The expression of circRbms1 in MI mice and hypoxia-induced H9c2 cells. A Heat map showing the differentially expressed circRNA in the heart tissues of two sham mice and two MI mice from the GEO database (GSE133503). B Infarct size in the sham mice and MI mice. C Expression of circRbms1 in the heart tissues of sham mice (n = 6) and MI mice (n = 6), assessed by qRT-PCR. D Expression of circRbms1 in hypoxia-treated and untreated H9c2 cells, assessed by qRT-PCR. E, F RNase R assay (E) and ActD assay (F) to confirm the circular characteristic of circRbms1. All experiments were repeated three times. ***P < 0.001
