Interleukin-17 (IL-17) is a proinflammatory cytokines produced by T helper 17 (Th17) cells, which plays an important role in both innate and adaptive immune systems. Genetic variants in the IL-17 genes may influence the immunopathogenesis of many cancers. In our study, we investigated the association of three single-nucleotide polymorphisms (SNPs: -152 G/A,(More)
Vitamin D receptor (VDR) polymorphisms have been inconsistently investigated in type 1 diabetes (T1D). However, the results are inconsistent and inconclusive. The current study aimed to investigate the role of TaqI, BsmI, ApaI and FokI VDR polymorphisms in T1D disease. Following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)(More)
The human matrix metalloproteinases (MMPs) are importantly involved in aneurysm formation. Since the clinical manifestations in Behçet disease (BD) include aneurysm formation among major symptoms, polymorphisms in MMP-9 might be associated with BD susceptibility. The aim of the current case-control study was to investigate the association of four single(More)
Transgene integration into plant genomes is a complex process accompanied by molecular rearrangements. Classic methods that are normally used to study transgenic population genetics are generally inadequate for assessing such integration. Two major characteristics of transgenic populations are that a transgenic genome may harbor many copies of the transgene(More)
The association between vitamin D receptor (VDR) polymorphisms and asthma risk has been inconsistently investigated, but published studies demonstrated conflicting results. The aim of the current study was to investigate the impact of TaqI, BsmI, ApaI, and FokI VDR polymorphisms on asthma disease by using a meta-analysis approach. Following the preferred(More)
Recent genetic surveys have identified vitamin D receptor (VDR) as a susceptibility gene for several autoimmune diseases. This study was designed to investigate the association of VDR gene polymorphisms with Behçet's disease (BD) and Rheumatoid arthritis (RA). A case-control study including 151 BD, 106 RA patients and an appropriate number of healthy(More)
Vitamin D receptor (VDR) polymorphisms have been studied as potential contributors to multiple sclerosis (MS). However, published studies differ with respect to study design and the significance of the effects detected. The aim of this study was to quantify the magnitude of the risk associated with the TaqI, BsmI, ApaI and FokI VDR polymorphisms in MS using(More)
PURPOSE Asthma is a complex disease, with contributions from multiple genes, various genetic backgrounds, and environmental factors. Many human epidemiological studies have demonstrated that single nucleotide polymorphisms (SNPs) in Toll-like receptor (TLR) genes are inconsistently associated with asthma risk. Some have demonstrated differences concerning(More)
Many studies reported that Vitamin D Receptor (VDR) gene polymorphisms might influence the cancer risk due to their antiproliferative, antiangiogenic, and apoptotic effects. The aim of this study was to explore the genetic association of VDR polymorphisms with lung cancer risk in Tunisian population. The genotype and haplotype frequencies of four VDR(More)
BACKGROUND Vitamin D receptor (VDR) polymorphisms have been inconsistently investigated in rheumatoid arthritis (RA). However, published studies demonstrated differences concerning design and effect size. A meta-analysis is necessary to determine the magnitude of the association between VDR polymorphisms and RA risk. OBJECTIVE The aim of the current study(More)
