Combined loss of Eaf2 and Ell2 induced murine prostatic intraepithelial neoplasia in the mouse model. A. Histology of mouse ventral prostate from wild-type (Eaf2+/+Ell2+/+PbsnCre4), Eaf2+/- (Eaf2+/-Ell2+/+PbsnCre4), Ell2-cko (Eaf2+/+Ell2-/-PbsnCre4), and Eaf2+/-Ell2+/- (Eaf2+/-Ell2loxp/+PbsnCre4) C57BL/6J male mice aged 24 months stained with hematoxylin and eosin (H&E). Original magnification, × 10, inset, × 40. B. Quantification of mPIN incidence in mice. Data are expressed as percentage from 3 to 6 mice per group. *P < 0.05.
