In the present study, we showed that AML and CML differ in glycosylation catalyzed by ALG8 alpha-1,3-glucosyltransferase (ALG8), carbohydrate sulfotransferase 14 (CHST14), exostosin glycosyltransferase 2 (EXT2), protein O-linked mannose N-acetylglucosaminyltransferase 1 (beta 1,2-) (POMGNT1), protein O-mannosyltransferase 2 (POMT2) and transmembrane protein 258 (TMEM258) and 59 (TMEM59). Here, EXT2 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
