Genes identified as differentially expressed after treatment with high-dose (100 μM) fenofibrate. The plots show upregulation (red) and downregulation (green) of expression compared to DMSO control-treated cells. Cells were treated with 10 μM ("low dose") or 100 μM ("high dose") fenofibrate for 48 hours. Left – Normalised uncorrected data. Right – Data corrected using ICA-based filtering and removal of artefactual components. The data is improved but reveals an aberrant sample in the high-dose group (the first).
