The effects of folic acid (5.7 and 71 microg/kg), 4 weeks) consumption on the beta-adrenoceptors (beta-ARs)-elicited lipolysis in vitro of the abdominal adipocytes of the lean/control (+m/+db) and obese/diabetic (+db/+db) mice (female) were investigated. beta-AR agonists (salbutamol, a beta2-AR agonist; BRL 37344 and CGP 12177, beta3-AR agonists; adrenaline, a beta-AR agonist)-mediated lipolysis, beta2 and beta3-ARs protein expression of the adipose tissues after folic acid consumption were evaluated. Our results demonstrate that a smaller magnitude of the basal (spontaneous) and the beta-AR agonists-triggered lipolysis was observed in +db/+db mice, and folic acid supplementation (71 microg/kg) resulted in an improvement of both the baseline and the beta-ARs-mediated lipolysis. In controls, a lower beta2 and beta3-ARs protein expression of the adipose tissues was detected in +db/+db mice, compared to +m/+db mice. In both strains fed with folic acid (71 microg/kg), a reduction of beta2-AR protein expression was observed compared to the respective controls. In +db/+db mice, folic acid (5.7 and 71 microg/kg) consumption caused a dose-dependent increase of beta3-AR protein expression compared to controls. We demonstrate that lipolysis elicited by beta-AR (beta2- and beta3-ARs) agonists was blunted in +db/+db mice. Folic acid consumption has significant modulatory effects on beta-ARs protein expression and lipolysis.
