In addition to decreased insulin sensitivity, diabetes is a pathological condition associated with increased inflammation. The ω-3 fatty acids have been proposed as anti-inflammatory agents. Thus, the major goal of this study was to analyze the effects of fatty acid supplementation on both insulin sensitivity and inflammatory status in an animal model of(More)
Previous studies have demonstrated that interleukin-15 (IL-15) has important anabolic effects on muscle protein metabolism. In the present investigation we have analysed the effects of IL-15 on glucose metabolism in skeletal muscle. Administration of a single dose of the cytokine (100 microg/kg body weight) resulted in a 32% increase on glucose uptake (as(More)
The CD5 lymphocyte surface receptor is a group B member of the ancient and highly conserved scavenger receptor cysteine-rich superfamily. CD5 is expressed on mature T and B1a cells, where it is known to modulate lymphocyte activation and/or differentiation processes. Recently, the interaction of a few group B SRCR members (CD6, Spalpha, and DMBT1) with(More)
Interleukin 15 (IL-15) has previously been shown to have important effects on lipid metabolism in adipose tissue, particularly influencing the rate of the de novo fatty acid synthesis. The results presented here show that chronic administration to rats (100 microg/kg body weight) has important effects on the metabolic fate of an exogenous [(14)C]-triolein(More)
OBJECTIVES Interleukin-15 (IL-15) plays an important role in lipid metabolism as its administration to rats causes a marked depletion of white adipose tissue (WAT). This reduction in fat mass seems to be caused by and related to hipotriglyceridemia as a result of a lower hepatic lipogenesis and an increased fatty acid oxidation. We have previously observed(More)
Implantation of a fast growing tumour to mice (Lewis lung carcinoma) resulted in a clear cachectic state characterized by a profound muscle wasting. This was accompanied by a significant increase in both UCP2 and UCP3 gene expression in skeletal muscle and heart. Interestingly, this increase in gene expression was not linked to a rise in circulating fatty(More)
The mRNA content of both TNF-alpha and its receptors (TNFR1 and TNFR2) in skeletal muscle and adipose tissue from cachectic rats has been assessed. The implantation of the Yoshida AH-130 ascites hepatoma resulted in substantial decrease in skeletal muscle TNF-alpha expression as early as at day 2 following tumour implantation. However, the mRNA content for(More)
BACKGROUND & AIMS Resveratrol has been reported to have antitumoural effects and recently it has been demonstrated that resveratrol partially blocks skeletal muscle wasting by interfering with NF-kappaB activation. We decided to investigate the potential anti-wasting properties of resveratrol on different models of cancer cachexia in experimental animals.(More)
Implantation of the Yoshida AH-130 ascites hepatoma to rats resulted in a decrease in muscle weight 7 days after the inoculation of the tumor. These changes were associated with increases in the mRNA content for both peroxisome proliferator-activated receptor (PPAR) ; and PPARD in skeletal muscle. The increase in gene expression for these transcription(More)
