Invasion; MiR-874; Osteosarcoma; Prognosis; Proliferation

Dysregulation of microRNAs (miRs) is associated with cancer development and progression and aberrant expression of miR-874 have been found in some types of cancer. However, the expression and function of miR-874 in osteosarcoma remain unclear. The aim of this study was to explore the effects of miR-874 in osteosarcoma tumorigenesis and development. The expression level of miR-874 was ... more

Dysregulation of microRNA (miR) is often associated with cancer development and progression. Aberrant expression of miR-134 has been found in some types of cancer. However, its expression and function in osteosarcoma remain unclear. The aim of this study was to explore the effects of miR-134 in osteosarcoma tumorigenesis and development. The expression level of miR-134 was quantified by ... more

Invasion; miR-184; Osteosarcoma; Proliferation

Osteosarcoma is a highly malignant cancer that often appears in teenagers. It is the most frequently occurring primary bone tumor, and can easily metastasize, resulting in high mortality. MicroRNAs express abnormally in osteosarcoma, and may function as oncogenes or tumor suppressors. Recent studies showed that microRNA184 (miR-184) is abnormally expressed in multiple tumors, and is ... more

Bone neoplasms; Osteochondroma; Osteosarcoma

Osteochondroma is a cartilage capped benign tumor developing mainly at the juxta-epiphyseal region of long bones. The rate of malignant transformation, mainly into chondrosarcoma, is estimated to be less than 1-3%. Transformation into osteosarcoma is very rare and has been reported only thirteen times. There is little information on treatment and outcome. We report the case of a secondary ... more

DNA repair genes; Osteosarcoma; Overall survival; Polymorphism

We conducted a perspective study to investigate the role of ERCC1 (rs11615), ERCC2 (rs13181 and rs1799793), ERCC4 (rs1800067), and ERCC5 (rs17655) in NER pathway in the prognosis of osteosarcoma patients. In total, 146 osteosarcoma patients were recruited between 2008 and 2013. ERCC1 rs11615, ERCC2 rs13181 and rs1799793, ERCC4 rs1800067, and ERCC5 rs17655 gene polymorphisms were assessed ... more

Chemotherapy; ERCC1; ERCC2; Osteosarcoma; Overall survival; Single nucleotide polymorphism

We assessed the role of single nucleotide polymorphisms (SNPs) in ERCC1 and ERCC2 genes in the clinical outcomes for osteosarcoma patients receiving cisplatin-based treatment. A perspective study was conducted on 260 patients with osteosarcoma during 2010 and 2011. A polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assay was used to assess ... more

Osteosarcoma; Polymorphisms; VEGF

The aim of this study was to assess the role of the VEGF -2578C/A, +936C/T, and -460T/C gene polymorphisms in the development of osteosarcoma. A total of 182 patients with osteosarcoma and 182 age- and gender-matched healthy controls were enrolled into our study during January 2011 and December 2013. Genotype frequencies of the VEGF -2578C/A and -460T/C alleles in controls ... more

Clinical outcome; ERCC1; ERCC2; Osteosarcoma; Polymorphism

We aimed to evaluate the influence of four SNPs in ERCC1 and ERCC2 on the response to cisplatin-based treatment and on clinical outcome in patients with osteosarcoma. We identified 186 patients with osteosarcoma diagnosed between April 2009 and April 2011 who were eligible for inclusion in our study. Genotyping of ERCC1 rs11615, rs3212986, and rs2298881; and ... more

Centrality analysis; Differential expression network; Osteosarcoma; Pathway-enrichment analysis

Despite recent advances in osteosarcoma diagnosis and therapy, much remains unclear about the molecular mechanisms involved in the disorder, and the discovery of novel drug-targeted genes is essential. We explored the potential molecular mechanisms and target genes involved in the development and progression of osteosarcoma. First, we identified the differentially expressed genes in ... more

6-biphosphatase 3; 6-Phosphofructo-2-kinase/fructose-2; miR-26b; Oncogene; Osteosarcoma

MicroRNAs regulate target gene expression and are involved in cell proliferation, apoptosis, differentiation, tumor invasion, and cancer stem cell regulation, among other processes. MicroRNA-26b (miR-26b) is closely related to tumor occurrence and development. In this study, we analyzed miR-26b expression in osteosarcoma tissue, its effect on Saos-2 osteosarcoma cell proliferation and invasion ... more
