Figure Lengend Snippet: CircRNA mitogen‐activated protein kinase kinase kinase 5 (circMAP3K5) acts as a sponge for miR‐22‐3p in cardiomyocytes. A, Predicted potential interactions between circMAP3K5 and miR‐22‐3p according to Miranda software. B, quantitative real‐time polymerase chain reaction (qRT‐PCR) results showing expression level of miR‐22‐3p in H9c2 cells. C, Luciferase activity in wild‐type circMAP3K5 (circMAP3K5 WT) and a mutant with a miR‐22‐3p binding site (circMAP3K5 MUT) in 293 T cells transfected with a control mimic or a miR‐22‐3p mimic. D, qRT‐PCR results depicting levels of miR‐22‐3p expression in H9c2 cells transfected with either si‐MAP3K5 NC or si‐MAP3K5. E, qRT‐PCR results showing levels of miR‐22‐3p expression in H9c2 cells transfected with either pLc‐MAP3K5 vector or pLc‐MAP3K5. F, Western blots showing expression levels of the apoptosis regulatory protein. Statistically significant difference: * p < .05 ( n = 3). HG, high glucose; miRNA, microRNA.
Article Snippet: These circRNAs were amplified and transcribed into fluorescent cRNA using a random primer method (Arraystar Super RNA Labeling Kit; Arraystar). labeled cRNAs that were hybridized to Arraystar Rat circRNA Array V2.0 (8 × 15 K) with a total of 14 145 circRNA probes on the chip.
