MicroRNA ‐320a inhibits invasion and metastasis in osteosarcoma by targeting cytoplasmic polyadenylation element‐binding protein 1

In conclusion, our study demonstrates that miR‐320a plays a critical role in osteosarcoma progression and may provide a potential therapeutic target for osteosarcoma.

AbstractMelatonin is an indole produced by the pineal gland at night under normal light or dark conditions, and its levels, which are higher in children than in adults, begin to decrease prior to the onset of puberty and continue to decline thereafter. Apart from circadian regulatory actions, melatonin has significant apoptotic, angiogenic, oncostatic, and antiproliferative effects on various cancer cells. Particularly, the ability of melatonin to inhibit skeletomuscular sarcoma, which most commonly affects children, teenagers, and young adults, is substantial. In the past few decades, the vast majority of references have ...

AbstractEwing sarcoma (ES) and Ewing-like sarcomas are highly aggressive round cell mesenchymal neoplasms, most often occurring in children and young adults. The identification of novel molecular alterations has greatly contributed to a profound reappraisal of classification, to the extent that the category of undifferentiated round cell sarcoma has significantly shrunk. In fact, in addition to Ewing sarcoma, we currently recognize three main categories: round cell sarcomas withEWSR1 gene fusion with non-ETS family members,CIC-rearranged sarcomas, andBCOR-rearranged sarcomas. Interestingly, despite significant morphologic ...

Authors: Gang W, Tanjun W, Yong H, Jiajun Q, Yi Z, Hao H Abstract Osteosarcoma (OS) is the most common primary bone tumor that affects adolescents and young adults. Disruption of microRNA (miRNA) regulation is well established in the pathophysiology of different cancers, including OS. Increased expression of miR-9 in OS positively correlates with the tumor size, clinical stage, and distant metastasis. In the present study, we used two different OS cell lines, MG-63 and Saos-2, as in vitro models. Small interfering RNA against miR-9 and miR-9 mimics were used to study the function of miR-9 in these two cell lines. W...

Osteosarcoma (OS) is the most common primary bone malignancy and is a leading cause of cancer-related death in children and young adults. Combination chemotherapy developed 3 decades ago significantly improved long-term survival compared to surgery alone. However, despite notable tumor cytoreduction and remission, the 5-year survival rate has remained static at ∼70% since, and the surviving patients have high chemoresistance with sustained risk of recurrent OS that has propensity to metastasize. After metastasis, the 5-year survival rate is abysmally low (∼10% to 20%). Emerging new evidence has revealed that within...

Abstract Osteosarcoma (OS), the most common malignant bone tumor, is the main cause of cancer-related death in children and young adults. Despite the combination of surgery and multi-agent chemotherapy, patients with OS who develop resistance to chemotherapy or experience recurrence have a dismal prognosis. MicroRNAs (miRNAs) are a class of small noncoding RNAs that repress their targets by binding to the 3'-UTR and/or coding sequences, leading to the inhibition of gene expression. miR-221 is found to be upregulated in tumors when compared to their matched normal osteoblast tissues.   We also observed signifi...

This study is designed to evaluate the efficacy of Fur A against OS. The effect of Fur A on cell viability was assessed by Cell Counting Kit-8 (CCK-8) assay. Western blotting and quantitative real-time PCR (qRT-PCR) were performed to determine the protein and mRNA level of sphingosine kinase 1 (SphK1), respectively. To validate the role of SphK1 in the pro-apoptotic activity of Fur A, overexpressing SphK1 vector and siRNA targeting SphK1 were utilized to transfect OS cells. Moreover, a OS xenograft murine model was used to analyze the therapeutic efficacy of Fur A in vivo. Fur A treatment led to a dose-dependent decrease i...

Authors: Fan H, Lu S, Wang S, Zhang S Abstract Osteosarcoma is the most common type of malignant bone cancer, which often affects teenagers and young adults. The present study aimed to screen for critical genes and microRNAs (miRNAs/miRs) involved in osteosarcoma. A total of four microarray datasets (accession numbers GSE32981, GSE21257, GSE14827 and GSE14359) were downloaded from the Gene Expression Omnibus database. Following data preprocessing, module analysis was performed to identify the stable modules using the weighted gene co‑expression network analysis (WGCNA) package. The differentially expressed g...
