(A) Phosphorylation of signal transducer and activator of transcription 1 (pSTAT1) in the intestinal mucosa from patients with ulcerative colitis (UC) or Crohn's disease (CD) and normal controls (N). STAT1 phosphorylation was expressed as the ratio of pSTAT1 to total STAT1. Every membrane was probed with an anti-PY701-STAT1 antibody and afterwards reprobed with a STAT1 specific antibody (an example is shown in (B)).
