MicroRNAs (miRNAs) have emerged as potential anticancer agents, but their clinical application is limited by the lack of an effective delivery system to tumors. Exosomes are small vesicles that play important roles in intercellular communication. Here, we show that synthetic miR-143 introduced into cells is released enveloped in exosomes and that the(More)
BACKGROUND One of the major components of telomerase is the human telomerase reverse transcriptase (hTERT) as the catalytic protein. hTERT mRNA expression are reported to be associated with prognosis and tumor progression in several sarcomas. However, there is no clear understanding of the mechanisms of hTERT in human sarcomas. Recent studies have suggested(More)
PURPOSE We recently reported the sarcoma-selective antitumor effects of a newly developed nitrogen-containing bisphosphonate, minodronate (MIN), on malignant bone tumors. The aim of this study was to develop efficient combination MIN therapy in malignant bone tumors. METHODS We examined downstream molecular events of MIN in osteosarcoma and Ewing's(More)
SS18-SSX (formerly called SYT-SSX) fusion gene has been established clinically as a molecular diagnostic test for synovial sarcoma, but the prognostic value of the fusion gene variant for survival is controversial. The objective of this systematic review is to provide an up-to-date and unprecedented summary of the prognostic impact of SS18-SSX fusion type(More)
BACKGROUND The function of promyelocytic leukemia (PML) bodies is not well known but plays an important role in controlling cell proliferation, apoptosis and senescence. This study was undertaken to analyze the clinical significance of PML body expression in primary tumor samples from malignant fibrous histiocytoma (MFH) and liposarcoma patients. METHODS(More)
BACKGROUND Brachytherapy, interstitial tumor bed irradiation, following conservative surgery has been shown to provide excellent local control and limb preservation in patients with soft tissue sarcomas (STS), whereas little is known about the tolerance of peripheral nerves to brachytherapy. In particular, nerve tolerance to high-dose-rate (HDR)(More)
Liposarcoma is categorized as a soft tissue sarcoma and most commonly appears in the lower extremities and rarely in the foot during adulthood. We present a very rare case report of a primary well-differentiated liposarcoma arising in the foot on a 60-year-old female. Marginal resection of the tumor with metatarsal ray amputation was eventually performed.(More)
