Induction of differentiation and apoptosis in cancer cells by ligands of PPARgamma is a novel therapeutic approach to malignant tumors. Chondrosarcoma (malignant cartilage tumor) and OUMS-27 cells (cell line established from grade III human chondrosarcoma) express PPARgamma. PPARgamma ligands inhibited cell proliferation in a dose-dependent manner, and induced apoptosis of OUMS-27. The higher-g...

Chondrosarcoma is a highly malignant cartilage-forming bone tumor that has the capacity to invade locally and cause distant metastasis. Moreover, chondrosarcoma is intrinsically resistant to conventional chemotherapy or radiotherapy. The novel benzofuran derivative, BL-038 (2-amino-3-(2,6-dichlorophenyl)-6-(4-methoxyphenyl)benzofuran-4-yl acetate), has been evaluated for its anticancer effects ...

INTRODUCTION Cartilaginous tumors involving the small bones of the hands and feet are usually benign such as enchondroma, chondromyxoid fibroma and chondroblastoma. The small bones of the hands and feet are rarely involved by primary chondrosarcoma. Proximal phalanges are the most common sites in the hands, but the fourth digit is the least common site. CASE PRESENTATION We report a case of a...

Chondrosarcoma is a primary malignant bone cancer, with a potent capacity to invade locally and cause distant metastasis; it has a poor prognosis and shows a predilection for metastasis to the lungs. Brain derived neurotrophic factor (BDNF) is a small-molecule protein from the neurotrophin family of growth factors that is associated with the disease status and outcomes of cancers. However, the ...

PURPOSE Chondrosarcomas are notoriously resistant to cytotoxic chemotherapeutic agents. We sought to identify critical signaling pathways that contribute to their survival and proliferation, and which may provide potential targets for rational therapeutic interventions. EXPERIMENTAL DESIGN Activation of receptor tyrosine kinases (RTK) was surveyed using phospho-RTK arrays. S6 phosphorylation ...

Introduction Myxoid chondrosarcoma is a distinct subtype of chondrosarcoma with several key differences from conventional chondrosarcoma of bone. Our review of the literature and have found that myxoid chondrosarcoma is typically extra skeletal in presentation. Very few cases of myxoid chondrosarcoma of the hand or wrist have been reported and they were extra skeletal in presentation [1-10]. We...

Intracranial chondrosarcoma is a very rare malignant tumor of the central nervous system, and is difficult to preoperatively distinguish from other tumors using conventional imaging techniques. Here, we report the case of a 24-year-old woman who presented with mild headache due to chondrosarcoma in the frontal lobe. Preoperative conventional images showed findings typical of an oligodendroglial...

Abnormal activation of the Wnt/β-catenin signaling is implicated in the osteoarthritis (OA) pathology. We searched for a pre-approved drug that suppresses abnormally activated Wnt/β-catenin signaling and has a potency to reduce joint pathology in OA. We introduced the TOPFlash reporter plasmid into HCS-2/8 human chondrosarcoma cells to estimate the Wnt/β-catenin activity in the presence of 10 μ...

BACKGROUND: Malignant neoplasms with lesions of the chest are quite rare in sternum and range from 0.5 to 3.1% total number patients bone tumors all localizations. In this connection, there few publications describing tactics surgical treatment methods prosthetics formed defect. The present article describes a clinical case successful application an individual prosthesis manubrium G1 chondrosar...
