Roles of acetyl-CoA carboxylase beta in muscle cell differentiation and in mitochondrial fatty acid oxidation
1Department of Biochemistry, Purdue University, West Lafayette, Indiana, 47907, USA.
Abstract:
Acetyl-CoA carboxylase beta is expressed primarily in heart and skeletal muscle, where it may play a role in the control of mitochondrial fatty acid uptake and oxidation by controlling carnitine-palmitoyl-CoA transferase 1. To investigate the relationship between ACC-beta expression and myoblast differentiation, we specifically blocked ACC-beta production by expressing an antisense gene to the specific N-terminal region of ACC-beta in H9c2 cells. The expression of the antisense ACC-beta mRNA retarded cell fusion, myosin formation, and creatine kinase induction; all of these parameters are hallmarks of muscle cell differentiation. On the other hand, the rate of fatty acid oxidation was not affected by the presence or absence of ACC-beta in the cells.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
