The GLUT4 gene is subject to complex tissue-specific and metabolic regulation, with a profound impact on insulin-mediated glucose disposal. We have shown, by using transgenic mice, that the human GLUT4 promoter is regulated through the cooperative function of two distinct regulatory elements, domain 1 and the myocyte enhancer factor 2 (MEF2) domain. The MEF2 domain binds transcription factors M...
The myocyte-specific enhancer-binding factor MEF-2 is a nuclear factor that interacts with a conserved element in the muscle creatine kinase and myosin light-chain 1/3 enhancers (L. A. Gossett, D. J. Kelvin, E. A. Sternberg, and E. N. Olson, Mol. Cell. Biol. 9:5022-5033, 1989). We show in this study that MEF-2 is regulated by the myogenic regulatory factor myogenin and that mitogenic signals bl...
Reduced quadriceps endurance in chronic obstructive pulmonary disease (COPD) is associated with a predominance of type II glycolytic fibres over type I oxidative fibres (fibre shift) and reduced muscle energy stores. The molecular mechanisms responsible for this remain unknown. We hypothesised that expression of known regulators of type I fibres and energy production in quadriceps muscle would ...
Calcium signaling is critical for activation of T lymphocytes and has been proposed to be transduced through multiple calmodulin target proteins. Whereas the calcineurin-NFAT signaling module is critical for all mammalian T cells, the role of calmodulin-dependent kinase IV (CaMKIV) in mouse naïve CD4+ T-cell activation remains enigmatic. We have applied lentivius-mediated RNA interference of Ca...
