Fig. 1From: Gene expression signature in mouse thyroid tissue after 131I and 211At exposureResults from hierarchical clustering analyses of genes and exposure groups after 131I and 211At exposure. Genes were hierarchically clustered according to log2-ratio values using gplots package in R/Bioconductor. The columns represent genes and rows represent exposure type. Cluster containing kallikrein genes is denoted A Back to article page
