| Outline of Final Research Achievements |
The aim of the study was to elucidate the signal crosstalk in prostate cancer xenograft model, JDCaP. JDCaP expressed typical markers of prostate cancer such as PSA, AR and ERG. Several pathways including AR and tyrosine kinase-akt were activated in JDCaP. IN vivo xenograft model, both anti-androgen drug, bicalutamide and throsine kinase inhibitor, sunitinib showed anti-tumor effect. However, sunitinib inhibited tyrosine kinase pathway but activated AR pathway, which suggested signal crosstalk of both pathways.
