Fig. 1From: Differential regulation of miRNA and mRNA expression in the myocardium of Nrf2 knockout miceNrf2 Deletion and Sample Clustering: a Real-time quantitative PCR with cardiac RNA confirms Nrf2 ablation in knockout hearts (n = 4–6/group). b Hierarchal clustering analysis for all samples used in next-generation RNA sequencing (RNAseq) (n = 3–4/group). Clustering was performed for all genes with FPKM ≥1 in at least two samples and revealed distinct grouping of wild-type and knockout genotypes. ***p < 0.001Back to article page
