Several findings link SLE and RA development with the complement system and ficolin components have emerged as candidates for disease development. Since genetic association studies with ficolin genes in SLE and RA have not yet been conducted in a Brazilian population, the aim of this study was to determine whether polymorphisms of ficolin-1(FCN1) and ficolin-2 (FCN2) genes are associated with SLE and RA susceptibility as well as disease manifestation. Two SNPs within FCN1 (rs2989727 and 1071583) and three in FCN2 (rs17514136, rs3124954, and rs7851696) were studied in 208 SLE and184 RA patients as well as 264 healthy individuals in a Southeast Brazilian population. For SLE patients, the FCN2 rs17514136 SNP was associated with a more severe disease (SLICC) (p = 0.0067). Furthermore, an association between the occurrence of nephritis and the T/T genotype for FCN2 rs3124954 SNP (p = 0.047, OR = 3.17, 95%CI = 1.34-7.5) was observed. No association was observed between the studied polymorphisms and RA development. Thus, our data support involvement of the FCN2 gene in the SLE phenotype.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/26464189?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Cavalcanti, Catarina Addobbati Jordão</style></author><author><style face="normal" font="default" size="100%">De Azevêdo Silva, Jaqueline</style></author><author><style face="normal" font="default" size="100%">de Barros Pita, Will</style></author><author><style face="normal" font="default" size="100%">Veit, Tiago Degani</style></author><author><style face="normal" font="default" size="100%">Monticielo, Odirlei Andre</style></author><author><style face="normal" font="default" size="100%">Xavier, Ricardo Machado</style></author><author><style face="normal" font="default" size="100%">Brenol, João Carlos Tavares</style></author><author><style face="normal" font="default" size="100%">Brenol, Cleiton Viegas</style></author><author><style face="normal" font="default" size="100%">Fragoso, Thiago Sotero</style></author><author><style face="normal" font="default" size="100%">Barbosa, Alexandre Domingues</style></author><author><style face="normal" font="default" size="100%">Duarte, Ângela Luiza Branco Pinto</style></author><author><style face="normal" font="default" size="100%">Oliveira, Renê Donizeti Ribeiro</style></author><author><style face="normal" font="default" size="100%">Louzada-Júnior, Paulo</style></author><author><style face="normal" font="default" size="100%">Donadi, Eduardo Antônio</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Chies, José Artur Bogo</style></author><author><style face="normal" font="default" size="100%">Sandrin-Garcia, Paula</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Vitamin D receptor polymorphisms and expression profile in rheumatoid arthritis brazilian patients.</style></title><secondary-title><style face="normal" font="default" size="100%">Mol Biol Rep</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Mol.

RA displays important genetic background with a variety of genes contributing to the immune balance breakdown. Recent studies have demonstrated that vitamin D, through its receptor (VDR), is able to regulate the immune balance and suppress the autoimmunity process, being a potential target in autoimmune diseases. In the present genetic association study, we assessed 5 Tag single nucleotide polymorphisms (SNPs) (rs11168268, rs2248098, rs1540339, rs4760648 and rs3890733), which cover most of the VDR gene, in three different Brazilian populations (from Northeast, Southeast and South Brazil). We also evaluated the VDR expression profile in whole blood and monocytes from RA patients. For genotyping study, 428 RA patients and 616 healthy controls were genotyped with fluorogenic allele specific probes on an ABI7500 platform. For gene expression study, VDR mRNA levels of 15 RA patients and 26 healthy individuals were assessed by RT-PCR. Our results showed that SNPs rs4760648 and rs3890733 are associated to RA susceptibility (p value = 0.0026, OR 1.31 and p value = 0.0091, OR 1.28 with statistical power = 0.999 and 0.993, respectively). Regarding RA clinical features, the studied SNPs did not show significant associations. The gene expression assays showed that VDR mRNA levels were down regulated in both whole blood (-3.3 fold) and monocytes (-3.2 fold) of RA patients when compared to healthy controls. Our results, the first reported for distinct Brazilian populations, support a role of the VDR gene in the susceptibility to RA.&lt;/p&gt;</style></abstract><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/26686848?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">De Azevêdo Silva, Jaqueline</style></author><author><style face="normal" font="default" size="100%">Pancotto, João Alexandre Trés</style></author><author><style face="normal" font="default" size="100%">Donadi, Eduardo Antônio</style></author><author><style face="normal" font="default" size="100%">Crovella, Sergio</style></author><author><style face="normal" font="default" size="100%">Sandrin-Garcia, Paula</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">LIG4 and RAD52 DNA repair genes polymorphisms and systemic lupus erythematosus.</style></title><secondary-title><style face="normal" font="default" size="100%">Mol Biol Rep</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Mol.

Nevertheless, SLE might also be triggered due to environmental factors, such as UV light exposure. DNA double strand breaks (DSBs) may be induced secondarily by UV radiation, increasing DNA immunogenicity and in SLE patients DNA repair is diminished, allowing the accumulation of DSBs and genomic instability. LIG4 and RAD52 genes play important roles in DNA repair mechanisms and a recent microarray analysis showed their differential expression in active SLE patients. In this study we investigated a potential association between LIG4 and RAD52 single nucleotide polymorphisms (SNPs) and SLE predisposition in a Southeast Brazilian population. We assessed four Tag SNPs in LIG4 and three in RAD52 gene region, encompassing most of the gene sequence, in 158 SLE patients and 212 healthy controls. We also performed SNPs analysis considering clinical manifestation, gender and ethnicity in SLE patients. Our data did not show association between LIG4 and RAD52 SNPs and SLE, its clinical manifestations or ethnicity in the tested population. The analysis regarding ethnicity and SLE clinical manifestations indicated Caucasian-derived patients as more susceptible to cutaneous and hematological alterations than the African-derived. To our knowledge, this is the first association study involving LIG4 and RAD52 genes and SLE predisposition.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24415301?dopt=Abstract</style></custom1></record></records></xml>
