Noncoding RNAs regulate the initiation and progression of osteosarcoma (OS). The role of long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) playing in OS and whether the function it working out was achieved through HDAC4 pathway remain uncovered. In this study, we illustrated that MALAT1 was upregulated and was correlated with poor prognosis in OS patients. Meanwhile, we demonstrated that a depression of MALAT1 suppressed proliferation and promoted apoptosis in OS cell line HOS and 143B...

Osteosarcoma is the most common primary malignancy of bone in children and young adults, the highest incidence peak is during adolescence and doesn't have any gender predominance. The main site of metastasis are the lungs and extrapulmonary cases are occasional. The incidence of metastasis in the Central Nervous System (CNS) is 2-6.5%, increase to 10-15% in patients with pulmonary metastases. Therefore, metastatic disease of the CNS is rare and the information on such patients is limited. Here, we describe a case of a 20-year old patient diagnosed with osteosarcoma in the left distal femur stage IIB, he developed pulmonary disease, during palliative chemotherapy experienced relapse to the brain classified as recursive partitioning analysis (RPA) class II, and was treated with external radiotherapy (30 Gy in 10 fractions) and later he had a poor evolution and died...

Long noncoding RNAs (LncRNAs) have been reported to participate in cancer development, including osteosarcoma. Here, in our study, we observed that lncRNA metastasis-associated lung adenocarcinoma transcription 1 (MALAT1) was remarkably overexpressed in osteosarcoma. However, the role it plays in osteosarcoma proliferation mediated by miR-206/cyclin-dependent kinase 9 (CDK9) axis remains uninvestigated. It was found that miR-206 was decreased and CDK9 was elevated in human osteosarcoma cells including MG63, Saos-2, U2OS, and KHOS compared with human osteoblast cell line hFOB 1...

It is well established that fibrotic remodeling of the tumor microenvironment favors tumorigenesis, but whether fibrosis underlies malignant progression in other ways is unclear. Here, we report that adaptive myofibroblastic reprogramming of osteosarcoma stem cells (OSCs) results in a critical advantage when establishing lung macro-metastases and spheroid growth but does not affect the growth of primary lesions or monolayer cultures. FGFR2 signaling in OSCs initiates fibrosis, whereas the resultant fibronectin (FN) auto-deposition sustains fibrogenic reprogramming and OSC growth, resembling the process employed by non-malignant myofibroblasts to cause tissue fibrosis...

Circulating cancer exosomes are microvesicles which originate from malignant cells and other organs influenced by the disease and can be found in blood. The exosomal proteomic cargo can often be traced to the cells from which they originated, reflecting the physiological status of these cells. The similarities between cancer exosomes and the tumor cells they originate from exhibit the potential of these vesicles as an invaluable target for liquid biopsies. Exosomes were isolated from the serum of eight osteosarcoma-bearing dogs, five healthy dogs, and five dogs with traumatic fractures...

BACKGROUND/AIMS: Gain-of-function of mutant p53 is associated with a high rate of lung metastasis in osteosarcoma. To investigate the mechanism of mutant p53-induced osteosarcoma metastasis, expression array analysis was performed, comparing non-metastatic osteosarcomas from p53+/- mice with metastatic osteosarcomas from p53R172H/+ mice. Onzin (Plac8) was identified as one of the genes upregulated in p53R172H/+ mouse metastatic osteosarcomas. Accordingly, we investigated the role of ONZIN in human osteosarcoma metastasis...

Osteosarcoma (OS) is one of most malignant bone tumors in early adolescence, which is a highly metastatic cancer and pulmonary metastasis is the most common cause of death. Thus, the development of efficient approaches to discover potential compounds that target metastasis of OS remains a topic of considerable interest. In this study, subtractive Cell-SELEX was performed to screen OS metastasis specific DNA aptamers by using cell lines with similar tumorigenic potentials but opposite metastatic aggressiveness (highly metastatic 143B cells and non-metastatic U-2 OS cells as the target and negative cells, respectively)...

Background: Osteosarcoma (OS) is a common malignant tumor that predominantly occurs in adolescents. Its most common metastasis is to the lungs. As shown in our earlier study, lysosome-associated membrane glycoprotein 3 (LAMP3) is highly upregulated in metastatic OS. However, its role in the regulation of OS cell viability and apoptosis remains unknown. Methods: We knocked down and overexpressed LAMP3 in OS cells and assessed the cell viability and apoptosis. Then, we investigated the expression of apoptosis-associated genes to identify the downstream gene(s) of LAMP3 ...

BACKGROUND: Complete metastasectomy is the best predictor of survival in patients with osteosarcoma pulmonary metastases. There has been some controversy in the literature regarding the prognostic significance of the timing of occurrence of lung metastasis. METHODS: We reviewed the clinical course of all osteosarcoma patients with pulmonary metastases treated by metastasectomy in our hospital from January 2008 through December 2016. Each patient who underwent metastasectomy was placed into one of three groups based on whether lung metastases were present at initial presentation (Group 1), developed during chemotherapy (Group 2), or appeared after completion of chemotherapy (Group 3)...

Over the last three decades, the prognosis of osteosarcoma has remained unchanged; the prognosis for patients with lung metastasis is still poor, and the development of new treatments is urgently required. We previously showed that aggressive osteosarcoma cells express more tissue factor (TF) and demonstrate enhanced extrinsic pathway capacity. Furthermore, tumor growth can be suppressed with the anticoagulant low molecular weight heparin. However, the molecular mechanisms underlying TF regulation are still unclear...

Lung metastasis is a major cause of mortality in patients with osteosarcoma (OS). A better understanding of the molecular mechanism of OS lung metastasis may facilitate development of new therapeutic strategies to prevent the metastasis. We have established high- and low-metastatic sublines (LM8-H and LM8-L, respectively) from Dunn OS cell line LM8 by using in vivo image-guided screening. Among the genes whose expression was significantly increased in LM8-H compared to LM8-L, the transcription factor lymphoid enhancer-binding factor 1 (LEF1) was identified as a factor that promotes LM8-H cell extravasation into the lungs...

Epidermal growth factor-like domain-containing protein 7 (EGFL7), a member of the epidermal growth factor (EGF)-like protein family, is a potent angiogenic factor expressed in many different cell types. EGFL7 plays a vital role in controlling vascular angiogenesis during embryogenesis, organogenesis, and maintaining skeletal homeostasis. It regulates cellular functions by mediating the main signaling pathways (Notch, integrin) and EGF receptor cascades. Accumulating evidence suggests that Egfl7 plays a crucial role in cancer biology by modulating tumor angiogenesis, metastasis, and invasion...

Osteosarcoma is the most common bone malignancy that occurs in the young population. After osteosarcoma cells metastasize to the lung, prognosis is very poor owing to difficulties in early diagnosis and effective treatment. Recently, connective tissue growth factor (CTGF) was reported to be a critical contributor to osteosarcoma metastasis. However, the detailed mechanism associated with CTGF-directed migration in bone neoplasms is still mostly unknown. Through the in vivo and in vitro examination of osteosarcoma cells, this study suggests that VCAM-1 up-regulation and increased osteosarcoma cell migration are involved in this process...
