OBJECTIVE Vitamin D-binding protein (DBP) genetic variants have an influence on vitamin D status and, therefore, they may contribute to the development of autoimmune diseases. In this case-control study, we investigated the association of DBP gene polymorphisms with susceptibility to Graves' disease (GD) in a Polish population. Furthermore, we analyzed the(More)
Diverse genes are candidates for susceptibility to Graves' disease, including the vitamin D receptor (VDR), which regulates the transcription of target genes in response to the active metabolite 1,25(OH)(2)D(3). We analyzed four polymorphisms of the VDR gene (ApaI, TaqI, BsmI, and FokI) in patients with Graves' disease (n = 789) and healthy controls (n =(More)
Recently, a functional polymorphism in the NFKB1 gene promoter (-94ins/del ATTG) has been identified and associated with chronic inflammatory diseases. The aim of this study was to analyze the association of NFKB1 polymorphism with susceptibility to and phenotype of Graves' disease (GD). The initial case-control association study, performed in a(More)
Impaired thermogenesis can promote obesity. Therefore, the aim of this study was to investigate whether the expression of thermogenesis-related genes is altered in adipose tissues of obese individuals and whether excessive methylation of their promoters is involved in this phenomenon. The expression of genes encoding β adrenergic receptors (ADRBs), thyroid(More)
OBJECTIVE Recently, a functional polymorphism in the CD40 gene at position -1, C to T change (C-1T) has been identified and the C/C genotype has been reported to be associated with Graves' disease (GD). DESIGN We performed a case-control, replication study on 556 patients with GD and 611 healthy subjects in a Polish population. Furthermore, we analyzed(More)
OBJECTIVE Aromatase cytochrome P45019 (CYP19) is a key enzyme in estrogen biosynthesis, and polymorphisms within its gene are associated with an increased risk of estrogen-dependent diseases. Enhanced estrogen stimulation of breast tissue in men may lead to gynecomastia. We assessed whether intron 4 (TTTA)n repeat and TCT deletion/insertion polymorphisms(More)
Aging is associated with progressing genomic instability. The XPD gene encodes a DNA helicase involved in nucleotide excision repair and in transcription. We analyzed the common XPD polymorphisms that were previously shown to affect protein’s DNA repair efficiency and to increase the risk of developing various cancers. Analysis was performed in 149(More)
INTRODUCTION Adiponectin demonstrates a protective role against the development of obesity, type 2 diabetes mellitus, and cardiovascular disease. The -11377C 〉 G, -11391G 〉 A, and -11426A 〉 G promoter polymorphisms of ADIPOQ gene influence the level of circulating adiponectin. We examined the level of total and high molecular weight (HMW) adiponectin in(More)
BACKGROUND Women live longer than men. Some possible reasons for this advantage are the protection provided by high concentrations of 17β-estradiol (E2) during the premenopausal period and polymorphic variants of the estrogen receptors (ERs), which mediate various cardiovascular functions of E2. METHODS We tested whether the -351A/G and -397T/C(More)
