MicroRNAs signatures, bioinformatics analysis of miRNAs, miRNA mimics and antagonists, and miRNA therapeutics in osteosarcoma

Babak Otoukesh et al. Cancer Cell Int. .

Abstract

MicroRNAs (miRNAs) involved in key signaling pathways and aggressive phenotypes of osteosarcoma (OS) was discussed, including PI3K/AKT/MTOR, MTOR AND RAF-1 signaling, tumor suppressor P53- linked miRNAs, NOTCH- related miRNAs, miRNA -15/16 cluster, apoptosis related miRNAs, invasion-metastasis-related miRNAs, and 14Q32-associated miRNAs cluster. Herrin, we discussed insights into the targeted therapies including miRNAs (i.e., tumor-suppressive miRNAs and oncomiRNAs). Using bioinformatics tools, the interaction network of all OS-associated miRNAs and their targets was also depicted.

Keywords: MicroRNAs; Osteosarcoma; Targets; Therapy.

Possible ways to release circulating miRNAs; 3 pathways including extracellular vesicles, RNA-binding proteins and/or transfer through cell gap junction are involved. In addition, the topology of the network was analyzed based on degree metrics in order to find the most important nodes. According to the findings, 5 nodes with large degrees in our large network (i.e., > 9, see green nodes) including BCL2, VEGFA, CCND1, PTEN and MET were identified as potential hub nodes, (Additional file 1, and Fig. 2)
