Transcriptomic similarities among 12 samples from six Japanese participants in the cold exposure experiments. a Principal component analysis of RNA-seq data plotted according to the first (horizontal axis) and second (vertical axis) principal components. b Heatmap of Euclidean distance between expression vectors. Euclidean distance was calculated using the R dist function. The color intensity reflects the transcriptomic similarity between samples. c Hierarchical clustering of expression for 50 genes with the highest variance across samples. Colors represent normalized gene expression levels
