Doses of Quercetin in the Range of Serum Concentrations Exert Delipidating Effects in 3T3-L1 Preadipocytes by Acting on Different Stages of Adipogenesis, but Not in Mature Adipocytes

Figure 1

Effects of 1 and 10 μM of quercetin (Q1 and Q10) on gene expression of CEBPβ, CEBPα, PPARγ, SREBF1c, and LPL (a) and on protein expression of PPARγ₁, PPARγ₂, and SREBP1 (b) in 3T3-L1 maturing preadipocytes treated from day 0 to day 8. Values are means ± SEM. Comparisons between each treatment and the controls were analyzed by Student’s -test. The asterisks represent differences versus the controls (; ).
