Osteosarcoma (OS) is a highly aggressive mesenchymal malignancy and the most common primary bone tumor in the pediatric population. OS frequently presents with or develops distal metastases. Patients with metastatic disease have extremely poor survival rates, thus necessitating improved molecular insights into OS metastatic biology. Utilizing our previously characterized genetically engineered mouse model (GEMM) of metastatic OS, we identified enhanced differential expression of Transglutaminase-2 (TGM2) in metastatic OS...

Osteosarcoma is the most common malignant bone cancer that mainly affects children and young adults. Recently, the NAD+ -dependent deacetylase, sirtuin 1 (SIRT1), has been reported to play a key role in the development of malignant tumors. The study aimed to investigate the role of SIRT1 in osteosarcoma and explore its underlying oncogenic mechanisms. The prognostic value of SIRT1 in osteosarcoma was assessed through detection of SIRT1 expression based on osteosarcoma biopsy tissue. Then, to further investigate the effect of SIRT1 in osteosarcoma, osteosarcoma cells were treated with small interfering RNA SIRT1 and overexpressed SIRT1 to detect the cell migration, invasion, and epithelial-mesenchymal transition (EMT)...

Osteosarcoma (OS) is a primary malignant bone tumor in early adolescence with high metastasis and death rates. Although the combination of polychemotherapy and surgical excision increased the survival rates up to 60%, the prognosis remains poor for most patients with metastatic or recurrent osteosarcoma. However, the exact pathogenic mechanism and pivotal elements regulating tumor invasion and metastasis are largely unknown. Circular RNAs (circRNAs) are novel endogenous non-coding RNA (ncRNA) molecules that generate the cyclic structure from back splicing...

BACKGROUND: Von Willebrand factor (vWF) is a major procoagulant molecule that was shown to differentiate between metastatic and primary osteosarcoma (OS) tissues and associated with increased metastasis. However, its functional role in OS progression has yet been unclear. METHODS: The expression profile of vWF and miR-24 in human OS tissues was characterized using immunofluorescence labelling and qRT-PCR analysis. The interaction between miR-24 and vWF was identified by dual luciferase reporter assay...

Extraosseous sarcoma of the breast occurs infrequently and is a harbinger of poor prognosis. The histogenesis of this tumor is ambiguous, and it can arise both in de novo and metastatic settings. Morphologically, it is indistinguishable from its skeletal counterpart, and clinically, it presents similarly to any other subtype of breast cancer. Tumor recurrence with a propensity for hematogenous rather than lymphatic spread plagues this malicious disease. The treatment guidelines are mainly derived from the those of other extraskeletal sarcomas as the literature is limited in this context...

Osteosarcoma is the most common primary bone tumor with highly invasive characteristic and low long-term survival. Recently, epithelial-mesenchymal transition (EMT) is reported as a key event in cancer invasion and metastasis. Oridonin, a bioactive diterpenoid, has been proved to possess anti-cancer effects. However, the effect of oridonin on EMT and metastasis of osteosarcoma is unclear. In this study, we investigated the underlying mechanism of oridonin on EMT and metastasis of osteosarcoma. We found that oridonin inhibited migration and invasion of MG-63 and 143B cells...

PURPOSE: Metastatic osteosarcoma is largely treated with high-dose methotrexate (HDMTX)-based therapy, especially in the pediatric population. This mandates complex pharmacokinetic monitoring in a costly inpatient setting to mitigate unpredictable serious toxicities. Hence, a non-HDMTX-based regimen is worth exploring, especially in India and low- and middle-income countries. MATERIALS AND METHODS: All consecutive treatment-naïve patients with metastatic osteosarcoma were prospectively treated on the novel OGS-12 protocol consisting of sequential doublets of doxorubicin, cisplatin, and ifosfamide...

Osteosarcoma (OS) is a primary malignant bone tumor that mainly affects children, adolescents, and young adults. The inhibition of metastasis is a main strategy of OS therapy since the development of metastatic disease due to drug resistance remains the most important cause of death from this cancer. Considering the severe side effects of current OS chemotherapy, the identification of anti-metastatic drugs with reduced toxicity is of great interest. Chalcones are polyphenols with a basic structure consisting of an α-, β-unsaturated carbonyl system linking two aryl rings...

Hepatic carcinosarcoma (HCS) generally presents in advanced stages, demonstrates aggressive behavior, and has a poor prognosis. Other than curative primary resection, no effective treatment options exist. We present a case of resected HCS with four repeat resections for solitary lymph node recurrence followed by chemoradiotherapy with doxorubicin and ifosfamide. A 67-year-old Japanese man was admitted to our hospital for evaluation of an asymptomatic hepatic tumor. The patient underwent right hepatectomy with a presumptive preoperative diagnosis of atypical hepatocellular carcinoma...

Notch (Notch1 through 4) are transmembrane receptors that play a fundamental role in cell differentiation and function. Notch receptors are activated following interactions with their ligands in neighboring cells. There are five classic ligands termed Jagged (Jag)1 and Jag2 and Delta-like (Dll)1, Dll3, and Dll4. Recent work has established Notch as a signaling pathway that plays a critical role in the differentiation and function of cells of the osteoblast and osteoclast lineages and in skeletal development and bone remodeling...

Although the investigation into biomarkers specific for pulmonary metastasis within osteosarcoma (OS) has recently expanded, their usage within the clinic remains sparse. The current screening protocol after any OS diagnosis includes a chest CT scan; however, metastatic lung nodules frequently go undetected and remain the primary cause of death in OS. Recently, screening technologies such as liquid biopsy and next-generation sequencing have revealed a promising array of biomarkers with predictive and diagnostic value for the pulmonary metastasis associated with OS...

Human osteosarcoma 143B cells were previously stably transfected with an αv integrin green flourescent protein (GFP) vector. 143B cells expressing αv integrin-GFP were transplanted orthotopically in the tibia of transgenic nude mice ubiquitously expressing red fluorescent protein (RFP). The primary tumors acquired RFP-expressing stroma and were passaged orthotopically in the tibia in noncolored nude mice, which maintained the RFP stroma. The interaction of αv integrin-GFP expression in 143B cells with RFP-expressing host stromal cells was observed by confocal microscopy using the Olympus FV1000...
