| Outline of Final Research Achievements |
High mobility group box 2 (HMGB2), which belongs the HMG protein families, was up-regulated in prostate adenocarcinoma compared to normal epithelium. In this study, we investigated functions of HMGB2 for progression, androgen regulation and cell proliferation of hormone naive and castration resistant prostate cancer.
In prostatectomy samples, HMGB2 expression was correlated with Gleason grading and tumor stage, but was not related with overall survival. Compared to hormone naive prostate cancer, HMGB2 expression in hormone-treated prostate cancer tended to be decreased, and was reverse correlated with therapeutic effect.
In prostate cancer cell lines, HMGB2 regulated androgen receptor-mediated pathway in androgen dependent cell line, LNCaP. HMGB2 also regulated cell proliferation in both androgen dependent and independent cancer cell lines.
