Fig. 6. Comparison of gene expression profiles as quantified with the DNA microarray in differentiating 3T3-L1 adipocytes (white) and in 3T3-L1 preadipocytes incubated with 10 nM antimycin A (grey). Cells were differentiated or treated with 10 nM AA for (A) 2, (B) 4, (C) 6 and (D) 8 days; data are presented for some selected genes to illustrate major similarities and differences between both treatments. For the other genes, see Tables 1 and 3. Mean ratios indicate a fold-increase or decrease in gene expression. ^*, significant mean ratios, obtained from ratios falling out of the 95% confidence interval.
