Figure 5From: Comprehensive profiling of zebrafish hepatic proximal promoter CpG island methylation and its modification during chemical carcinogenesisPrincipal component analysis (PCA) scores plot of DNA methylation data. Zebrafish HCC samples (purple), healthy zebrafish liver samples (orange), positive control of artificially methylated genomic DNA (green) and negative control of artificially un-methylated genomic DNA (yellow) were separated based on treatment along the PC1 and PC2 axes.Back to article page
