CAMK4 and Cerebral ischemia: To further examine the possible miRNA-sponging mechanism of circ-camk4 in the MCAO model of cerebral ischemia injury, we performed bioinformatic analyses to generate a circ-camk4-miRNA-target gene interaction network, which will provide a reference for study of the association of differentially expressed circRNAs, miRNAs and their potential targets.
