Enforced-expression of circRNA_000203 could increase expressions of Col1a2, Col3a1 and ?±-SMA in mouse cardiac fibroblasts. over-expression of circRNA_000203 could eliminate the anti-fibrosis effect of miR-26b-5p in cardiac fibroblasts.
CircRNA_000203 enhances the expression of fibrosis-associated genes by derepressing targets of miR-26b-5p, Col1a2 and CTGF, in cardiac fibroblasts.
