Objective: The T allele of a functional polymorphism (rs4988235: LCT-13910 C>T), close to the lactase gene, correlates with lactase persistence (LP) in adults. The LP genotype (TT+TC) has been associated with a higher BMI in European populations in cross-sectional studies. In the French D.

Superoxide dismutase (SOD) enzymes play a major role in detoxification of reactive oxygen species and protection against oxidative stress. Associations of SOD1 gene variants with diabetic nephropathy were reported in patients with type 1 diabetes.

We have now analyzed in a prospective way the influence of dairy product and calcium consumption at inclusion on the 9-year cumulative incidence of the MetS and associated traits in the French prospective study with a 9-year follow-up, DESIR.
Methods: After exclusion of diabetic subjects and those being on a diet at inclusion, 3417 men and women who completed a food frequency at baseline could be studied.
Background: Oxidative stress is involved in the pathophysiology of diabetic nephropathy. The superoxide dismutase (SOD) enzymes play a major role in detoxification of reactive oxygen species and have a protective effect against diabetic nephropathy. We investigated associations of allelic variations in SOD1 gene with nephropathy in patients with type 1 diabetes.

Methods: We observed that GCG, the haplotype based on these polymorphisms and combining the three rare alleles associated with higher natriuretic peptides and lower BP in a recent report, was associated with BNP plasma levels and BP in a French study of 5212 middle-aged participants, Epidemiological Data on Insulin Resistance Syndrome study. With the 9-year follow-up of Epidemiological Data on Insulin Resistance Syndrome study, we were able to analyze the association of incident microalbuminuria (576 patients) and low estimated glomerular filtration rate (<60 ml/min; 246 incident patients) with the tested haplotypes.
Context: The six-transmembrane protein of prostate 2 (STAMP2) has been shown to be involved in insulin resistance in animal models, but in humans, its role is far from understood. Our hypothesis was that genetic variation of STAMP2 could be associated with insulin resistance phenotypes such as the metabolic syndrome (MetS) in humans.
Objective: Our objective was to search for associations between STAMP2 polymorphisms and the MetS in humans.
Background: Adiponectin levels are high in cases of diabetic nephropathy, but it remains unclear whether these high levels are a cause or a consequence of the disease. We investigated the possible association of polymorphisms in the adiponectin gene and baseline adiponectin levels with the incidence of renal events in subjects with type 2 diabetes.
Methods: We studied three adiponectin polymorphisms (-11391G > A, +45T > G and +276G > T) in 3086 subjects with type 2 diabetes and high levels of albumin excretion from the diabetes, hypertension, microalbuminuria or proteinuria, cardiovascular events and ramipril (DIABHYCAR) trial.
Patients with type 2 diabetes mellitus (T2D) have a high coronary risk partly because of low levels of high-density lipoprotein-cholesterol (HDL-C). The adenosine triphosphate-binding cassette transporter A1 (ABCA1) plays a key role in HDL metabolism. We studied the association of common single nucleotide polymorphisms (SNPs) in the ABCA1 gene with HDL-C levels and coronary risk in a cohort of subjects with T2D.
