Figure 1. Metabolite profiles between the hypothalamus (HP) and pituitary gland (PG) of pigs exhibiting varying levels of aggression. (IMAGE)
Caption
(a)−(c) are Principal Component Analysis (PCA) of metabolites identified from different tissues (HP vs PG) and aggression (the hypothalamus of the most aggressive (HPM) vs the hypothalamus of the least aggressive (HPL), the hypothalamus of the least aggressive pigs (HPL) vs the hypothalamus of the most aggressive pigs (HPM)). (d) Pie chart depicting the categories of metabolites. (e) and (f) represent cluster analysis of all detected metabolites using Mfuzz and Kmeans clustering methods, respectively. (g) The number of differentially expressed metabolites (DEMs) (VIP > 1 and p < 0.05) identified in different tissues (PGL vs HPL, PGM vs HPM) and aggression (PGL vs PGM, HPL vs PGM).
