IGFBP2 and neoplasm: Immunohistochemistry (IHC) staining in tumor sections from mouse models constructed by injecting mice with AsPc-1 cells transfected with IGFBP2-expression plasmids showed a positive correlation of IGFBP2 expression with nuclear p65 (p < 0.001) and vimentin (p < 0.001) expression and an inverse correlation with E-cadherin expression (p < 0.001).
