  • This study showed that adrenaline or isoproterenol increased the release of LPL activity in the plasma and the incubation medium, and it discussed the possible mechanism by which catecholamines exert this effect.

  • Lowell BB, et al.

  • This effect could not be explained by changes in PER2 expression, since the Per2 gene was shown to control lipid metabolism by repressing PPARG in mice [29] and we found no difference in PER2 expression between lean and obese during the 24 h period. Comparison among clock genes between lean and obese were analyzed using Student's t test.
