Abstract

Osteosarcoma can be regarded as a differentiation disease that is caused by genetic and epigenetic disruptions of osteoblast terminal differentiation. Using an innovative approach of genome-wide functional screening, we have recently uncovered that forced expression of certain short RNA (19-base) may disrupt BMP9-induced bone formation from MSCs. These short RNA are designated as Disruptors of Osteogenesis induced by BMP9 (or DONs). This study determines that the candidate DONs can effectively disrupt osteogenic differentiation and bone formation from MSCs, rendering MSCs bone tumor-like phenotype in a mouse model.
