From: Epigenetic modifying enzyme expression in asthmatic airway epithelial cells and fibroblasts
Principal component analysis (PCA) of epigenetic modifier enzymes in airway epithelial cells (AECs) and airway fibroblasts. Gene expression levels of 82 genes were used to construct the PCA plot. Healthy samples are identified with a triangle, asthmatic samples with a circle. Filled symbols indicate male samples whereas open symbols indicate female samples. AECs are shown in black and airway fibroblasts (Fb) are shown in blue
