Altered expression of the miR-25 has been implicated in many human malignant progression as oncogene or tumor suppressor. However, the precise role of miR-25 in osteosarcoma progression remains largely unclear. This study aimed to investigate the role and underlying mechanism of miR-25 in osteosarcoma. In this study, we demonstrated that miR-25 was significantly downregulated in osteosarcoma cell lines and tissues and that lower miR-25 was associated with advanced tumor-node-metastasis stage and lymph node metastasis...

PD-1 and its ligands have been shown to play a significant role in evasion of malignant tumour cells from the immune system. Last year, the Unites States Food and Drug Administration (FDA) approved anti-PD-1 inhibitors for treatment of non-small cell lung carcinoma and recently expanded the use of immunotherapy for metastatic urothelial cell carcinoma and Hodgkin lymphoma. However, studies on expression of PD-1 and its ligand in malignant bone and soft tissue sarcoma are sparse. In this study, we evaluated PD-1 and PD-L1 expression on variants of liposarcomas and rhabdomyosarcomas, osteosarcomas and chondrosarcomas...

BACKGROUND The transcription factor 21 (TCF21) gene is believed to be a tumor suppressor gene. TCF21 gene polymorphisms were found to play a role in the tumorigenesis of some solid malignancies. We raised a hypothesis that genetic polymorphisms of TCF21 were correlated with risk and prognosis of osteosarcoma. MATERIAL AND METHODS We recruited 225 young osteosarcoma individuals and 250 cancer-free controls. Five tagging SNPs (TCF21 rs2327429 T>C, rs2327433 A>G, rs2327433 A>G, rs12190287 C>G, and rs4896011 T>A) were genotyped...

Osteosarcoma is a kind of primary malignant bone tumor with the highest incidence and an extraordinarily poor prognosis and early pulmonary metastasis formation as a frequent occurrence. Transcriptional positive coactivator 4 (PC4) has multiple functions in DNA replication, transcription, repair and chromatin organization, even in tumorigenesis. However, the precise function of PC4 in osteosarcoma is still unclear and controversial. In this paper we found PC4 was upregulated in patient-derived osteosarcoma tissues compared to normal...

Schwannoma is a benign tumor derived from Schwann cells that cover myelinated nerve fibers (1). Among primary bone tumors, intraosseous schwannoma accounts for less than 0.2% (2). We are reporting a rare case of an 18-year-old female presented with swelling in the posterior right thigh. The patient was asymptomatic and this was incidentally discovered by her massage therapist. However, the swelling was gradually growing since then. The plain radiograph findings were suggestive of a benign bone tumor. MRI with gadolinium was performed for further evaluation but it demonstrated suspicious features as evidenced by the extra osseous enhancing soft tissue component...

BACKGROUND: Current therapies for bone cancers - either primary or metastatic - are difficult to implement and unfortunately not completely effective. An alternative therapy could be found in cold plasmas generated at atmospheric pressure which have already demonstrated selective anti-tumor action in a number of carcinomas and in more relatively rare brain tumors. However, its effects on bone cancer are still unknown. METHODS: Herein, we employed an atmospheric pressure plasma jet (APPJ) to validate its selectivity towards osteosarcoma cell line vs...

MicroRNAs (miRNAs) are small, non-coding RNAs that are key regulators of gene expression by directly binding to the 3'-untranslated region of their target mRNAs, resulting in translational repression or degradation of mRNA. It has been demonstrated that miRNAs have key roles in a variety of human malignancies, including osteosarcoma. The present study aimed to assess the molecular mechanism of miR-93 in the regulation of osteosarcoma cell proliferation. Reverse-transcription quantitative PCR and western blot assays were used to examine mRNA and protein expression...
