The miRNA expression profiles in the heart of rats. (a) Heat maps show significantly up- and down-regulated mRNAs in the heart of rats fed HFD and control rats for 24 weeks (n = 7 in each experiment). miRNA expression profiles were clustered hierarchically. (b) Volcano Plot for differential miRNA expression in the heart of rats. The green dost represent the most significantly upregulated miRNAs (more than five-fold, P < 0.05), including miR-3583-3p, -410-5p, -146b-3p, -764-5p, -330-5p, and -324-3p, in the heart of rats fed HFD for 24 weeks. The arrow indicates miR-322-5p. (c) qPCR analysis of the six most-up-regulated miRNAs in the heart of rats. All results are standardized to the levels of 18S rRNA and the means ± SD of three experiments (n = 6 in each experiment). *P < 0.05; **P < 0.01 relative to control (normal group).
