Metabolomic signatures associated with LDLR functional status
(A) VIP plots of each metabolite variation in pairwise comparisons of defective/defective, null/defective, and null/null groups; the dashed lines indicate the threshold for the significant differences.
(B) Hierarchical clustering heatmap of LDLR status-associated metabolite intensities in different groups.
(C) PCA scores plot of the differentiated metabolites; each point represents an individual sample. CE = cholesterol esters, TAG = triacylglycerides, LysoPC = lysophosphocholines, LysoPC O = alkyl LysoPC, LysoPE O = alkyl lysophosphoethanolamines, LysoPA = lysophosphatidic acid, LPI = lysophosphatidylinositol.
