Osteosarcoma is the most common primary malignancy of bone, and is a high-grade malignant mesenchymal tumor with high recurrence and metastatic rates. Increased expression of secreted protein, acidic and rich in cysteine (SPARC) indicates poor prognosis in a number of malignances. However, the expression level of SPARC in human osteosarcoma and its associated mechanism remains unclear. To analyze the expression of SPARC in human osteosarcoma and its potential application in the diagnosis and treatment of osteosarcoma, the clinical records and samples of 20 cases of osteosarcoma were collected...

The prognostic role of the C-reactive protein to albumin ratio (CRP/Alb ratio) in patients with osteosarcoma has not been investigated. A total of 216 osteosarcoma patients were enrolled in the study. Univariate and multivariate survival analyses between the groups were performed and Kaplan-Meier analysis was conducted to plot the survival curves. Receiver operating characteristic curves were generated and areas under the curve (AUCs) were compared to assess the discriminatory ability of the inflammation-based indicators, including CRP/Alb ratio, Glasgow prognostic score (GPS), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR)...

mTOR is a valuable oncotarget for osteosarcoma. The anti-osteosarcoma activity by a novel mTOR kinase inhibitor, CZ415, was evaluated. We demonstrated that CZ415 potently inhibited survival and proliferation of known osteosarcoma cell lines (U2OS, MG-63 and SaOs2), and primary human osteosarcoma cells. Further, CZ415 provoked apoptosis and disrupted cell cycle progression in osteosarcoma cells. CZ415 treatment in osteosarcoma cells concurrently blocked mTORC1 and mTORC2 activation. Intriguingly, ERK-MAPK activation could be a major resistance factor of CZ415...

Osteosarcoma is the most common malignant tumour found in bones, and it has a poor prognosis. For improved therapy, it is significant to have a deep understanding of the proteomics changes in the cancer stem cells (CSCs) of osteosarcoma. Therefore, a comparative proteomics approach based on ultra-high-performance liquid chromatography coupled to an Orbitrap Fusion mass spectrometer (UHPLC-Orbitrap Fusion MS) was established to investigate the key molecular changes between CSCs and non-CSCs in human osteosarcoma HOS cells...

Osteosarcoma (OS) is the most common type of malignant bone tumor in children and adolescents. However, the molecular mechanism underlying OS development is unclear. Here, we investigated the contribution of lncRNA-p21, a novel long non-coding RNA, on OS cell proliferation. Our results demonstrated that the expression of lncRNA-p21 was repressed in OS tissue. Growth curves and the cell colony formation assay showed that lncRNA-p21 significantly inhibited the proliferation of OS cell lines. In addition, the expression of lncRNA-p21 increased the protein levels of proliferation markers, such as Ki-67 and cyclin D1...

For the treatment of metastatic bone cancer, local delivery of therapeutic agents is preferred compared to systemic administration. Delivery of an anti-cancer drug and a protein that helps in bone regeneration simultaneously is a challenging approach. In this study, a nanoparticulate carrier which delivers a protein and an anti-cancer drug is reported. Bovine serum albumin (BSA) as a model protein was loaded into hydroxyapatite (HA) nanoparticles (NPs) and methotrexate (MTX) conjugated to poly(vinyl alcohol) was coated onto BSA-loaded HA NPs...

Apoptosis in intestinal epithelial cells (IECs) prevents the development of Crohn's disease (CD), a type of inflammatory bowel disease (IBD). Runt-related transcription factor 2 (Runx2) inhibits apoptosis in osteosarcoma-derived U2OS cells via down-regulating the transcriptional activity of p53. However, the expression and function of Runx2 in CD remain unclear. In this study, Runx2 protein levels were decreased in the intestinal epithelial cells (IECs) of CD patients and in a mouse 2, 4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis model; in contrast, the expression levels of p53 and Bax, a p53-target gene, were increased...

BACKGROUND: The response of conventional chemotherapy for osteosarcoma treatment is usually poor, and chemotherapy-related severe side effects and drug resistance remain a problem. Abundant evidence has shown that Astragaloside IV, extracted from Astragalus membranaceus Bunge, strongly inhibits the growth of many carcinomas. We aimed to investigate the chemosensitive effects of Astragaloside IV in osteosarcoma in vitro and in vivo. METHODS: Human osteosarcoma cell lines MG-63 and 143B, and BALB/c nu/nu mice xenograft were used...

A novel multifunctional nanodevice based in doxorubicin (DOX)-loaded mesoporous silica nanoparticles (MSNs) as nanoplatforms for the assembly of different building blocks has been developed for bone cancer treatment. These building blocks consists of: i) a polyacrylic acid (PAA) capping layer grafted to MSNs via an acid-cleavable acetal linker, to minimize premature cargo release and provide the nanosystem of pH-responsive drug delivery ability; and ii) a targeting ligand, the plant lectin concanavalin A (ConA), able to selectively recognize, bind and internalize owing to certain cell-surface glycans, such as sialic acids (SA), overexpressed in given tumor cells...

Wnt/β-catenin or canonical Wnt signaling pathway regulates the self-renewal of cancer stem-like cells (CSCs) and is involved in tumor progression and chemotherapy resistance. Previously, we reported that this pathway is activated in a subset of osteosarcoma CSCs and that doxorubicin induced stemness properties in differentiated cells through Wnt/β-catenin activation. Here, we investigated whether pharmacological Wnt/β-catenin inhibition, using a tankyrase inhibitor (IWR-1), might constitute a strategy to target CSCs and improve chemotherapy efficacy in osteosarcoma...
