BACKGROUND The adenosine triphosphate-binding cassette transporter A1 (ABCA1) protein plays an important role in the first step of the reverse cholesterol transport system. AIMS We studied the association of four polymorphisms in the ABCA1 gene (G1051A, G2706A, G2868A and -565C/T) with lipid profile and coronary artery disease. METHODS Overall, 316(More)
Mercury has been recognized as an industrial hazard that adversely affects male reproductive systems of humans and animals. However, less information is available concerning the underlying mechanism in the pathogenesis of male reproductive dysfunction. The present study investigated the possible involvement of oxidative stress to induce oxidative(More)
Although it is established that in utero exposure to antiandrogenic compounds such as flutamide induces hypospermatogenesis in adult male rat offspring, the cellular and molecular mechanisms remain to be investigated. By using adult rats exposed in utero to flutamide (0.4, 2, 10 mg/kg.d) as a model, we show that the hypospermatogenesis could be related to a(More)
BACKGROUND The role of cholesteryl ester transfer protein (CETP) in the development of atherosclerosis is undergoing debate. AIMS In this prospective study, we sought to explore the role of the CETP Taq1B variant in coronary artery disease risk, and its association with plasma lipid and apolipoprotein concentrations. METHODS DNA was extracted from 316(More)
Steroid-resistant nephrotic syndrome (NS) remains one of the most intractable causes of end-stage renal disease in the first two decades of life. Several genes have been involved including NPHS1, NPHS2, WT1, PLCE1, and LAMB2. Our aim was to identify causative mutations in these genes, in 24 children belonging to 13 families with NS manifesting with various(More)
Haptoglobin (Hp) polymorphism generates three common human genotypes (Hp1-1, Hp2-1, and Hp2-2), having functional differences, related to the risk of development of cardiovascular diseases. These functions are a consequence of hemoglobin binding that leads to the synthesis of an antioxidant like ferritin. We explored the association of Hp polymorphism with(More)
Leptin is a key hormone of weight regulation that modulates food intake. Since the elaboration of the leptin action mechanism, several studies tried to establish the relationship between obesity and the common polymorphisms of leptin (LEP) and leptin receptor (LEPR) genes, but results were controversial. We studied the association of G2548A of the LEP gene(More)
Resistin is an adipocyte-secreted cytokine recently discovered and has been proposed as a link between obesity and diabetes. Many resistin gene polymorphisms were described and their implication in obesity and metabolic syndrome (MetS) was controversial. Our aim was to study the relationship between four resistin polymorphisms (420C/G, 44G/A, 62G/A, and(More)
AIMS The aim of the present study was to investigate hyperhomocysteinemia in Tunisian bipolar I patients according to 5,10-methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism. METHODS The subjects consisted of 92 patients with bipolar I disorder diagnosed according to DSM-IV, and 170 controls. Plasma total homocysteine, folate and vitamin B12(More)
BACKGROUND Primary hyperoxaluria type I (PH1) is a rare genetic disorder characterized by allelic and clinical heterogeneity. Four mutations (G170R, 33_34insC, I244T and F152I) account for more than 50% of PH1 alleles and form the basis for diagnostic genetic screening for PH1. We aimed to analyze the prevalence of these specific mutations causing PH1, and(More)
