Furthermore, the results showed that vascular endothelial growth factor (VEGF) expression was down-regulated in osteosarcoma cells after miR-145 transfection.
Future studies should examine the relationship between VEGF isoform expression and patients' survival and the relationship between VEGF isoform expression and EMMPRIN expression, which could be helpful for predicting the prognosis of patients with osteosarcoma.
In addition, we detected the expression of vascular endothelial growth factor (VEGF) and signal transducer and activator of transcription 3 (STAT3) in osteosarcoma cell treated with Eag1 small interfering RNAs (siRNAs).
Transfection of human osteosarcoma 9901 and HOS cells with pSilenceApe1 resulted in a dose-dependent loss of Ape1 protein. pSilenceApe1 also significantly suppressed the expression of vascular endothelial growth factor (VEGF) protein in the 9901 cells.
The aim of this study was to determine the prognostic significance of blood VEGF and blood and urinary basic fibroblast growth factor (bFGF) levels in osteosarcoma patients, both at diagnosis and during treatment.
It has been reported that VEGFR expression correlates with the outcome of patients with osteosarcoma and circulating VEGF level has been associated with the development of lung metastasis.
Effect of cortisol on cell proliferation and the expression of lipoprotein lipase and vascular endothelial growth factor in a human osteosarcoma cell line.
Moreover, we show that WISP-1 promotes VEGF-A expression in human osteosarcoma cells, subsequently inducing human endothelial progenitor cell (EPC) migration and tube formation.
Cyr61 and VEGF expressions moderately correlated with each other in osteosarcoma, and exhibited significant association with Enneking stage and distant metastasis.
The study demonstrates potent growth and pulmonary metastasis inhibitory effects of VEGF-siRNA on osteosarcoma in vivo and in vitro, which could potentially be applicable to the treatment of cancers as an antiangiogenic therapeutic in the near future.
In summary, it was demonstrated that miRNA-638 expression change in patients with osteosarcoma and an <i>in vitro</i> model via PLD1 and VEGF expression and miRNA-638 may be potential clinical indicators of osteosarcoma.
We found that serum concentrations of CXCL8 and vascular endothelial growth factor were elevated in osteosarcoma patients in comparison with those in NCs.
In this study, we investigated the effects of PEDF on growth and vascular endothelial growth factor (VEGF) expression in MG63 human cultured osteosarcoma cells.
This study shows that CCL3 promotes VEGF-A expression and angiogenesis in human osteosarcoma cells by down-regulating miR-374b expression via JNK, ERK, and p38 signaling pathways.
Knockdown of EWS/Fli-1 using siRNA on a Ewing's sarcoma cell line (A673) suppressed VEGF-A expression, and transfection of EWS/Fli-1 into a human osteosarcoma cell line increased VEGF-A expression.
These effects were associated with decreased expression of Notch-1 and its downstream genes, such as vascular endothelial growth factor and matrix metalloproteinases, as well as increased expression of a panel of tumor-suppressive microRNAs (miRNAs), including miR-34a, miR-143, miR-145 and miR-200b/c that are typically lost in osteosarcoma.
