T10c12 Conjugated Linoleic Acid Causes Delipidation In 3t3-L1 Adipocytes And Mice, Shan Jiang Apr 2010

T10c12 Conjugated Linoleic Acid Causes Delipidation In 3t3-L1 Adipocytes And Mice, Shan Jiang

Department of Animal Science: Dissertations, Theses, and Student Research

T10c12 conjugated linoleic acid (t10c12 CLA) causes the reduction of triglyceride contents in adipocytes. T10c12 CLA’s delipidation effect is associated with decreased nutrient uptake, adipogenesis, lipogenesis, and increased energy expenditure, lipolysis, fatty acid oxidation in adipocytes. However, the molecular mechanisms of CLA’s delipidation effects are still unknown. AMP-activated protein kinase (AMPK), a central regulator of cellular energy levels, is activated by an increase in the cellular AMP:ATP ratio or various cellular stresses. We demonstrated that t10c12 CLA activated AMPK in 3T3-L1 adipocytes, leading to inhibition of anabolic biosynthesis and increase of energy expenditure. Strong activation of AMPK can induce an …

The aim of our project was to study the effect of streptozotocin (STZ)—induced hyperglycemia on sciatic nerve morphology, blood plasma markers and immunohistochemical expression of RAGE (the Receptor for Advanced Glycation End-products), and its ligands—S100B and Carboxymethyl Lysine (CML)-advanced glycation endproduct (AGE) in the laboratory pig. Six months after STZ—injections, blood plasma measurements, morphometric analysis of sciatic nerve fiber density, immunofluorescent distribution of potential molecular neuropathy contributors, ELISA measurement of plasma AGE level and HPLC analysis of sciatic nerve levels of one of the pre-AGE and the glycolysis intermediate products—methyl-glyoxal (MG) were performed. The results of our study revealed that …
