BACKGROUND KIR2DS5 gene encodes an activating natural killer cell receptor whose ligand is not known. It was recently reported to affect the outcome of hematopoietic stem cell transplantation. METHODOLOGY/PRINCIPAL FINDINGS In our studies on KIR2DS5 gene associations with human diseases, we compared the frequencies of this gene in patients and relevant(More)
Natural killer (NK) cells are the most abundant lymphocyte population in the decidua. These cells express killer immunoglobulin-like receptors (KIRs), which upon recognition of HLA class I molecules on trophoblasts may either stimulate NK cells (activating KIRs) or inhibit them (inhibitory KIRs) to produce soluble factors necessary for the maintenance of(More)
The evaluation of superoxide dismutase (SOD) activity, as one of the most important antioxidative defence enzymes, in seminal plasma of patients consulting for male infertility was presented in the article. The study included also the determination of its influence on selected human semen quality parameters. The material represents semen samples obtained(More)
VEGF is an important angiogenic cytokine with a critical role in tumor angiogenesis. VEGF concentrations were measured using an ELISA assay, detecting VEGF165 isoform, in tumor cyst and/or ascitic fluids and in sera of 86 patients with malignant neoplasms and in 53 patients with benign ovarian neoplasms. VEGF levels were significantly elevated in the sera(More)
BACKGROUND In in vitro studies it has been revealed that p53 protein expression might regulate topoisomerase I (topo I) and topoisomerase IIalpha (topo IIalpha) levels in tumor cells. So far, the association between the p53 protein and topo I and topo IIalpha expression and its impact on ovarian carcinoma progression has not been analyzed. OBJECTIVES The(More)
In 44 patients with advanced ovarian carcinoma (OC) a fraction of CD45RO+ lymphocytes in the blood and peritoneal carcinomatous fluid (PCF) was investigated. Thirty-one patients received cisplatinum with cyclophosphamide ± doxorubicin. This group was followed from 2.2 to 9 years (mean: 45 months). In 23 out of 31 patients, the percentage of CD45RO+(More)
INTRODUCTION The modification of p53 protein by phosphorylation plays an important role in its stabilization and the regulation of its biological properties. The study investigated the expression of p53 protein phosphorylated at serine 20 (Ser20) and Ser392 and the association between clinicopathological parameters of ovarian neoplasms with respect to p53(More)
BACKGROUND Degradation of the basement membrane and surrounding extracellular matrix is likely to represent a key step in cancer invasion and metastasis. The purpose of this study was to determine whether gastric cancer tissues demonstrate higher cysteine proteases activities: cathepsins B and L during cancer progression in compression with non-cancerous(More)
Spontaneous abortion is the most common complication of human pregnancy. Natural killer (NK) cells expressing killer immunoglobulin-like receptors (KIRs), which may recognize HLA-C (i.e. its C1 or C2 groups) on trophoblast cells, constitute a large leukocyte population in the endometrium. This study investigated whether genetic polymorphisms in the KIR and(More)
The presence of interleukin (IL)-6 in peritoneal carcinomatous fluid (PCF) and its effect on immune cells composition in PCF in patients with advanced ovarian carcinoma was studied. In 21 out of 30 ovarian carcinoma patients, PCF IL-6 levels were found to exceed those seen in PCFs of patients with gastrointestinal cancer. IL-6 activity was higher in(More)
