英文摘要
This program project examines the structure, biosynthesis, and roles of
selectin ligands in cell-cell communication. It also aims at elucidating
the roles of the selectin-carbohydrate interaction in tumor cell
metastasis. This program project is a close collaboration among
investigators whose expertise range from carbohydrate synthetic
chemistry, carbohydrate chemistry, carbohydrate biosynthesis, to cellular
and molecular biology.
The work centers around the sialyl Lex and related oligosaccharide
structures originally discovered by the participants in this grant as E-
selectin ligands. Structure and biosynthesis of E-, P- and L-selectin
ligands in human and mice will be investigated. In particular, the roles
of specific fucosyltransferase(s) in the formation of selectin ligands
and those of N-glycans presenting selectin ligands will be determined by
using knock-out mice. In addition, the structure and biosynthesis of the
oligosaccharide L-selectin ligand(s) will be elucidated by cloning an
enzyme that forms the ligand(s).
The regulation of selectin ligand biosynthesis will be investigated in
relation to subcellular localization of the enzymes involved in the
biosynthesis of selectin ligands. This program project also aims at
determining the roles of selectin-mediated adhesion in tumor cell
dissemination.
These studies will provide new information on selectin-carbohydrate
interactions and may help in the design of improved therapeutic
intervention in malignancies and other diseases.
