a ECR is a target of let-7. Dual luciferase reporter assay results are represented as mean ± SEM of triplicate samples. b The recombinant plasmid pcDNA3.1 containing the ECR gene, including a 960-bp ORF and a 298-bp 3-UTR, was transfected into BHK cells. The expression of ECR was measured by qPCR. Data are presented as the mean ± SEM of triplicate samples. *P < 0.05, **P < 0.01, ***P < 0.001 (Student’s t-test)
