Currently, there are no preclinical immunocompetent mouse models that adequately represent all stages of prostate cancer (PC) especially, androgen depletion independent (ADI) and bone metastatic PC. The best characterized, Transgenic Adenocarcinoma of the Mouse Prostate (TRAMP) model is logistically a difficult model for in vivo assessments and it does not adequately represent all stages of PC. Therefore, the aim of this study was to broaden the TRAMP model to include ADI and bone metastatic PC. Three ADI sublines were derived from androgen-sensitive (AS) TRAMP C1 (TC1) and TRAMP C2 (TC2) parental lines in vitro by dihydrotestosterone (TC1-T5 and TC2-T5) deprivation and in vivo by growing in TRAMP female mice (TC1-F1). The new sublines showed several characteristic features of ADI-PC 1.) faster growth rates in vitro and in vivo 2.) increased invasiveness 3.) androgen depletion independence in vitro and in vivo 4.) variable expression of androgen receptor 5.) downregulation of metastasis suppressor genes, E-cadherin and KAI-1. Genetic and molecular studies of ADI sublines showed alteration of genes representing major cancer related pathways. ADI TC1-T5, that displayed the most aggressive phenotype/genotype was selected to expand the TRAMP model to represent PC metastases Metastatic ability of TC1-T5 to migrate to bone and other soft tissues after intracardiac injections was shown in contrast to AS TC1 cells. Bone metastatic lesions displayed both osteoblastic and osteolytic features in multiple locations. Additionally, unlike AS TC1, the TC1-T5 tumours were able to grow with 100% incidence in the prostate and as lungs pseudometastases. The ADI PC lines were used to explore Aurora Kinases (AKs) as therapeutic targets for ADI PC. Compared to TC1, ADI-TC1-T5 cells showed a significant upregulation of AK-A and AK-B and their downstream regulators, survivin and phosphorylated-histone H3. Enhanced sensitivity of TC1-T5 to AK inhibitor VX680 functionally validated this and together with docetaxel led to enhanced efficacy which correlated with implication of AK-A/B in development of docetaxel-resistance. Thus, TRAMP model now represents ADI-PC that can grow in the bone, lungs and in the prostate; a significant step towards a well rounded preclinical model with greater clinical relevance.
