Establishment and characterization of novel patient-derived extraskeletal osteosarcoma cell line NCC-ESOS1-C1

In conclusion, we established and characterized a novel ESOS cell line, NCC-ESOS1-C1. This cell line will be a useful resource for basic research and preclinical studies.

Publication date: Available online 16 November 2019Source: Materials Chemistry and PhysicsAuthor(s): M. Ramadas, Khalil Ei Mabrouk, A.M. BallamuruganAbstractThree-dimensional (3D) porous apatite (HAP) scaffold has recently emerging as functional biomaterials in bone tissue engineering and wound healing. Here we present a study of the preparation of apatite (HAP) scaffold by gel-casting technique. The scaffold prepared as engineering constructs with non-uniform porosity and interconnected pores with a micro size of 2  μm–2.4 μm range. The resultant scaffolds were characterized in terms of crystalline phase...

Sook Kim Chang-Bae Kong Osteosarcoma (OS) originates from osteoid bone tissues and is prone to metastasis, resulting in a high mortality rate. Although several treatments are available for OS, an effective cure does not exist for most patients with advanced OS. Zoledronic acid (ZOL) is a third-generation bisphosphonate that inhibits osteoclast-mediated bone resorption and has shown efficacy in treating bone metastases in patients with various types of solid tumors. Here, we sought to clarify the mechanisms through which ZOL inhibits OS cell proliferation. ZOL treatment inhibited OS cell proliferation, viability, and ...

Authors: Gang W, Tanjun W, Yong H, Jiajun Q, Yi Z, Hao H Abstract Osteosarcoma (OS) is the most common primary bone tumor that affects adolescents and young adults. Disruption of microRNA (miRNA) regulation is well established in the pathophysiology of different cancers, including OS. Increased expression of miR-9 in OS positively correlates with the tumor size, clinical stage, and distant metastasis. In the present study, we used two different OS cell lines, MG-63 and Saos-2, as in vitro models. Small interfering RNA against miR-9 and miR-9 mimics were used to study the function of miR-9 in these two cell lines. W...

Osteosarcoma (OS) is the most common primary bone malignancy and is a leading cause of cancer-related death in children and young adults. Combination chemotherapy developed 3 decades ago significantly improved long-term survival compared to surgery alone. However, despite notable tumor cytoreduction and remission, the 5-year survival rate has remained static at ∼70% since, and the surviving patients have high chemoresistance with sustained risk of recurrent OS that has propensity to metastasize. After metastasis, the 5-year survival rate is abysmally low (∼10% to 20%). Emerging new evidence has revealed that within...

Osteosarcoma is an aggressive bone cancer that frequently metastasizes to the lungs. The cytotoxicity of most chemotherapeutics and targeted drugs in the treatment of osteosarcoma is partially lessened. Furthermore, there is a poor response to current chemo- and radiotherapy for both primary lesions and pulmonary metastases of osteosarcoma. There is a clear need to explore promising drug candidates that could improve the efficacy of osteosarcoma treatment. Autophagy, a dynamic and highly conserved catabolic process, has dual roles in promoting cell survival as well as cell death. The role of autophagy has been investigated...

Abstract Over the last two decades, there have been no significant changes in patient outcomes in relation to the treatment of osteosarcoma, an aggressive malignant neoplasm. It is known that vascular endothelial growth factor-A (VEGF-A) plays a crucial role in angiogenesis and in osteosarcoma. Moreover, VEGF-A expression correlates with clinical stages of osteosarcoma. The adipokine resistin exhibits proinflammatory, proangiogenic and metastatic properties, and evidence suggests that resistin may serve as a prognostic biomarker linking obesity and inflammation to cancer. However, whether resistin has a role in os...

In conclusion, LHX2 regulates tumorigenesis and autophagy via mTOR in OS and is negatively regulated by miR-129-5p. Targeting the miR-129-5p/LHX2/mTOR axis therefore represents a novel therapeutic strategy for OS treatment. PMID: 31724536 [PubMed - as supplied by publisher]
