IL-6 and PAI-1 are highly co-expressed in EOC samples. (a) Immunohistochemistry for EGFR, IL-6 and PAI-1 in a primary formalin-fixed, paraffin-embedded EOC sample (characteristics reported in Supplementary Table 1). Representative images from sample no. 22 are shown. (b) IL-6, PAI-1 and IL-8 quantification by ELISA in 23 ascites samples from the same EOC patients. (c) Correlation between IL-6 and PAI-1 levels measured in ascites. The linear regression line, Spearman correlations and P-values are shown.
