Motivation. Our previous study showed differences in the atherosclerosis phenotype between Lithuanian and Swedish men that could be influenced by complementary factors, namely oxidation processes and/or oxidative stress. The goal of this study was to evaluate the mainstream biological pathways inducing and maintaining the atherosclerotic process by analyzing genetic biomarkers particularly in inflammatory and metabolic pathways where the main focus is laid on the oxidation process. Methods. There were 32 families recruited for the study and clinical as well as biochemical analyses were performed. For genetic analysis 150 SNPs in 89 genes were selected in order to construct a microarray based on Arrayed Primer Extension (APEX) genotyping technology. Genotyping was carried out in 28 families and transmission disequilibrium test (TDT), siblingTDT (STDT), and combined analysis were performed. Results. Clinical and biochemical analysis revealed that probands with premature CAD were more likely to have diabetes mellitus, arterial hypertension, dyslipidemia and were male with high body mass index. Genetic analysis showed six SNPs statistically significantly associated with the atherosclerosis phenotype in the candidate genes ITGA2, IL1B, ALOX5A, OR13G1, MMP9 and NFKB1. These genes belong to different biological pathways: trombocyte adhesion and vessel damage, inflammation response, cholesterol and lypoxygenase metabolic pathway and nutrition. Conclusions. Generalized clinical, biochemical, bioinformatical and candidate genes association results support our hypothesis and indicate that the oxidation process may be of key importance in the formation of atherosclerosis., Ingrida Pepalyte, Zita Aušrele Kučinskiene, Kristina Grigalioniene, Žaneta Petrulioniene, Vilma Dženkevičiute, Loreta Bagdonaite, Vaidutis Kučinskas, and Literatura
Purpose: To investigate the protective action of Ceruloplasmin (Cp) on the lysis of erythrocytes in men with prostate tumors. Material and Methods: The blood erythrocytes of the patients with benign hyperplasia of prostate (BHP) and prostate adenocarcinoma (CaP) were studied. Patients at the age 60-75 with early stages of a cancer have been investigated. The control group was consisted of apparently healthy males with the compatible age. n=15 for each group. The clinical stage of the disease was diagnosed by means of rectal, histological and echographic examination of the prostate gland. Photometric methods were applied to register lysis dynamics in order to test out the protective action of Cp. Results: The nonspecific protective function of Cp preparation on BHP and CaP erythrocytes as well as on the control group erythrocytes was revealed. CaP erythrocytes have shown more sensitivity to the lysis provocative factor than BHP and the control group erythrocytes, that was presumably attributed to the structural and functional changes of the erythrocytes developed in the presence of malignant tumor., N.
