However, activation of the “floxed” human AR transgene (hARtg) expression in a subpopulation of prostatic progenitors through the Osr1 (odd skipped related1) promoter-driven Cre recombinases developed high-grade prostatic intraepithelial neoplasia (HGPIN) and invasive prostatic adenocarcinoma (PCa) lesions in mice10. The gene discussed is AR; the disease is posterior cortical atrophy.
