A, Transcription level of the adipogenic genes in baicalein-treated cells. 3T3-L1 cells (undifferentiated cells: U; white columns) were differentiated into adipocytes (differentiated cells: D) for 6 days in DMEM in the absence (gray columns) or presence of baicalein (50 μM; black columns). Data are the means ± S.D. from three experiments. **p<0.01, as indicated by the brackets. B, Expression level of the lipogenic genes in baicalein-treated 3T3-L1 cells. Cells were differentiated into adipocytes as described in the legend of Fig 2A. Data are the means ± S.D. from three experiments. **p<0.01, as indicated by the brackets. C, Messenger RNA level of the lipolytic genes in baicalein-treated cells. 3T3-L1 cells were differentiated into adipocytes as described in the legend of Fig 2A. Data are the means ± S.D. from three experiments. **p<0.01, as indicated by the brackets. D, Change in glycerol level in baicalein-treated 3T3-L1 cells. Cells were differentiated into adipocytes as described in Materials and Methods. Data are the means ± S.D. from three experiments. **p<0.01, as indicated by the brackets.
