl-Tn (sTn) antigen. STn is a truncated O-glycan containing a sialic acid α-2,6 linked to GalNAc α-O-Ser/Thr and is associated with an adverse outcome and poor prognosis in cancer patients.The biosynthesis of the sTn antigen has been … WebGlycosylation is an important post-translational modification, giving rise to a diverse and abundant repertoire of glycans on the cell surface, collectively known as the glycome. ...

Leukocytes move through the blood stream and then tether themselves to the endothelial wall and roll along the endothelial tissue to determine if they want to leave the bloodstream to get to necessary tissue. Sialyl-Lewis is a necessary partner for the three selectins that bind the leukocyte and endothelial cells. When sialyl-Lewis is part of an O-glycan and attached to CD34 it can then bind to L-selectin. For the binding t… developing a contract management plan
