LC Sciences microarray for mirnas and mrnas
A, Representative images after TTC staining indicate that although the area at risk (AAR, red and white) is comparable between the different treatment groups, the infarcted area (IA, white) is smaller in the tiny 15b-treated animals (control indicates control oligonucleotide). B, Quantification of cross sections of the infarcted hearts indicate that the AAR is ≈50% of the LV for all 3 treatment groups, whereas administration of 0.5 mg/kg of tiny 15b during reperfusion results in a significant reduction in infarct size compared with either saline or control oligo (*P<0.05 versus saline and control by ANOVA; control indicates control oligonucleotide). C, Real-time PCR analysis on tissue of the ischemic region 24 hours after reperfusion indicates inhibition of miR-15b in response to tiny 15b treatment (*P<0.05 versus saline and control oligonucleotide treated by ANOVA). D, Left ventricular end-diastolic pressure recordings 24 hours after reperfusion reveals an increase with saline treatment and a reduction with tiny 15b treatment (control indicates control oligonucleotide, *P<0.05 versus sham Kruskal-Wallis test). E, Ontology analysis of transcripts upregulated ≥1.5-fold in the ischemic region of hearts 24 hours after reperfusion treated with tiny 15b treatment compared with saline, based on <t>microarray</t> profiling. Negative regulators of apoptosis and cell death are significantly overrepresented. F, Echocardiography shows a reduction in ejection fraction (EF) and increases in LV volumes 2 weeks after infarct, all of which are significantly improved in response to tiny 15b treatment (*P<0.05 versus saline and control by ANOVA for EF and LVESV, versus saline only LVEDV; sham indicates no ischemia/reperfusion; control, control oligo). G, Representative images of Picrosirius red-stained cross sections demonstrate a reduction in collagen content of the left ventricle 2 weeks after reperfusion with tiny 15b treatment. Quantification of fibrosis as a percentage of total left ventricular area reveals a statistically significant reduction in the tiny 15b-treated group (*P<0.05 versus saline-treated by ANOVA). LV indicates left ventricle.
