Basal levels of (A) C/EBP-α, (B) GLUT4, (C) S100B, (D) PPAR-α, (E) PPAR-β/δ, (F) PPAR-γ, (G) TSPO, (H) PKCε mRNAs normalized to RPS18.

Cells were seeded and collected after the indicated time points; day 0 represents one day after the plating. Results are expressed in terms of mean and S.E.M., calculated from 3 independent experiments and presented as fold increase or decrease from the value measured on day 0. Significance (compared to day 0 values) was calculated using one-way ANOVA followed by Bonferroni's post hoc test; *p<0.05, **p<0.01, ***p<0.001.
