PELP1 expression in human normal–inflammation–tumor spectra.A–E, left, statistical analysis of IHC staining of PELP1 in normal–inflammation–tumor progression models of gastric, colon, breast, cervix, and prostate cancer disease spectra showing higher PELP1 positivity in a progressive manner from normal to cancer. The histograms represent mean Q score of PELP1 expression in normal, inflammation, and cancer specimens of respective tissues. Right, representative images of normal–inflammation–tumor progression models of gastric, colon, breast, cervix, and prostate cancer disease spectra. IHC, immunohistochemistry; PELP1, proline, glutamic acid, and leucine-rich protein 1.
