Fig. 3From: Genome-wide expression profiling in muscle and subcutaneous fat of lambs in response to the intake of concentrate supplemented with vitamin EMultivariate analysis based on gene expression profile data in subcutaneous fat. a Principal component analysis (PCA) score plots distinguishing between the subcutaneous fat of lambs fed concentrate (triangle), and supplemented with vitamin E in the treatment (+). b Partial least squares-discriminant analysis (PLC-DA) based on gene expression profile data. c Important features identified by PLS-DA. The top 15 genes are ranked by VIP scores. The colored boxes on the right indicate the relative expression of the corresponding gene in each group under study. d A bar graph showing the top 25 genes correlating with treatment (CON, VE). Variables with the same distance from 0 with similar positions are positively correlated. Those with the opposite direction are negatively correlated The light pink bars indicate genes with a positive correlation with the given pattern of change of treatmentBack to article page
