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)
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)
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)
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)
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)
With puromycin aminonucleoside-induced nephrotic syndrome (NS) in rats, twofold elevated levels of lipoproteins were observed. These levels were not related to proteinuria or to plasma albumin levels. Ultrastructural lesions induced in the kidneys by puromycin aminonucleoside were consistent with NS, while there was little or no hepatic involvement.(More)
BACKGROUND & AIMS Previous studies of our research group have shown that apoptosis is present in skeletal muscle of tumour-bearing animals subject to cachexia. For this reason we decided to investigate the apoptosis in skeletal muscle of cancer patients. METHODS AND RESULTS In the present study, muscle biopsies from weight-losing patients with upper(More)
Recent studies have demonstrated the activation of skeletal muscle DNA fragmentation in some catabolic conditions. In an attempt to elucidate if sepsis (a catabolic state) was also associated with muscle apoptosis, sepsis was induced by cecal ligation and puncture, and the results clearly show an induction of DNA fragmentation in gastrocnemius muscle(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)
