Effects of FAs on mRNA expression of D9D/SCD1. Cells were differentiated in the presence of 100 μM FA or vehicle control. EPA, in contrast to STA and OLA, resulted in a significant inhibition of D9D/SCD1 gene expression. All values are means ± SEM of percent gene expression relative to CTRL, where cDNA levels were normalised by cyclophilin levels (n = 4). Values with different superscript letters are significantly different at P < 0.05 by Tukey's post hoc test.
