Paternal Benzo[a]pyrene Exposure Modulates MicroRNA Expression Patterns in the Developing Mouse Embryo

Figure 2

Unsupervised hierarchical clustering analysis of the relative expression of 102 miRNAs after filtering and normalization of the data. The hierarchical clustering analysis is based on similarities in gene expression. Red samples represent upregulated miRNAs whereas green samples represent downregulated miRNAs. The blue color code represents six upregulated miRNAs, and the purple color code represents six downregulated miRNAs, which were selected for further analysis.
