BACKGROUND CRC caused more than 600,000 estimated deaths in 2008. Dysregulated signaling through the RAS/RAF/mitogen-activated protein kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway due to mutations in K-Ras and B-Raf are common events in CRC. METHODS Incidence of mutations in codons 12 and 13 of K-Ras and exons 11 and 15 of(More)
BACKGROUND Overexpression of epidermal growth factor receptor (EGFR) is found in many types of neoplasms. The aim of the study was to evaluate EGFR expression in colorectal cancer (CRC) specimens and to determine whether EGFR expression correlates with clinicopathological data and overall survival. PATIENTS AND METHODS Tissue specimens from 181(More)
OBJECTIVE To compare the expression level of the most relevant angiogenesis-related genes in the eutopic endometrium of women with and without endometriosis. STUDY DESIGN 32 regularly menstruating patients (18 with endometriosis and 14 controls) underwent surgery in the proliferative phase of the cycle. Eutopic endometrium was collected by the use of(More)
OBJECTIVE To determine the concentrations of cathepsins B, D and G in proliferative eutopic endometrium of patients with and without endometriosis, by use of the surface plasmon resonance imaging (SPRI) technique. STUDY DESIGN A total of 55 patients were recruited in the study: 31 patients with endometriosis (stages I-IV) and 24 controls. Endometrial(More)
The aim of this study was to selectively profile the activation status of mammalian target of rapamycin (mTOR)-associated oncogenes and tumor suppressor genes (TSGs) in ovarian cancer specimens, healthy ovaries and benign ovarian tumors, including endometrial cysts. We used a novel type of microfluidic gene array to examine the expression of 15 human tumor(More)
PURPOSE BK polyomavirus (BKV) infection and BKV-associated nephropathy (BKVAN) are among the most important problems in renal transplantation. We aimed to determine the incidence of BK viruria, viremia, and BKVAN in renal transplant recipients in the northeastern part of Poland. METHODS Urine and blood samples from 126 cadaveric renal transplant(More)
BACKGROUND The oxidative modifications of bioactive macromolecules have important roles in carcinogenesis. Of particular interest are lipid peroxidation products, which are involved in the activation of Nrf2 and endocannabinoids that affect cancer progression. METHODS In lung cancer tissues (squamous cell lung carcinoma - SCC and adenocarcinoma - AC), the(More)
In recent years the the set of diagnostic tools in colorectal cancers has been extended by the assessment of the KRAS gene status. Currently it is a necessary step in order to qualify patients for the targeted therapy. The results of the analysis of several studies revealed a high rate of compliance of the KRAS gene mutational status in primary and(More)
The incidence of malignant gastrointestinal cancers in Poland has been constantly growing, which has led to an intensification of the search for new markers of the early clinical stage of this disease. The oral cavity,as the first part of the gastrointestinal tract, has a very important role. The oral cavity presents symptoms of both typically(More)
PURPOSE Numerous genetic and endocrine factors are involved in the process of testicular descent, but only a few genetic causes have been reported in human. The aim of this study was to investigate the density and distribution of single nucleotide polymorphisms (SNPs) anti-Müllerian hormone (AMH) and AMHRII receptors in cryptorchid patients and determine(More)
