Another rather recent finding in the field of glycosylation came from phyllodes tumors of the breast, an aggressively growing type of breast cancer: the gene expression of Axl and ST6GalNAcII was increased in malignant tumors, whereas the expression of Axl seems to be dependent on the expression of ST6GalNAcII. This evidence concerns the gene ST6GALNAC2 and breast carcinoma.
