Fig. 4From: Downregulation of microRNA-21 inhibited radiation-resistance of esophageal squamous cell carcinomaCell viability of miR-21 mimics and inhibitor transfected-TE-1 cells after exposure of 6 Gy for 48 h. After transfection with miR-21 mimics and inhibitor, cells were irradiated with 6 Gy for 48 h. And then, the cell viability was detected by CCK8 assayBack to article page
