Cardiac miRNA expression changes induced by prediabetes


ABSTRACT: The aim of the experiment was the analysis of key molecular changes with an unbiased, transcriptomics-based approach in a prediabetes model. Small RNA sequencing analysis was applied to explore the expression changes resulted high-fat chow (supplemented with 40% lard) diet for 21 weeks and a single low dose of streptozotocin (20 mg/kg) treatment at week 4. Long-Evans rats were used in the present study. Left ventricular samples(n=6) of both prediabetic and control groups were analyzed.

Little is known about the mechanism of prediabetes-induced cardiac dysfunction. Therefore, we aimed to explore key molecular changes with transcriptomic and bioinformatics approaches in a prediabetes model showing heart failure with preserved ejection fraction phenotype. To induce prediabetes, Long-Evans rats were fed a high-fat diet for 21 weeks and treated with a single low-dose streptozotocin at week 4.
