The ether lipid 1-O-octadecyl-2-O-methyl-3-glycero-phosphocholine (ET-18-OMe) inhibits cell-cell adhesion and induces invasiveness of breast cancer cells. Previously, we showed that a loss of cell-cell adhesion was due to sterical hindrance of E-cadherin by the anti-adhesive properties of the cell surface mucin episialin. Here, we demonstrated that the ether lipid ET-18-OMe induced the translocation of E-cadherin and episialin to membrane microdomains, enriched in glycosphingolipids, known to be involved in cell-cell adhesion and cell signaling. In addition, it was found that E-cadherin and clusters of episialin colocalized and associated with the glycosphingolipid, MSGb5, upon treatment with ET-18-OMe. Together, these results suggest that ET-18-OMe inhibits cell-cell adhesion by inducing the translocation of E-cadherin and episialin into MSGb5-enriched membrane microdomains, which leads to clustering and colocalization of the pro-adhesive E-cadherin and the anti-adhesive episialin thereby inhibiting cell-cell adhesion.
