Plasma concentrations of adiponectin have been shown to be decreased in patients with obesity, cardiovascular diseases, hypertension and metabolic syndrome. Recent studies have found that adiponectin reduces lipid accumulation in macrophage foam cells which may impact the development of atherosclerosis. However, it remains unclear whether adiponectin is(More)
BACKGROUND Carnitine palmitoyltransferase-1 (CPT1) is a rate-limiting step of mitochondrial β-oxidation by controlling the mitochondrial uptake of long-chain acyl-CoAs. The muscle isoform, CPT1b, is the predominant isoform expressed in the heart. It has been suggested that inhibiting CPT1 activity by specific CPT1 inhibitors exerts protective effects(More)
The hormone resistin, which was originally shown to induce insulin resistance, has been implicated in the regulation of inflammatory processes, but the molecular mechanism underlying such regulation has not been clearly defined. The goal of our study was to determine whether the expression of COX-2 can be induced by resistin and what the potential signaling(More)
Adiponectin, an adipocyte-derived hormone, is a versatile player involved in the regulation of energy homeostasis, cardiovascular disease, and diabetes. Within adipocytes, adiponectin is retained in the lumen of the endoplasmic reticulum (ER) by binding to the thiol protein ER resident protein 44 kDa (ERp44), which is apparently regulated by the activation(More)
Mitochondrial function is paramount to energy homeostasis, metabolism, signaling, and apoptosis in cells. Mitochondrial complex V (ATP synthase), a molecular motor, is the ultimate ATP generator and a key determinant of mitochondrial function. ATP synthase catalyzes the final coupling step of oxidative phosphorylation to supply energy in the form of ATP.(More)
The Kruppel-like factors (KLFs) belong to the family of zinc finger-containing transcription factors that regulates a diverse array of cellular processes, including cell proliferation, differentiation, and apoptosis. Here we reported the structure, mapping and phylogenetic analysis of KLF gene family in pigs. Comparative analyses revealed strong(More)
BACKGROUND Carnitine Palmitoyl Transferase 1 (CPT1) is the rate-limiting enzyme governing long-chain fatty acid entry into mitochondria. CPT1 inhibitors have been developed and exhibited beneficial effects against type II diabetes in short-term preclinical animal studies. However, the long-term effects of treatment remain unclear and potential non-specific(More)
Acetyl-CoA carboxylase (ACC; EC 6.4.1.2) is the major enzyme of fatty acid synthesis and oxidation in response to dietary changes. In animals, there are two major isoforms of ACCs, ACC1 and ACC2, which are encoded by different genes and display distinct tissue and cellular distribution. We examined the effect of high concentration of arachidonic acid (AA)(More)
Skeletal muscle formation is controlled by multiple processes. These processes are tightly regulated by muscle regulatory factors. Genes that are highly and specifically expressed during myogenesis need to be identified. In the present study, the role of an anti-adipogenic gene adipose (Adp) in myogenesis is demonstrated. We discover that the expression of(More)
Obesity has become an epidemic health problem characterized by aberrant energy metabolism. As the major player in energy homeostasis, adipose tissue has a decisive role in the development of obesity. Many genes involved in adipogenesis are also correlated with obesity. Adipose (Adp) has been established as an anti-obesity gene to repress adipogenesis and(More)
