Rb1 decreased the lipid storage inside differentiated 3 T3-L1 adipocytes. a Representative oil red O staining of adipocytes with or without Rb1 treatment in the presence or absence of GW9662. Scale bar: 50 μm. b Quantification of the TG concentration, c leptin levels and d adiponectin expression levels in the cell culture medium. e Representative western blot analysis and f quantification of AQP7, g pPPARγ, h PPARγ and i pPPARγ/PPARγ in vitro. *p < 0.05, the Rb1 group compared with the control group; **p < 0.01, the Rb1 group compared with the control group; ^#p < 0.05, the GW9662 + Rb1 group compared with the Rb1 group; ^##p < 0.01, the GW9662 + Rb1 group compared with the Rb1 group
