This study establishes a cell line from prostate tumour tissue derived from the Pten−/−/trp53−/− mouse, termed DVL3 which when subcutaneously implanted in immunocompetent C57BL/6 mice, forms tumours with distinct glandular morphology, strong cytokeratin 8 and androgen receptor expression, recapitulating high-risk localised human PCa. The gene discussed is KRT8; the disease is prostate neoplasm.
