Fluorescent labeled osteosarcoma cell line was transplanted in nude mice and harvested in lung metastasis to obtain higher metastatic cell line. The more metastatic potential, the more PAI -1 and u-PA levels increased. We previously reported that caffeine-assisted chemotherapy. We found caffeine affects tumor cells through various pathways, such as PTEN, AKT, NF-kB, and ERK activities. Modulation of cisplatinum efficacy induced by caffeine was visualized at the subcellular level by fluorescent ubiquitination-based cell cycle indicator in the nucleus. Caffeine overcame the cell-cycle arrest induced by cisplatinum, thereby increasing its efficacy. Theobromine, a caffeine derivative, was investigated as a new anti-cancer effect. It elevates intracellular cAMP levels and inhibits cell proliferation. Surgical navigation for bone and soft tissue tumor in mouse and human was also performed using ICG and near-infrared fluorescent imaging.
