MicroRNA-744 promotes proliferation of osteosarcoma cells by targeting PTEN

MicroRNAs (miRNAs/miRs) are non-coding RNAs that regulate protein synthesis by targeting mRNAs for translational repression or degradation. Previous studies have reported that aberrant expression of miR‑744 may be involved in human osteosarcoma; however, the underlying mechanisms remain elusive. In the present study, the expression levels of miR‑744 and its downstream signals were determined by reverse transcription‑quantitative PCR and western...
