Abstract

Aberrant expression of certain glycosphingolipids (GSLs) is associated withthe differentiation of acute myeloid leukemia (AML) cells. However, the expressionpatterns of GSLs in AML are still poorly explored because of their complexity, the presenceof multiple isomeric structures, and tedious analytical procedures. In this study, weperformed an in-depth GSL glycan analysis of 19 AML cell lines using porous graphitizedcarbon liquid chromatography-mass spectrometry revealing strikingly different GSL glycanprofiles between the various AML cell lines. The cell lines of the M6 subtype showed a highexpression of gangliosides with alpha 2,3-sialylation and Neu5Gc, while the M2 and M5subtypes were characterized by high expression of (neo)lacto-series glycans and Lewis A/Xantigens. Integrated analysis of glycomics and available transcriptomics data revealed theassociation of GSL glycan abundances with the transcriptomics expression of certainglycosyltransferases (GTs) and transcription factors (TFs). In addition, correlations werefound between specific GTs and TFs. Our data reveal TFsGATA2,GATA1, andRUNX1as candidate inducers of the expression of gangliosides and sialylation via regulation of the GTsST3GAL2andST8SIA1.Inconclusion, we show that GSL glycan expression levels are associated with hematopoietic AML classifications and TF and GT geneexpression. Further research is needed to dissect the regulation of GSL expression and its role in hematopoiesis and associated malignancies
