| Outline of Final Research Achievements |
Novel NFκB inhibitors showed significant cytotoxicity on our cell lines derived from bladder cancer (BC), renal cell cancer (RCC) and prostate cancer (PC). Although some compounds failed to show a significant induction of apoptosis in PC cells, newly developed compounds showed significant cytotoxic effects on DU145 and PC3 cells. The expression of legumain was confirmed at the mRNA and protein levels in our PC cell lines. The immunochemical-staining patterns of legumain in prostatectomy specimens were significantly associated with unfavorable pathology and prognosis. However, hypoxia and so on did not regulate the expression of legumain. Sarcopenia, NLR and CRP were significantly associated with prognosis in patients with invasive BC, CRPC and advanced RCC and pyuria was an independent prognostic factor for intravesical recurrence in patients with superficial BC, which suggest that inflammatory immune response may play a key role in the disease progression in urological malignancies.
