BACKGROUND Cytokines play a key role in the regulation of immune responses. In hepatitis C virus infection, the production of abnormal cytokine levels appears to contribute in the progression of the disease, viral persistence, and affects response to therapy. Cytokine genes polymorphisms located within the coding/regulatory regions have been shown to affect(More)
Rheumatoid arthritis (RA) is a chronic autoimmune disorder associated with altered expression of pro-inflammatory cytokines. We aim to elucidate the association between the -308G/A polymorphism of the TNF-α gene and 196M/R polymorphism in TNFRII gene and susceptibility and severity of RA. One hundred and seventy-two RA patients and one hundred and sixty(More)
Rheumatoid arthritis (RA) is the most common cause of adult inflammatory arthritis. Recent genome-wide association scans have disclosed several single-nucleotide polymorphisms associated with RA susceptibility. The aim of this study was to determine whether the polymorphisms of TRAF1/C5 (tumor necrosis factor (TNF)-receptor associated factor 1)/(complement(More)
The matrix metalloproteinases 1 and 3 (MMP1 and MMP3) are thought to be important in destructive joint changes seen in rheumatoid arthritis (RA) and osteoarthritis (OA) diseases. The aim of this study was to analyze whether functional polymorphisms in the promoter region of the MMP1 and MMP3 genes were associated with RA and OA. The MMP1 (-1607 1G/2G) and(More)
Recently genetics and epigenetics alterations have been found to be characteristic of malignancy and hence can be used as targets for detection of neoplasia. RAS association domain family protein 1A (RASSF1A) gene hypermethylation has been a subject of interest in recent researches on cancer breast patients. The aim of the present study was to evaluate(More)
BACKGROUND Asthma is a complex multifactorial disease with an obvious genetic predisposition. Polymorphisms of the glutathione-S-transferase (GST) genes are known risk factors for some environmentally-related diseases. The aim of the present study was to investigate the role of polymorphisms in the GSTT1, GSTM1 and GSTP1 genes and asthma susceptibility in(More)
Catechin has anti-inflammatory and antioxidative effects. Cardiotoxicity, which results from intense cardiac oxidative stress and inflammation, is the main limiting factor of the adriamycin use in the treatment of malignant tumors. Thus, the present study aimed to assess the antioxidant and anti-inflammatory effects of catechin on adriamycin-induced(More)
BACKGROUND Host genetic factors may affect clinical outcomes of hepatitis C virus (HCV) infection; however, the possible mechanisms remain largely unknown. This study aimed to evaluate transforming growth factor-β1 (TGF-β1)-509 and tumor necrosis factor-α (TNF-α)-308 genes polymorphisms as a risk factors for cirrhosis and hepatocellular carcinoma (HCC) in(More)
OBJECTIVE To investigate whether peptidyl arginine deiminase type IV gene (PADI4) polymorphisms contribute to rheumatoid arthritis (RA) susceptibility in Egyptians, whether they influence disease severity and activity, and whether they affect anti-mutated citrullinated vimentin antibodies (anti-MCV) level. METHODS Three PADI4 single nucleotide(More)
BACKGROUND Obesity associated insulin resistance is a major risk factor for type 2 diabetes mellitus. Resistin is recently reported to provide a link between obesity, insulin resistance and type 2 diabetes mellitus. We aimed to investigate the possible associations of resistin gene (RETN) polymorphisms with obesity, and to detect whether these polymorphisms(More)
