Abstract
O-glycans are the cell-surface carbohydrates attached to membrane proteins through serine (Ser) or threonine (Thr). Recently, extensive investigation on O-glycans in cancer cells has revealed that there is a certain type of O-glycan that can promote cancer cell metastasis. Cancer cells expressing the O-glycans called core2 O-glycans exhibit a high ability to evade host tumor rejection systems by natural killer (NK) cells. Evasion from the NK tumor rejection systems by using core2 O-glycans facilitates the cancer cells to survive longer in host circulation. Core2 O-glycans expressing cancer cells thus increase the chance to invade other organs, thereby resulting in the promotion of metastasis. In this chapter, it is illustrated how core2 O-glycans in cancer cells evade host immune systems to promote metastasis.
