Backbone assignment of osteopontin, a cytokine and cell attachment protein implicated in tumorigenesis.

چکیده
OPN is an RGD-containing protein overexpressed in cells transformed by v-myc and v-mil(raf) oncogenes. Here we report the resonance assignment of recombinant quail OPN and provide NMR evidence that quail OPN is an intrinsically unstructured protein in solution.

P 118: Osteopontin: An Early Player in Neuroinflammation Disease
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...
متن کاملThe influence of osteopontin on the pathogenesis of alopecia areata and its association with disease severity
Background: Alopecia Areata (AA) is an autoimmune disease affecting hair follicles. Although many details are well specified in the pathogenesis of the disease, there exist certain aspects which require more investigations. Given the fact that the increase in Th-1 immunity is the essential part of the pathogenesis, the incrimination of osteopontin, as a Th-1 cytokine, is considered appropriate ...

Glutathione (GSH) is the most abundant low molecular weight- thiol and thus representing the first line of cellular defense against oxidative stress in biological systems. Other important functions of glutathione include regulation of gene expression, signal transduction, cell proliferation and apoptosis, cytokine production and immune response. Intracellular glutathione concentrations vary fro...
متن کاملPromotion of malignant astrocytoma cell migration by osteopontin expressed in the normal brain: differences in integrin signaling during cell adhesion to osteopontin versus vitronectin.
The extracellular matrix of the normal adult brain lacks expression of most of the adhesive glycoproteins that are known to promote cell attachment, and it has been thought that the malignant invasion of astrocytoma tumor is mediated primarily by remodeling of the matrix by the tumor cells. It has been reported, however, that normal brain neuropil does contain a protein(s) that promotes cell at...
متن کاملThe effect of resistance training and date pollen extract on bone tissue density and osteoblast cell proliferation in young male rats
Extended Abstract 1.Introduction One of the tissues that is affected by physical activity is bone. Bone is one of the tissues that needs to receive mechanical load to have normal function as a key factor in strengthening bone mass (2). Evidence shows that the mechanical load resulting from physical activity activates a set of proteins involved in the process of osteoblast activation and inhib...
