Osteopontin also known as bone sialoprotein (BSP). Osteopontin role as a linking protein. it is an extracellular structural protein and therefore an organic component of bone. Osteoprontin (OPN) binds to several integrin receptors containing α4β1, α9β1, and α9β4 expressed by leukocytes. These receptors have been well-stable to function in cell adhesion, migratio...
background: the ovariectomized animals are good models to evaluate the effect of different steroid hormone treatments on implantation events and the pattern of integrin expression. therefore, this study was performed to compare the expression of integrins and osteopontin (opn) in correlation with pinopode development in ovariectomized mice endometrium which was subjected to steroid hormones. me...
Background and Aim: Fibrous dysplasia (FD) and ossifying fibroma (OF) are the most important fibro-osseous lesions (FOLs) of the jaws with similarities in radiographic and morphological features while showing completely different biological behavior. Limited studies have been evaluated immunohistochemistry markers, such as osteopontin (OPN) and osteocalcin to help differentiate these two lesion...
Osteopontin (OPN) is a non-collagenous, glycosylated phosphoprotein associated with biomineralization in osseous tissues, as well as ectopic calcification. We previously reported that osteopontin was co-localized with calcified deposits in atherosclerotic lesions, and that osteopontin potently inhibits calcium deposition in a human smooth muscle cell (HSMC) culture model of vascular calcificati...
PURPOSE Osteopontin is a cytokine found in many tissues and plays a role in tissue injury and repair. This study had two goals: to characterize osteopontin expression after status epilepticus (SE), and to test the hypotheses that osteopontin affects the susceptibility to seizures or alters cell death and inflammation after SE. METHODS Pilocarpine was used to induce SE in OPN(-/-) and OPN(+/+)...
Objective Osteopontin (Opn) is one of the co-factors which participates in cell adhesion and invasion during implantation process. Increased incidence of spontaneous abortion is reported in diabetic women. Several reports have shown Opn gene expression changes in diabetic condition in several tissues. Therefore, this study was designed to evaluate the effects of diabetes on Opn gene expression ...
OBJECTIVES Osteopontin (OPN) is upregulated in left ventricular hypertrophy and is stimulated by angiotensin II (AngII). Our objective was to determine whether mice deficient in OPN would be protected from AngII-induced cardiac fibrosis. BACKGROUND Interstitial fibrosis can lead to myocardial dysfunction and ultimately heart failure. Osteopontin activates integrins that regulate cell adhesion...
BACKGROUND The metastasis gene osteopontin (OPN) is subject to alternative splicing, which yields three messages, osteopontin-a, osteopontin-b and osteopontin-c. Osteopontin-c is selectively expressed in invasive, but not in noninvasive tumors. In the present study, we examined the expression of OPN-c in esophageal squamous cell carcinomas (ESCCs) and assessed its value as a diagnostic biomarke...
Osteopontin (OPN), a secreted phosphoprotein, has been implicated in various biological phenomena (e.g. bone development, sepsis, tumor progression, and metastasis). Its role in any context is poorly understood. OPN contains a conserved Gly-Arg-Gly-Asp-Ser (GRGDS) sequence, and binds to cells via integrin-mediated mechanisms. Using recombinant human osteopontin-glutathione S-transferase fusion ...
