Aberrant N-glycolylneuraminic acid in breast MCF-7 cancer cells and cancer stem cells

open access: yesFrontiers in Molecular Biosciences, 2022
N-Glycolylneuraminic acid (Neu5Gc) is not normally detected in humans because humans lack the hydroxylase enzyme that converts cytidine-5′-monophosphate-N-acetylneuraminic acid (CMP-Neu5Ac) to CMP-Neu5Gc; thus, any Neu5Gc appearing in the human body is ...
