PURPOSE Tumor cells, including colorectal cancer (CRC), are able to produce and release matrix metalloproteinase 9 (MMP-9) which is involved in tumor invasion and metastasis. Natural tissue inhibitors of matrix metalloproteinases (TIMPs) regulate activity of MMPs and stimulate tumor growth and malignant transformation. The aim of the present study was to(More)
Esophageal cancer (EC) is one of the most aggressive malignant tumors of the gastrointestinal tract. There are two distinct histological types of EC: esophageal squamous cell carcinoma and adenocarcinoma of the esophagus. Etiologic factors and the patterns of incidence of both subtypes are different. Matrix metalloproteinases (MMPs) and their tissue(More)
The brain being highly sensitive to the action of alcohol is potentially susceptible to its carcinogenic effects. Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) are the main enzymes involved in ethanol metabolism, which leads to the generation of carcinogenic acetaldehyde. Human brain tissue contains various ADH isoenzymes and possess also(More)
BACKGROUND Extracellular gelsolin (GSN) and GC-globulin/Vitamin D-binding protein (DBP) appear to play an important role in clearing the actin from extracellular fluids and in modulating cellular responses to anionic bioactive lipids. In this study we hypothesized that cellular actin release and/or increase in bioactive lipids associated with multiple(More)
BACKGROUND VEGF may play a role in the pathogenesis of cancer disease, for example in cell growth, proliferation and angiogenesis. In this study, we investigated plasma levels of this cytokine in comparison to plasma levels of a new biomarker - HE4 and the established tumor marker CA125 in ovarian cancer patients (100) as compared to control groups:(More)
Gastric cancer (GC) is a second most common cause of cancer-related death and represents an inflammation-driven malignancy. It has been suggested that interleukin 6 (IL-6) and C-reactive protein (CRP) play a potential role in the growth and progression of GC. The aim of the present study was to compare clinical significance of IL-6 and CRP with classic(More)
PURPOSE Plasma levels of selected hematopoietic cytokines: interleukin 3 ( IL-3), stem cell factor (SCF), granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte colony-stimulating factor (G-CSF) and macrophage colony-stimulating factor (M-CSF), and the tumor marker carcinoma antigen 15-3 (CA 15-3) in breast cancer (BC) patients were(More)
Metalloproteinase-9 (MMP-9) is the proteolytic enzyme degrading type IV collagen, and plays important role in the invasiveness and metastatic potential of tumor cells. The aim of the current study was to compare the association between the intensity of MMP-9 expression in neoplastic cells and in the interstitial inflammatory infiltrate cells in esophageal(More)
INTRODUCTION To investigate the hypothesis that atorvastatin decreases blood pressure (BP) values and improves endothelial function assessed by flow-mediated dilation (FMD) in normolipidaemic hypertensive patients. MATERIAL AND METHODS Fifty-six hypertensive patients were randomized in a 2 : 1 proportion to atorvastatin (80 mg/day/3 months; group A; n =(More)
In this study, we compared plasma levels and the diagnostic utility of hematopoietic growth factors (HGFs) with SCC-Ag in cervical cancer patients in relation to control groups and cervical intraepithelial neoplasia (CIN) patients and healthy subjects. Pretreatment plasma levels of HGFs (SCF, GM-CSF, G-CSF and M-CSF) were determined by the use of(More)
