Mamals have two major isoforms of acetyl-CoA β-form (ACβ) is predominantly in heart and skeletal muscle while the 265 kDa α-form (ACCα) is the major isoform in lipogenic tisues such as liver and adipose tisue. ACCβ is thought to control faty acid oxidation by means of the ability of malonyl-CoA to inhibit carnitine palmitoyl-CoA transferase-1 (CPT-1), which is a rate-limiting enzyme of fatty acid oxidation in mitochondria. Previously, it was reported that MyoD and other muscle regulating β by interactions betwen these factors and several cis-elements of ACβ promoter. We described here that ACCβ expression mediated by MRFs is regulated by retinoic acids. Endogenous expres-sion of ACβ in diferentiated H9C2 myotube was significantly increased by retinoic acid treatment. However, on transient transfection assay in H9C2 myoblast, ACβ promoter activity was suppresed by RXRα and more severely by RARα. These ef-fects on ACβtubes by RXRα and RARα seem to be mediated by their interactions with MRFs because no con-sensus sequence for RXRα and RARα has been found in ACβ promoter and retinoic acid recep-tors did not affect this promoter activities by itself. In transient transfection in NIH3T3 fibroblast, the activation of ACβ promoter by MyoD, main MRF in myoblast, was significantly suppressed by RARα and to a less extent by RXRα while the RXRα drastically augmented the activation by MRF4, ma-jor MRF in myotube. These results explained that retinoic acids diferentially affected the action of MRFs according to their types and RXRα specially elevates the expression of muscle specific genes by stimulating the action of MRF4.
