Uncoupling protein (UCP) 3 is a mitochondrial inner membrane protein implicated in lipid handling and metabolism of reactive oxygen species. Its transcription is mainly regulated by peroxisome proliferator-activated receptors (PPAR), a family of nuclear hormone receptors. Employing bandshift assays, RNA interference and reporter gene assays we examine an intronic region in the UCP3 gene harbori...
UCP2 and UCP3, two novel uncoupling proteins, are important regulators of energy expenditure and thermogenesis in various organisms. The striking disparity between UCP2 mRNA and protein levels in muscle tissues prompted initial speculation that microRNAs are implicated in the regulatory pathway of UCP2. We found, for the first time, that the repression of UCP2 expression in cardiac and skeletal...
We investigate the effects of continuous human growth hormone (GH) therapy in young obese mice on thermogenesis. Female KK-A y obese mice (n=10) were injected subcutaneously with GH (3.5 mg/kg/day) for 30 days from 42 days old. As a control, physiological saline was administered (n=10). At the terminal point (71 days old), GH administration affected linear growth, and the Lee obesity index (3 s...
Human UCP2 and UCP3, expressed in yeast, were studied to establish their high affinity regulatory ligands. UCPn were reconstituted into liposomes and assayed for fatty acid (FA)-induced H efflux. All natural long chain FAs activated UCP2and UCP3-mediated H translocation. Coenzyme Q10 had no further significant activating effect. Evaluated parameters of FA activation (FA cycling) kinetics reveal...
Nesfatin-1, an 82 amino acid gastric peptide, is involved in regulation of food uptake and in multiple metabolic activities. Whether nesfatin-1 modulates the differentiation and lipid metabolism of brown adipocytes remains unknown. In the present study, we found that nesfatin-1 mRNA and protein were detectable in isolated brown adipocytes and gradually decreased during differentiation (95% CI 0...
early in the development of many animals, before transcription begins, any change in the pattern of protein synthesis is attributed to a change in the translational activity or stability of mrna in the egg and early embryo. as a result, translational control is critical for a variety of developmental decisions, including oocyte maturation and initiation of preimplantation development. in this s...
OBJECTIVES To examine the in vivo effects of highly active antiretroviral therapy (HAART) regimens on adipose tissue mitochondrial DNA (mtDNA) depletion, mitochondrial organellar proliferation, and markers of adipocyte differentiation and phenotype. DESIGN AND METHODS DNA and mRNA quantification using real-time PCR methods was performed on adipose tissue samples from 31 HIV-infected individua...
The primary aim of this study was to examine the effects of 48-h food deprivation on rat skeletal muscle fiber type, according to myosin heavy-chain (MyHC) isoform composition and some metabolism-related factors in both slow-type dominant and fast-type dominant muscle tissues. Male Wistar rats (7 wk old) were treated with 48-h food deprivation or ad libitum feeding as control. After the treatme...
