Abstract

In this work, we explored the aberrant expression pattern, clinical association, and functional regulations of microRNA-1270 (miR-1270) in osteosarcoma. Among in vitro osteosarcoma cell lines and in situ tissues of osteosarcoma patients, quantitative real time-PCR was used to examine their endogenous miR-1270 expression. Clinical correlation between endogenous miR-1270 expression and clinicopathological features of osteosarcoma patients, as well as cancer patients' overall survival, was statistically examined. MiR-1270 was downregulated in 143B and MG-63 cells by lentiviral transduction. The mechanistic effects of miR-1270 downregulation on osteosarcoma in vitro proliferation and migration, as well as in vivo tumorigenesis, were further examined. MiR-1270 was aberrantly upregulated in both in vitro osteosarcoma cell lines and in situ human tumors. Statistical analysis demonstrated endogenous miR-1270 was associated with poor clinical outcomes and shorter overall survival of osteosarcoma patients. Lentivirus-induced miR-1270 downregulation inhibited cancer in vitro proliferation and migration, as well as in vivo tumorigenesis. Aberrant upregulation miR-1270 may be a prognostic biomarker for osteosarcoma patients with poor clinic...Continue Reading
