Two human pancreatic tissue cohorts were used in this study. The expression of UTX was analyzed in cohort #1 with 84 primary PDA, 84 adjacent pancreatic intraepithelial neoplasia (PanIN), and normal pancreatic tissue specimens (US Biomax). Correlation analysis of GATA6 and UTX protein expression was performed using cohort #2 with 60 PDA tissues. Immunohistochemical analyses of these specimens and xenografts were conducted with anti-GATA6 (R&D), anti-UTX (Bethyl Laboratories), and anti-Ki67 (Santa Cruz Biotechnology) antibodies as described previously.20 (link), 21 (link), 22 (link), 23 (link)
