The nephroblastoma overexpressed (NOV) gene, a member of the CCN gene family that encodes secreted proteins involved in a variety of processes including tumorigenesis, is often altered in a variety of tumors, including osteosarcoma. Recent studies indicated that NOV promotes osteosarcoma metastasis, but its biological functions and molecular mechanisms on osteosarcoma proliferation have yet to ...

BACKGROUND MicroRNAs (miRNAs) are a class of endogenously expressed, small noncoding RNAs, which suppress its target mRNAs at the post-transcriptional level. Studies have demonstrated that miR-34a, which is a direct target of the p53 tumor suppressor gene, functions as a tumor suppressor and is associated with the tumor growth and metastasis of various human malignances. However, the role of mi...

Osteosarcoma, the most prevalent primary malignancy of bone, is often presented with high-grade subclinical metastatic disease that metastasizes at very early stages. Exosomes, as molecular information carriers, may play a potent role in occurrence and development tumors through oncogenic reprogramming tumor-associated macrophages (TAMs). In this study, we will investigate effect osteosarcoma-d...

Osteosarcoma is a malignant mesenchymal neoplasm that accounts for the majority of primary bone tumors in dogs and shares biological and clinical similarities with osteosarcoma in humans. Despite dose intensification with conventional cytotoxic therapies, survival times for dogs and humans diagnosed with high-grade osteosarcoma have not changed in the past 20 years, with the principal cause of ...

OBJECTIVE The purpose of the present study was to determine whether type III IFN can modulate the autophagic response in human osteosarcoma cell. METHODS Human osteosarcoma cell were treated with Interferon-λ1. We investigated that Interferon-λ1 could inhibit the invasive ability of osteosarcoma cells by Matrigel invasion assay. Autophagy were assessed by acridine orange staining, MDC stainin...

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 analy...

Osteosarcoma is a rare type of cancer associated with a poor clinical outcome. Even though the pathologic characteristics of OS are well established, much remains to be understood, particularly at the molecular signaling level. The molecular mechanisms of osteosarcoma progression and metastases have not yet been fully elucidated and several evolutionary signaling pathways have been found to be ...

Osteosarcoma, the most common primary bone tumor in children and young adolescents, is characterized by local invasion and distant metastasis. But the detailed mechanisms of osteosarcoma metastasis are not well known. In the present study, we found that βig-h3 promotes metastatic potential of human osteosarcoma cells in vitro and in vivo. Furthermore, βig-h3 co-localized with integrin α2β1 in o...

PURPOSE Osteosarcoma is the most common cancer of bone occurring mostly in teenagers. Despite rapid advances in our knowledge of the genetics and cell biology of osteosarcoma, significant improvements in patient survival have not been observed. The identification of effective therapeutics has been largely empirically based. The identification of new therapies and therapeutic targets are urgentl...

Osteosarcoma is the most common malignant bone tumor. Most patients diagnosed with osteosarcoma are less than 20 years of age. Osteosarcoma cells proliferate rapidly and invade other tissues. At present, neoadjuvant chemotherapy is the primary pharmacodynamic strategy to prevent the progression of osteosarcoma. However, adverse effects of this strategy limit its long‑term application. Previous ...
