WebHigh sialic acid content of the cancer glycocalyx has been implicated in both decreased anti-tumor activity and poorer survival outcomes (Brossart et al., 2001). Perhaps most critically, the increased sialic acid content in tumor cells increases the amount of ligands for self-inhibitory siglecs on the immune cell surface (Crocker et al., 2007). WebThe most common sialic acids are N-acetylneuraminic acid (Neu5Ac, NeuNAc or NANA), N -glycolylneuraminic acid (Neu5Glc), and N -acetyl-9- O -acetylneuraminic acid (Neu5,9Ac 2 ). 1 Substitutions may be made at carbons C4, C7, C8, and C9 and the amine located at C5, and multiple substitutions contribute to the variety of possible structures.
