Differential expression of osteonectin/SPARC during human prostate cancer progression.
The precise mechanism(s) involved in invasion and metastasis of prostate cancer (CaP) is poorly understood. Osteonectin [ON (also known as SPARC or BM-40)] is an antiadhesive protein known to be involved in cell-matrix interactions, migration, and angiogenesis. In this report, we studied the expression of ON in human prostate cell lines, primary tumors, and metastatic foci of CaP. Reverse trans...
متن کاملExogenous thioredoxin reduces inflammation in autoimmune myocarditis.
Levels of reactive oxygen species (ROS) are tightly regulated in mammalian cells. A variety of enzymes produce ROS, including NAD(P)H oxidase, xanthine oxidase, glucose oxidase, myeloperoxidase, the family of nitric oxide synthases, and mitochondrial enzymes.1–4 Low levels of ROS such as superoxide or hydrogen peroxide regulate highly specific targets.5,6 In the cardiovascular system, for examp...
متن کاملSPARC/Osteonectin Induces Matrix Metalloproteinase 2 Activation in Human Breast Cancer Cell Lines1
Activation of the matrix metalloproteinase 2 (MMP-2) has been shown to play a major role in the proteolysis of extracellular matrix (ECM) associated with tumor invasion. Although the precise mechanism of this activation remains elusive, levels of the membrane type 1-MMP i M IIMMl') at the cell surface and of the tissue inhibitor of MMP-2 (TIMP-2) appear to be two important determinants. Inducti...

متن کاملAkt inhibitor deguelin aggravates inflammation and fibrosis in myocarditis
Objective(s): Myocarditis is characterized by inflammatory cell infiltration in myocardial stroma. Attenuation of tumor necrosis factor (TNF)-α and interleukin (IL)-1β is a reliable mark for improving the prognosis. Protein kinase B (Akt) plays an important role in the development and progression of myocarditis. The specific role of the natural inhibitor of Akt, Deguel...
