OBJECTIVES: Long non-coding RNAs (lncRNAs), a group of transcripts with length greater than 200 nucleotides, have been involved in multiple pathophysiological processes of the human body, especially in tumorigenesis and progression of cancers. The aberrant expression of lncRNAs processes crucial functions involved in proliferation, apoptosis and metastatic capacity of cancers. Recent studies have revealed that small nucleolar RNA host gene 1 (SNHG1), a long non-coding RNA transcribed from UHG, was located in chromosome 11...

Osteosarcoma is the most common paediatric primary non-hematopoietic bone tumor; the survival is related to the response to chemotherapy and development of metastases. KMT2C is a chromatin-modifying and remodelling protein and its expression has never been studied in osteosarcoma. The aim of this study was to understand the role of KMT2C in the osteosarcoma carcinogenesis and metastatic progression to identify a new molecular target and to provide new therapeutic approach. We performed the immunohistochemical and gene expression analysis of KMT2C in 32 samples of patients with diagnosis of osteosarcoma with known clinic-pathological data and we analysed the expression of genes involved in the metastatic pathway in four osteosarcoma cell lines by blocking the KMT2C expression using siRNA...

BACKGROUND: Osteosarcoma (OS) is the most frequent pediatric malignant bone tumor. OS patients have not seen any major therapeutic progress in the last 30 years, in particular in the case of metastatic disease, which requires new therapeutic strategies. The pro-apoptotic cytokine Tumor necrosis factor (TNF)-Related Apoptosis Inducing Ligand (TRAIL) can selectively kill tumor cells while sparing normal cells, making it a promising therapeutic tool in several types of cancer. However, many OS cell lines appear resistant to recombinant human (rh)TRAIL-induced apoptosis...

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...

The lungs are a common site of metastatic spread of an osteosarcoma. An affiliated simultaneous bilateral spontaneous pneumothorax (SBSP) is a rare clinical sequela of this malignancy. In this case report, we present the clinical circumstances of a young teenager who presented to our clinical setting following a diagnosis of osteosarcoma. We also illustrate the postulated pathophysiology, the tools for diagnosis and a subsequent management for this rare clinical entity.

Metastasis of osteosarcoma to the muscles is extremely rare. F-sodium fluoride (NaF) is a bone-seeking agent that can also localize extraosseous calcifying lesions. We report the case of a 33-year-old woman with osteosarcoma of the right fibula treated with surgery and chemotherapy 2 years back who was referred for F-NaF PET-CT to evaluate possible metastatic lesions. F-NaF PET-CT unexpectedly detected 2 foci of soft tissue increased tracer uptake in the right lateral abdominal and left paraspinal muscles, which corresponded to the focal calcification in the muscles...

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...

Introduction: The overall survival rate of patients with osteosarcoma (OS) and pulmonary metastases has remained stagnant at 15-30% for several decades. Disulfiram (DSF) is an FDA-approved aldehyde dehydrogenase inhibitor that reduces the metastatic phenotype of OS cells in vitro . Here we evaluate its in vivo efficacy, as compared to doxorubicin chemotherapy, in a previously-validated orthotopic model of metastatic OS. Results: All treatment groups displayed a significantly reduced quantitative OS metastatic burden compared with controls...

BACKGROUND: Merkel cell carcinoma (MCC) is a rare neuroendocrine cutaneous malignancy that shares cytologic, histopathologic, and immunohistochemical features with other small round blue cell (SRBC) tumors. Although the trabecular pattern is anecdotally associated with MCC, objective data are lacking. METHODS: This was a retrospective institutional review board-approved observational study conducted on microscopic images of 79 MCCs and 74 other SRBC tumors (desmoplastic small round cell tumor, primitive neuroectodermal tumor, neuroblastoma, embryonal rhabdomyosarcoma, alveolar rhabdomyosarcoma, synovial sarcoma, carcinoid, metastatic small cell lung cancer, non-Hodgkin small cell lymphoma, retinoblastoma, medulloblastoma, nephroblastoma, small cell osteosarcoma, and round cell liposarcoma)...

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)...

The prognosis of patients with metastatic osteosarcoma is poor and has shown no significant improvement in nearly 20 years. The human epidermal growth factor (EGF) receptor (HER) family is frequently overexpressed in the majority of human carcinomas, and is involved in promoting the proliferation and survival of cancer cells. However, the role of EGFR and HER-2 expression in osteosarcoma survival remains controversial and no previous study has simultaneously investigated the association of the expression of all the four HER family members with the prognostic significance of osteosarcoma...

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 ...
