摘要
The cell polarity regulator Crumbs3 (Crb3) promotes colon cancer cell migration and metastasis. However, the underlying mechanism of cancer cell migration regulated by Crb3 has not been fully elucidated. Here, we demonstrated that Crb3 is associated with cell migration by regulating glycosphingolipid (GSL) expression in human colon cancer cells. Crb3-knockout (KO) cells showed a remarkable increase in ganglioside GM3 (GM3) on the cell surface. Reduced migration by Crb3-KO cells was restored by forced expression of both Crb3 and Neuraminidase3 (Neu3). Immunofluorescent staining revealed that most Crb3 is colocalized with the recycling endosome marker Rab11. These findings show that Crb3 may promote colon cancer cell migration by regulating the expression of GSLs on the cell surface.
