MiR-21, PTEN, and VEGF expressions in CMECs after transfection. (A) Quantitative levels of miR-21in CMECs among different groups (control, NC, miR-21 mimics, miR-21 inhibitors, miR-21 mimics + lenti PTEN, and miR-21 mimics + VEGF siRNA). (B) Western blot analysis of PTEN and VEGF in CMECs with GAPDH as internal control. (C, D) Quantitative protein level of PTEN (C) and VEGF (D) CMECs. Data are presented as mean ±SD for 3 independent experiments. *
