Obesity is associated with a state of chronic, low-grade inflammation characterized by abnormal cytokine production and macrophage infiltration into adipose tissue, which may contribute to the development of insulin resistance. During immune responses, tissue infiltration by macrophages is dependent on the expression of osteopontin, an extracellular matrix protein and proinflammatory cytokine t...

PURPOSE S100A4 and the estrogen-inducible osteopontin are alone capable of inducing angiogenesis and metastasis in rodent models for breast cancer. The present study assesses the relationship of S100A4 and osteopontin with vessel density and estrogen receptor alpha (ERalpha) in primary tumors and with survival of patients to ascertain their involvement in metastatic breast cancer. EXPERIMENTA...

Background: Osteopontin plays a crucial role in fertilization and subsequent embryonic development. Methods: The fresh semen samples were collected from crossbred Jersey Haryana breeding bulls. proteins the seminal plasma sperm membrane precipitated analysed by SDS-PAGE followed western blotting. Based on concentration of osteopontin plasma, bulls grouped as high (≥20 pg/ml), medium (10-20 pg/m...

Small 1,000-bp fragments of genomic DNA obtained from human malignant breast cancer cell lines when transfected into a benign rat mammary cell line enhance transcription of the osteopontin gene and thereby cause the cells to metastasize in syngeneic rats. To identify the molecular events underlying this process, transient cotransfections of an osteopontin promoter-reporter construct and fragmen...

As cancer development involves pathological vessel formation, 16 angiogenesis markers were evaluated as potential ovarian cancer (OC) biomarkers. Blood samples collected from 172 patients were divided based on histopathological result: OC (n = 38), borderline ovarian tumours (n = 6), non-malignant ovarian tumours (n = 62), healthy controls (n = 50) and 16 patients were excluded. Sixteen angioge...

Alcohol consumption is a leading cause of liver disease worldwide; thus, there is an urgent need to develop novel therapeutic interventions. Key events for the onset and progression of alcoholic liver disease result in part from the gut-to-liver interaction. Osteopontin is a cytokine present at high concentration in human milk, umbilical cord, and infants' plasma with beneficial potential. We h...

Efficient regeneration of injured or dystrophic skeletal muscle relies upon the coordinated action of invading inflammatory cells that induce muscle fibre necrosis and phagocytosis (Lescaudron et al., 1999; Tidball and Wehling-Henricks, 2007), and an endogenous pool of quiescent myogenic stem cells known as satellite cells that form new muscle fibres (Zammit et al., 2006). The failure of effici...

Autoimmune uveitis is an intraocular inflammation that arises through autoreactive T-cells attacking the inner eye, eventually leading to blindness. However, the contributing molecular pathomechanisms within the affected tissues remain as yet elusive. The extracellular matrix (ECM) is a highly dynamic structure that varies tremendously and influences the encompassing tissue. In order to assess ...

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...

Previous studies have demonstrated that enalapril and verapamil seem to attenuate the cyclosporine nephrotoxicity. However, the mechanisms have not been completely understood, especially on molecular events. The aim of this study was to examine the effect of individual or combined treatment on osteopontin, TGF-beta, endothelin-1 and procollagen alpha 1(I) mRNA expressions. Enalapril (50 mg/L in...
