OBJECTIVE To investigate tumor microenvironment of metastasis (TMEM) and the expression of SPARC (secreted protein acidic and rich in cysteine) in gastric cancer, and their relationships with hematogenous metastasis. PATIENTS AND METHODS Twenty-six pairs of cases with gastric cancer were enrolled, in which there were 26 cases with distant organ metastases and 26 cases of gastric cancer withou...

AIM The aim of the present study was to investigate the efficacy of the traditional Chinese medicine (TCM), astragaloside IV (AS-IV) and curcumin on tumor growth and angiogenesis in an orthotopic nude-mouse model of human hepatocellular carcinoma (HCC). We have previously shown the usefulness of orthotopic models of human cancer for evaluation of the efficacy of TCM. MATERIALS AND METHODS Nud...

Basal cell carcinoma (BCC) is currently the most common cutaneous cancer found in humans. Although it generally shows a relatively benign course (BCCl), some cases show aggressive behavior (BCC2). Until recently, traditional histologic diagnostic criteria have failed to discriminate unequivocally between BCC 1 and BCC2. In this study we selected 50 cases of BCC and categorized them into tw...

BACKGROUND Breakdown of extracellular matrix (ECM) is one of the important hallmarks of cancer progression which facilitates the invasion of tumoral cells to the surrounding tissue. Matrix metalloproteinases (MMPs) can degrade various components of the ECM and basement membrane. The aim of this study was to determine the role of matrix metalloproteinases-9 protein in the biologic behavior of or...

9022 Background: Osteosarcoma, the most frequent primary malignant bone tumor is a chemotherapy-sensitive tumor with survival rates reaching 50 to 80 %. Several reports have demonstrated that neovascularization assessed by intratumoral microvessel density (MVD) correlates with clinicopathological factors and the patients' prognosis in a variety of tumors. However, the role of angiogenesis in os...

Endothelial barrier restoration reverses microvessel hyperpermeability and facilitates recovery from lung injury. Because inhibiting connexin 43 (Cx43)-dependent interendothelial communication blunts hyperpermeability in single microvessels, we determined whether endothelial Cx43 levels correlate with changes in microvessel permeability during recovery from lung injury. Toward this, bacterial e...

Zeng, Min, Hong Zhang, Clifford Lowell, and Pingnian He. Tumor necrosis factor-induced leukocyte adhesion and microvessel permeability. Am J Physiol Heart Circ Physiol 283: H2420–H2430, 2002. First published August 8, 2002; 10.1152/ajpheart.00787.2001.—The objective of this study was to investigate whether leukocyte adhesion and/or emigration are critical steps in increased microvessel permeabi...

To determine whether vascular endothelial growth factor (VEGF) expression and microvessel density are predictive of prognosis in cases of invasive cervical cancer, correlations among VEGF expression, microvessel density, and clinicopathological parameters were identified. VEGF expression was evaluated in 50 cervical cancer samples by immunohistochemical staining. Microvessel density was assesse...

BACKGROUND Angiogenesis is essential for development, growth and advancement of solid tumors. During angiogenesis, ETS-1 is strongly expressed in vascular endothelial cells and the adjacent interstitial cells, while the inhibition of ETS-1 expression leads to suppression of angiogenesis. This prompted us to study the clinical implications of ETS-1 in relation to angiogenesis in uterine endometr...

The importance of the vasa vasorum and blood supply to wall human saphenous vein (hSV) used for coronary artery bypass grafting (CABG) is briefly discussed. This in context possible physical link connecting with lumen hSV anti-ischaemic impact this microvessel network CABG.
