Integrated bioinformatics analysis of miRNA expression in osteosarcoma

The expression of miRNA influencing the pathogenesis of OS have been reported previously, however, different samples selection and sequencing platforms made obvious differences in miRNA expression analysis. We aim to identify reliable prognostic and treatment biomarkers for OS by systematic analysis of miRNAs expression data sets from biased data set. Seven miRNA data sets were selected from corresponding articles. Collectively, two miRNAs, hsa-miR-19-3p and hsa-miR106b-3p, and transcription factor SIX3 were identified and may be reliable markers for prognostic and treatment of osteosarcoma.
