background: pinopodes are suggested as biological markers of uterine receptivity, but their molecular components are unknown. objective: co-expression of galectin-3 and ?v?3 integrin at human pinopodes has been examined in this study to propose a role for them during adhesion phase of embryo implantation. materials and methods: biopsies were obtained from early and mid luteal phase endometrium ...

BACKGROUND AND OBJECTIVE The junctional epithelium attaches to the enamel surface with hemidesmosomes (of which laminin-5 and integrin-alpha(6)beta(4) are the main components) in the internal basal lamina. Laminin-5 is also involved in cell motility with integrin-alpha(3)beta(1), although their functions have not yet been clarified.The purpose of this study was to determine the functions of tho...

In multiple myeloma, malignant plasma cells are localized in marrow and rarely circulate in peripheral blood. To investigate the role of adhesion proteins in this process, we determined the expression and function of adhesion molecules on cell lines derived from patients with myeloma. The U266, ARH-77, IM-9, and HS-Sultan cell lines strongly expressed beta 1 and alpha 4 integrins (89% to 98% po...

Head and neck cancer is a capricious disease that varies greatly in its clinical behavior. The development of biomarkers that can distinguish between biologically aggressive and indolent tumors has been a long term goal of our laboratories. Predictive markers applicable to biopsy specimens should facilitate clinical management through early identification of patients at greatest risk for early ...

PURPOSE During the increased eye growth that results in myopia, the sclera undergoes biochemical and biomechanical remodeling. The cell surface integrin receptor family has important roles during tissue remodeling, regulating the extracellular matrix environment and cellular biomechanical properties. As integrin receptors may have a role in remodeling during myopia, this study detailed subunit ...

We have examined integrin expression during the remodeling of the epidermis that takes place during wound healing, using a suction blister model in which the epidermis is detached from the dermis, leaving the basement membrane intact. By immunofluorescence microscopy, we found that the same integrin subunits were expressed during wound healing as in normal epidermis with very little change in t...

In a previous prospective study of 80 patients with squamous cell carcinoma of the upper aerodigestive tract, a progressive increase in expression of the integrin cell adhesion molecule alpha 6 beta 4 in suprabasilar cell layers of the tumor parenchyma was associated with an increase in early recurrence after therapy. In this study, we determined the relationship of the altered expression patte...
