[Retracted] miR-509-5p Inhibits the Proliferation and Invasion of Osteosarcoma by Targeting TRIB2

Figure 5

The miR-509-5p hypothesis. miR-509-5p binding to the 3′-UTR region of TRIB2 sequentially inhibits the bioactivity of the tumor suppressor gene p21, suggesting that miR-509-9p is an OS suppressor.
