Extracellular vesicles derived from microRNA-150-5p-overexpressing mesenchymal stem cells protect rat hearts against ischemia/reperfusion
Figure 3.TXNIP is the target of miR-150-5p. (A) The binding sites between miR-150-5p and TXNIP as predicted by http://www.microrna.org/. (B) The relative luciferase activity determined by dual-luciferase reporter gene assay. (C) The miR-150-5p expression in myocardium determined by RT-qPCR, normalized to U6; * p < 0.05 vs. the sham group (sham-operated rats); n =12. (D) The mRNA expression of TXNIP in myocardium determined by RT-qPCR, normalized to GAPDH. (E) The protein expression of TXNIP in myocardium normalized to GAPDH determined by Western blot analysis. (F) The expression of miR-150-5p in cardiomyocytes in response to miR-150-5p-agomir and miR-150-5p-antagomir determined by RT-qPCR. * p < 0.05 vs. the agomir-NC group (I/R rats treated with agomir-NC); # p < 0.05 vs. the antagomir-NC group (I/R rats treated with antagomir-NC). Measurement data were presented as mean ± standard deviation. Comparison between two groups was analyzed by unpaired t-test. The cell experiment was repeated 3 times independently.
