Lectin fluoresce also revealed that the expression of E-Cadherin and total bisecting GlcNAc-branched N-glycosylation of tumour tissues were enhanced by DHEA treatment (Supplementary Fig. 7D), and the bisecting GlcNAc-branched N-glycosylation of E-Cadherin was enhanced by DHEA treatment (Fig. 6k, Supplementary Fig. 7E). The gene discussed is CDH1; the disease is neoplasm.
