Does tUSC5 regulate insulin-mediated adipose tissue glucose uptake by modulation of GLUT4 recycling?
Collectively, these findings establish TUSC5 as an adipose tissue-specific protein that enables proper protein recycling, linking the ubiquitous vesicle traffic machinery with tissue-specific insulin-mediated glucose uptake into adipose tissue and the maintenance of a healthy metabolic phenotype in mice and humans.
Moderate and intense exercise were effective in attenuating PPL in both ɛ2 and ɛ3 subjects, with ɛ2 subjects being more susceptible to the lipid lowering effect of moderate training than ɛ3 subjects. Carriers of the ɛ4 allele, however, showed no attenuation of postprandial lipemia.
