From: Circadian variations in the liver metabolites of medaka (Oryzias latipes)
Principal component analysis (PCA) of the medaka liver metabolites during the day and at night.
(A) schematic diagram of preparation of samples and CETOFMS (B) Principal component analysis-normalized metabolic data obtained from the medaka liver at ZT4 and ZT16. Percentage values indicated on the axes represent the contribution rate of the first (PC1) and second (PC2) principal components to the total amount of variation. (C) Heat map of the hierarchical cluster analysis. The columns are the medaka liver metabolome profiles at ZT4 and ZT16. The rows show the normalized levels of each metabolite. The dendrogram for each heatmap shows the relatedness of the normalized metabolite level patterns.
