Expression of HIF1α target genes. HIF1α target genes and their expression levels after 3 d of exposure of HaCaT cells to 30 μg/ml WC and 33 μg/ml WC-Co nanoparticles and 3 μg/ml CoCl2. Bars indicate the mean microarray expression levels of 5 biological replicates. This figure represents all affected HIF target genes identified as significantly differentially expressed by SAM without a fold change threshold.
