STAT1 expression in tumor vs. tumor free adjacent tissue and in different areas of the same tumor. (A) mRNA expression levels of STAT1 and the STAT1 target gene IRF1 in tumor areas and matched tumor-free adjacent tissue were determined in 15 pairs of tissue. Statistical significance was determined with paired Student’s T-test. (B) Example for a tumor with strong and weak staining for STAT1 in neighboring regions.
