Background The aim of the this study was to analyse if there is an association between angiotensin converting enzyme (ACE) insertion/deletion (I/D) polymorphism (287 base pairs, on chromosome 17q23, intron 16 (rs4340)) with asthma severity. ACE plays a vital role in the renin-angiotensinsystem (RAS) which regulates blood pressure by converting angiotensin I into a powerful vasoconstrictor angio...

Gastric cancer (GC) is a common cancer affecting patients around the world. The pathogenesis of gastric cancer has not been understood completely. Genetic mutations and the inflammation induced by Helicobacter pylori (HP) seem to play important roles. The cytokine Interleukin-4 (IL-4) has effects in inflammation, allergies and cancer including GC. The association of IL-4 -590 C>T polymorphism a...

Background: The anti-inflammatory cytokine, interleukin 10 (IL 10), has a crucial role in periodontal diseases. gene coding for this cytokine is pleomorphic. In the promoter region of IL gene, two single nucleotide polymorphisms (SNPs), IL10 1082 and 819, have been discovered to affect expressions. Objective: To investigate association (IL-10-1082 G/A IL-10-819 C/T) with CPO. Patients Methods: ...

Non-alcoholic fatty liver disease (NAFLD), the most common form of disease, is now recognized as a major public health problem worldwide. Tumor necrosis factor alfa (TNF-α), member TNF/TNFR cytokine family, an intercellular transmission molecule that has been reported in wide range human noninfection diseases. The aim study was to determine circulating levels TNF-α and nature its relationships ...

A single nucleotide polymorphism in the promoter of the multifunctional cytokine Interleukin 4 (IL4) affects the binding of NFAT, a key transcriptional activator of IL4 in T cells. This regulatory polymorphism influences the balance of cytokine signaling in the immune system, with important consequences-positive and negative-for human health. We determined that the NFAT binding site is unique t...
