Heat map of miRNA expression profile in exposed workers and controls. Unsupervised hierarchical clustering analysis of the relative expression level of 22 miRNAs (measured by qPCR), and the clustering analysis is based on similarities in miRNA expression pattern. Red pixels represent up-regulated miRNAs whereas green pixels represent down-regulated miRNAs. Samples are horizontally labelled based on the exposure group they belong to (blue: exposed group and purple: control group). Vertically, blue labelled miRNAs (n = 5) indicate significantly differentially expressed miRNAs. Data are presented as log2-transformed normalized relative expression values.
