Middle T antigen (MT) is the principal oncoprotein of murine polyomavirus. Experiments on the acute immediate effects of MT expression on cellular RNA levels showed that expression of osteopontin (OPN) was strongly induced by MT expression. Osteopontin is a protein known to be associated with cancer. It has a role in tumor progression and invasion. Protein analysis confirmed that MT induced the...
Background: Interfering with cell proliferation and survival is a critical role for antineoplastic drugs leading to cell death through induction of apoptosis. Alternative treatments with herbal extracts offer insights into acute myeloid leukemia (AML) therapy. Parthenolide (PTL), an extract from feverfew, induces apoptosis in primary human leukemia stem cells (LSCs) and bulk leukemic cell popul...
Osteopontin (OPN) is a pro-inflammatory cytokine that can be secreted from many cells including activated macrophages and T-lymphocytes. Elevated levels of osteopontin in the plasma, cerebrospinal fluid or brain of individuals with neurodegenerative diseases such as multiple sclerosis (MS), Parkinson's and Alzheimer's disease and more recently in HIV-associated neurocognitive disorder has been ...
Objective: In obesity, chronic low grade inflammation, created by induction of pro-inflammatory markers, causes adipocyte dysfunction in adipose tissue. Adipocytes dysfunction is associated with various diseases including insulin resistance and obesity. In obesity, inflammatory factors such as osteopontin (OPN), angiopoietin-like protein 2 (Angptl2) and transforming growth factor-β (TGF-β) are...
Osteopontin (OPN) is a 33.7 kDa intrinsically disordered protein and a member of the SIBLING family of proteins. OPN is bearing a signal peptide for secretion into the extracellular space, where it exerts its main physiological function, the control of calcium biomineralization. It is often involved in tumorigenic processes influencing proliferation, migration and survival, as well as the adhes...
Osteopontin (OPN) is a multifunctional glycophosphoprotein secreted by many cell types, including osteoblasts, lymphocites, macrophages, epithelial cells, and vascular smooth muscle cells. It has been implicated in many physiological and pathological processes, such as cell-mediated immunity, inflammation, cell survival, and tumor invasion and metastasis. Osteopontin has multiple emerging roles...
Osteopontin (OPN) is a secreted extracellular phosphoprotein involved in diverse biologic functions, including inflammation, cell migration, and antiapoptotic processes. Here we investigate the neuroprotective potential of OPN to reduce cell death using both in vitro and in vivo models of ischemia. We show that incubation of cortical neuron cultures with OPN protects against cell death from oxy...
AIM This study aims to evaluate plasma osteopontin (OPN) levels as a potential biomarker for hepatocellular carcinoma (HCC). BACKGROUND Osteopontin (OPN) is a secreted glycoprotein that is associated with tumorigenesis and metastasis. METHODS We measured plasma levels of OPN in 26 HCC patients, 27 patients with chronic liver diseases (CLD), and 15 healthy control individuals using a standar...
Background: Breast cancer (BC) is problem in developed and developing nations linked to a high mortality rate. Objective: In this study, we determined the relationships between osteopontin level, hormonal status, stage, BMI, age BC patients. Materials Methods: cross sectional 178 patients, ages ranged from 28 95 were randomly enrolled. Body mass index estimated. Plasma measured. Results: From t...
Osteopontin (OPN) is a glycophosphoprotein with multiple intracellular and extracellular functions. In vitro, OPN enhances migration of mouse neutrophils and macrophages. In cancer, extracellular OPN facilitates migration of cancer cells via its RGD sequence. The present study was designed to investigate whether osteopontin is responsible for neutrophil and macrophage infiltration in human canc...
