The process of aging is one of the most complex and intriguing biological phenomenons. Aging is a genetically regulated process in which the organism's maximum lifespan potential is pre-determined, while the rate of aging is influenced by environmental factors and lifestyle. Considering the complexity of mechanisms involved in the regulation of aging(More)
Down syndrome (DS, also known as trisomy 21) most often results from chromosomal nondisjunction during oogenesis. Numerous studies sustain a causal link between global DNA hypomethylation and genetic instability. It has been suggested that DNA hypomethylation might affect the structure and dynamics of chromatin regions that are critical for chromosome(More)
Previous findings regarding the role of TNF-alpha-308 gene polymorphism in multiple sclerosis (MS) are contradictory. The aim of this study was to investigate the possible influence of TNF-alpha-308 polymorphism on MS susceptibility and the MS disease process in a Croatian and Slovenian population. Genotyping was performed in 338 patients and 460 healthy(More)
Nine Y-chromosome STR loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385 and YCAII) were analysed in a sample of 101 unrelated males from Croatia. Allelic frequencies and gene diversities for each Y-STR locus and haplotype diversity were determined. Ninety-one different haplotypes were obtained from 101 unrelated males and 84 haplotypes(More)
Several studies investigating the role of the CCR5delta32 mutation in multiple sclerosis (MS) have reported varied, often contradictory results. Therefore in the present study we have analysed whether the CCR5delta32 mutation is associated with the risk of/or disease process in Croatian and Slovene MS patients. Three hundred and twenty-five MS patients and(More)
OBJECTIVES Angiotensin-converting enzyme (ACE) activity is increased in blood and cerebrospinal fluid of patients with multiple sclerosis (MS). In addition, in experimental autoimmune encephalomyelitis (EAE), an animal model of MS, the blockade of ACE suppresses the disease itself. To analyze the genetic association of the ACE gene with MS, we examined ACE(More)
The interleukin 7 receptor alpha single nucleotide polymorphism rs6897932 was identified as a multiple sclerosis susceptibility-modifying polymorphism in genome-wide and gene scan studies, mainly in populations in western countries. The aim of this study was to investigate the association of interleukin 7 receptor alpha rs6897932 with multiple sclerosis in(More)
Polymorphisms in the CTLA-4 gene are known to be important in several autoimmune diseases, including multiple sclerosis (MS). Previous studies on the impact of CTLA-4 +49 A/G gene polymorphism have given contradictory results. We investigated the possible influence of this polymorphism on MS susceptibility and disease behaviour in Croatian and Slovenian(More)
The aim of the study was to examine frequencies of HLA-A, -B, -DR antigens and haplotypes in population of Rijeka and to compare them with general Croatian and European populations. The subjects were 117 unrelated healthy blood donors. The antigens with the highest frequencies were: A2 (27.2%), A9 (16.3%), B5 (14.8%), B12 (11.8%), B18 (11.8%), DR5 (21.6%)(More)
