Figure 5. FGF2 and GRB2 are the target genes of miR-20b. (A–B) 24 hours after transfection, the mRNA and protein levels of FGF2 and GRB2 in the miR-20b overexpression group were significantly reduced. (C–D) The opposite effects were observed in the silencing group. (E–F) After 24 hours of exposure, FGF2, GRB2 expression levels were decreased with increasing concentrations (statistically significant in the 1 mg/L group). (*: P<0.05).
