PTEN was a target gene of miR-26a-5p. (A) A conserved binding site of miR-26a-5p in the 3′UTR of PTEN was identified. (B) Dual luciferase reporter assay indicated that miR-26a-5p significantly suppressed the relative luciferase activity of pmirGLO-PTEN-3′UTR as opposed to the activity seen with the control in 293 cells. (C) Western blot analysis also showed that overexpression of miR-26a-5p suppressed the expression of PTEN, while inhibition of miR-26a-5p increased the protein level of PTEN in HT1376 cells (D).
