In addition, the differentially and stably expressed glycoforms in GMALT823 cells suggest that the HexNAc(2)Hex(6) glycoform on the 221N site of the CTSL protein or/and the HexNAc(2)Hex(9) glycoform on the 69N site of the LGALS3 protein are absent in host cells in MALT lymphoma, in contrast, the HexNAc(2) glycoform at the 497T site of the PDIA4 protein and/or the HexNAc(1) glycoform at the 71S site of HNRNPA2B1 are detected only in MALT lymphoma. This evidence concerns the gene LGALS3 and MALT lymphoma.
