The cardiac protective human circular RNA circKLHL20_009 sponges miR-31-5p to ameliorate myocardial hypertrophy and fibrosis through suppressing β-catenin signaling.
The expression of the circRNA circKLHL20_009 was significantly upregulated in the myocardium of patients with heart failure and in human cardiomyocytes treated with angiotensin II and an artificial circRNA sponge, circSPmiR31, effectively mitigated cardiac hypertrophy and fibrosis by suppressing miR-31-5p binding to Dk...
