White adipose tissue and liver are important angiotensinogen (AGT) production sites. Until now, plasma AGT was considered to be a reflection of hepatic production. Because plasma AGT concentration has been reported to correlate with blood pressure, and to be associated with body mass index, we investigated whether adipose AGT is released locally and into(More)
Conjugated linoleic acid (CLA) mixtures demonstrated antiatherogenic properties in several animal models, including hamsters, but the mechanism of action of the main food-derived CLA isomer is unknown in this species. This study thus focused on cis-9,trans-11-CLA (rumenic acid), and its effect was compared with that of fish oil, which is known to influence(More)
BACKGROUND Information is lacking on the potential effect of n-3 polyunsaturated fatty acids (PUFAs) on the adipose tissue of patients with type 2 diabetes. OBJECTIVE We evaluated whether n-3 PUFAs have additional effects on adiposity, insulin sensitivity, adipose tissue function (production of adipokines and inflammatory and atherogenic factors), and(More)
Although antipsychotics are established drugs in schizophrenia treatment, they are admittedly known to induce side effects favoring the onset of obesity and worsening its complications. Despite potential involvement of histamine receptor antagonism, or of other neurotransmitter systems, the mechanism by which antipsychotic drugs increase body weight is not(More)
Second-generation antipsychotics are widely used in the treatment of all forms of psychoses, but they often produce undesirable side effects, among which are weight gain and other elements of metabolic syndrome. The mechanisms of these adverse effects are not known. The liver and adipose tissue are the principal candidate organs implicated in the(More)
A rat lipoprotein lipase (LPL)-encoding cDNA (LPL) has been entirely sequenced and compared to the sequences of all the LPL cDNAs reported in other species. As expected, high homology was found between the coding exons. The putative catalytic triad, Ser132, Asp156, His241, according to human numbering, is conserved in rat. As is the case in mouse, an Asn444(More)
Obesity is a leading cause of death worldwide because of its associated inflammatory disorders such as hypertension, cardiovascular and kidney diseases, dyslipidemia, glucose intolerance, and certain types of cancer. Adipose tissue expresses all components of the renin-angiotensin system necessary to generate angiotensin (Ang) peptides for local function.(More)
Although obesity is associated with overactivation of the white adipose tissue (WAT) renin-angiotensin system (RAS), a causal link between the latter and systemic insulin resistance is not established. We tested the hypothesis that overexpression of angiotensinogen (Agt) from WAT causes systemic insulin resistance via modulation of adipose inflammation.(More)
In a previous study, we have demonstrated that a supplementation of a high-fat diet with a quinoa extract enriched in 20-hydroxyecdysone (QE) or pure 20-hydroxyecdysone (20E) could prevent the development of obesity. In line with the anti-obesity effect of QE, we used indirect calorimetry to examine the effect of dietary QE and 20E in high-fat fed mice on(More)
Besides their well-known effect in the molting control in insects, ecdysteroids are steroid hormones that display potential pharmacologic and metabolic properties in mammals. The most common ecdysteroid, 20-hydroxyecdysone (20E) is found in many plants such as quinoa. The aim of the present study was to investigate the ability of quinoa extract (Q) enriched(More)
