Degradation of extracellular matrix such as type II collagen and aggrecan induced by proinflammatory cytokines has been considered as an important hallmark of Osteoarthritis (OA). Roxatidine is a licensed specific competitive H (2) -receptor antagonist used for the treatment of gastric and duodenal ulcers. The pharmacological function of roxatidine on Osteoarthritis (OA) remains unknown. In the current study, we report that roxatidine attenuated TNF-α- induced degradation of type II collagen by suppressing the expression of MMP-3 and MMP-13 in human chondrosarcoma cell line SW1353 cells...

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 μM each compound in a panel of pre-approved drugs. We found that fluoxetine, an antidepressant in the class of selective serotonin reuptake inhibitors (SSRI), down-regulated Wnt/β-catenin signaling in human chondrosarcoma cells...

Clear cell chondrosarcoma is a rare chondrosarcoma variant often involving the long bone epiphyses of young to middle aged adults. We report herein a case involving the left femoral head in a 25-year-old female with a 3-month history of worsening left hip pain. Radiographs revealed a complex, multifocal and lytic lesion centered in the left proximal femoral epiphysis with involvement of the femoral neck. Computed tomography-guided fine needle aspiration biopsy with concomitant core needle biopsy was performed, and a diagnosis of clear cell chondrosarcoma was rendered...

The iliac vein is an extremely rare site for mesenchymal chondrosarcoma, and patients with primary extraskeletal mesenchymal chondrosarcoma arising from a vein always suffer a very poor prognosis. We report a case of a 45-year-old female who presented with a 5-month history of left leg edema in 2015. Contrast-enhanced computed tomography showed a large mass in the left iliac vein with scattered calcifications. Wide-margin resection was performed, and histopathologic and immunohistochemical analyses confirmed the presence of intraluminal mesenchymal chondrosarcoma with local invasion out of the vein wall...

Chondrosarcoma is considered as a common primary bone sarcoma. These sarcomas can form large masses without any specific symptoms because there are no barriers in pelvic anatomy to prevent the enlargement of tumors, and can mimic ovarian masses. We present a pelvic chondrosarcoma in a woman aged 37 years who was misdiagnosed as having an ovarian mass due to the limited information obtained from imaging studies. Pelvic chondrosarcoma should be considered in patients who have pelvic masses with solid components...

Background Soft-tissue chondroma (STC) is a rare benign soft tissue tumor that arises primarily in acral extra-skeletal locations. Occasionally, STCs may arise in more proximal non-acral locations, accompanied by non-classic features that label them as indeterminate lesions and pose diagnostic challenge for both radiologists and pathologists alike. Purpose To explicate the potential of diagnostic imaging in the identification and characterization of appendicular non-acral STCs with emphasis on their morphologic magnetic resonance imaging (MRI) enhancement...

Bone sarcomas are rare, highly malignant mesenchymal tumours that affect teenagers and young adults, as well as older patients. Despite intensive, multimodal therapy, patients with bone sarcomas have poor 5-year survival, close to 50%, with lack of improvement over recent decades. TNF-related apoptosis-inducing ligand (TRAIL), a member of the tumour necrosis factor (TNF) ligand superfamily (TNFLSF), has been found to induce apoptosis in cancer cells while sparing nontransformed cells, and may therefore offer a promising new approach to treatment...

BACKGROUND: Extraskeletal mesenchymal chondrosarcoma (ESMCS) is an unusual pathologic variant of chondrosarcoma. There are no specific clinicoradiographic parameters to distinguish it from other intracranial pathologies. The diagnosis can be established only on the basis of histopathology, which may pose significant challenges in certain unusual locations. PURPOSE: In this case, we discuss the pitfalls in diagnosis, management, and major characteristics of ESMCS with a review of current literature...

The cell-based therapies could be potential methods to treat damaged cartilage tissues. Instead of native hyaline cartilage, the current therapies generate mainly weaker fibrocartilage-type of repair tissue. A correct microenvironment influences the cellular phenotype, and together with external factors it can be used, e.g., to aid the differentiation of mesenchymal stem cells to defined types of differentiated adult cells. In this study, we investigated the effect of long-term exposure to 5% low oxygen atmosphere on human chondrosarcoma HCS-2/8 cells...

Nicotinamide phosphoribosyltransferase (NAMPT) and nicotinic acid phosphoribosyltransferase (NAPRT) are rate-limiting enzymes in the nicotinamide adenine dinucleotide (NAD+) synthesis pathway. Chondrosarcoma is a malignant cartilage forming bone tumor, in which mutations altering isocitrate dehydrogenase-1 and -2 (IDH1 and IDH2) activity have been identified as potential driver mutations. Vulnerability for NAD+ depletion has been reported for IDH1/2 mutant cells. Here, the potency of NAMPT inhibitors as a treatment of chondrosarcoma was explored...

The content of components of the RANK/RANKL/OPG system, the key regulator of homeostasis in the bone tissue, in blood serum samples from 199 patients with primary bone neoplasms and 131 practically healthy volunteers was measured by ELISA. Borderline giantcell tumor of the bone with high osteoclastogenic and osteolytic activity is characterized by an increase in the level of all components of this system and highest ratio of sRANKL/OPG in the blood serum. Study indexes in patients with various benign neoplasms and tumor-like bone lesions were lower than in patients with giant-cell tumor...

Chondrosarcoma is the most common bone sarcoma in adults. Conventional chondrosarcoma, the commonest histological subtype, is largely resistant to anthracycline-based chemotherapy. There have been anecdotal reports of durable clinical benefit with antiangiogenic agents in this disease. A retrospective search of patients treated at three sarcoma referral centers was performed to identify patients with advanced chondrosarcoma treated with antiangiogenic agents. The aim of this study was to evaluate the efficacy and safety of antiangiogenic agents in advanced chondrosarcoma...

Conventional chondrosarcoma is the most common primary bone tumor in adults. Prognosis corresponds with tumor grade but remains variable, especially for individuals with grade (G) II disease. There are currently no biomarkers available for monitoring or prognostication of chondrosarcoma. Circulating tumor DNA (ctDNA) has recently emerged as a promising biomarker for a broad range of tumor types. To date, little has been done to study the presence of ctDNA and its potential utility in the management of sarcomas, including chondrosarcoma...
