In this regard, a correlation has been found by flow cytometry between functional α-DG glycosylation (i.e., matriglycan levels) and E-cadherin expression (or simultaneous lack of both molecular properties) in several established cell lines derived from a variety of human tumor types, including colon, prostate, renal and breast cancers, as well as epidermoid carcinoma, although this was not always the case [103]. This evidence concerns the gene CDH1 and breast cancer.
