Tyrosine phosphorylation of STAT1 in inflamed whole tissue extracts and specifically in muscularis mucosa. Western blot analyses using equal amounts of protein from whole cell extracts (50 μg) (a) and equal volume of laser-dissected muscularis mucosa extracts (b) from both noninflamed and inflamed area from same patient sample are shown with 701-phospho-specific tyrosine antibody. c: Microscopic picture demonstrated by asterisks that the microdissected cells derived from the muscularis mucosa.
