چکیده

Gicerin is a cell adhesion molecule in the immunoglobulin superfamily. This molecule has homophilic and heterophilic adhesive activities, binding to the neurite out-growth factor (NOF). We have previously reported that gicerin plays an important role in the development and regeneration as well as in the metastasis of tumors through its adhesive activities, mediating cell-cell and/or cell-extracellular matrix interactions. In this study, we investigated the involvement of gicerin in a dermal autograft chicken model. Gicerin and NOF were transiently present in the regenerating epithelia after the dermal graft transplantation. The treatment with an anti-gicerin polyclonal antibody, by placing drops onto the wounds, inhibited the adhesiveness of the grafts to the marginal skin. The chimeric protein of gicerin-IgG, gicerin-Fc, and NOF proteins promoted the regeneration of the grafts. These findings suggest the potential function of gicerin in dermal autografts, and gicerin and NOF proteins could help clinical improvement after transplantations.

Involvement of gicerin, a cell adhesion molecule, in the portal metastasis of rat colorectal adenocarcinoma cells.

Gicerin, an Ig-superfamily cell adhesion molecule, has homophilic adhesion activity, thus leading to the formation of gicerin aggregates. Gicerin is highly expressed in various embryonic tissues, and it contributes to development through its adhesive activities. In contrast, the expression of the protein is limited to the muscular tissues and endothelial cells in the mature animals. In the live...

The role of gicerin, a novel cell adhesion molecule, in development, regeneration and neoplasia.

Neurite outgrowth factor (NOF) is an extracellular matrix (ECM) protein in the laminin family and its ligand, gicerin, is a novel cell adhesion molecule in the immunoglobulin superfamily. Gicerin has a homophilic adhesive activity as well as a heterotypic manner to NOF. In the nervous systems, gicerin is expressed during developmental stage when neurons migrate or extend neurites to form a neur...

Involvement of Gicerin, a Cell Adhesion Molecule, in the Hematogenous Metastatic Activities of a Melanoma Cell Line

Gicerin is an immunoglobulin superfamily cell adhesion molecule that plays a role in development via its cell adhesive activities. After maturation, the gicerin expressionalmost disappears in most organs, except for the muscle and endothelial cells. Interestingly, various neoplastic cells strongly express gicerin in their cell membranes, indicating a potential function of gicerin in the develop...

HEMCAM, an adhesion molecule expressed by c-kit+ hemopoietic progenitors

We have characterized the adhesion molecule HEMCAM, which is expressed by hemopoietic progenitors of embryonic bone marrow. HEMCAM belongs to the immunoglobulin superfamily and consists of the V-V-C2-C2-C2 Ig domains. There are three mRNA splice variants. One has a short cytoplasmic tail; another has a long tail; while the third seems to lack transmembrane and cytoplasmic regions. Except for th...
