(a) Detection of the phosphorylated form of p38α mitogen-activated protein kinase (MAPK) (phospho-p38α) by immunoblotting in the inflamed mucosa from three patients with ulcerative colitis (UC) and three patients with Crohn's disease (CD), and in the normal mucosa of three healthy controls (HC). Blots were stripped and analysed for p38α. Each example is representative of experiments performed in 12 UC patients, seven CD patients and 18 control subjects. (b) Densitometry of Western blots. Phospho-p38α expression is normalized for p38α. Horizontal bars are mean; a.u.: arbitrary units.
