The intrapulmonary renin-angiotensin system via tissue concentration of angiotensin II or bradykinin may have multiple effects on pulmonary pathophysiology. Therefore, it was investigated whether the presence of the D allele of the angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism or the A allele of angiotensinogen (AGT) promoter polymorphism (-6)A/G are independent risk...
Background & Aims: Scleroderma is a chronic connective tissue disease with unknown etiology. Vitamin D, a necessary hormone that plays a particular function in the calcium and phosphate homeostasis, is involved in etiology of this disorder. Klotho, co-receptor of fibroblast growth factor 23 (FGF-23), can interfere in calcium and phosphate metabolism. The purpose of this study was to determ...
Background and purpose: Gastric cancer is the most common cancer associated with high mortality worldwide. One of the genes that is down-regulated in gastric cancer, is the SIRT3 that encodes the histone deacetylase enzyme. There is a variable number tandem repeat (VNTR) polymorphism in the intron 5 of SIRT3 gene and evidence shows that expression of SIRT3 gene increases by increase in the numb...
Background & Aims: Behcet's disease (BD) is an autoimmune disease that usually occurs with oral, genital and ocular ulcers. The cause of this disease is unknown and environmental, genetic and immunological factors contribute to its development. In the present study, the relation between rs2910164 and rs57095329 polymorphisms of miR146a gene with the potential for BD was investigated in Iranian ...
Background and Objective: Acute myeloid leukemia (AML) is a clonal proliferation of immature myeloid progenitors in the bone marrow. Multiple genetic and environmental factors have been reported to be involved in the pathogenesis of AML. Cytochromes, such as cytochrome P450 are among detoxifying enzymes whose aberrant expression can make individuals susceptible to a variety of cancers and leuke...
Background and purpose: CYP1B1 is involved in the metabolism of exogenous and endogenous substrates and plays a key role in hormone and xenobiotic induced carcinogenesis. Polymorphisms in CYP1B1 could result in modifications in its enzyme activity and are known to be associated with cancer susceptibility related to environmental toxins and hormone exposure. Moreover, the association of CYP1B1 p...
PURPOSE Recent literature suggests a genetic component for non-arteritic anterior ischemic optic neuropathy (NAION). We examined the association of the insertion/deletion (I/D) polymorphism of the angiotensin-converting enzyme gene, of the M235T polymorphism of the angiotensinogen gene, and of the A1166C polymorphism of the angiotensin II type 1 receptor gene with NAION. METHODS Forty-seven p...
The aim of the current study was to investigate the association between the InDel polymorphism in the angiotensin I-converting enzyme gene (ACE) and the rs699 polymorphism in the angiotensinogen gene (AGT) and diabetes mellitus type 2 (DM2) in a sample population from Southern Brazil. A case-control study was conducted with 228 patients with DM2 and 183 controls without DM2. The ACE InDel polym...
Introduction: Migraine is a common debilitating headache with reversible pain attacks associated with temporal changes in the diameter of head blood vessels. According to the International Classification for the Headache Society, migraineurs are divided into two main categories: migraine with aura and migraine without aura. The present study aimed to investigate the association between COX-2-7...
BACKGROUND Epidemiologic studies have shown the association between alcohol consumption and colorectal cancer, especially for rectal cancer. The alcohol related enzyme encoding gene ALDH2 has polymorphism Glu487Lys, and 487Lys allele is closely linked with phenotypic loss of enzyme activity. MATERIALS AND METHODS A hospital-based case-control study was conducted with 72 colon and 70 rectal ca...
