Figure 6

PCA biplot based on covariation of Slc DEGs using the expression profiles, which comprised RNA-Seq FPKM data for three brain regions. Red points: active variables; Blue points: active observations. W1, W2, W3: winners; C1, C2, C3: controls. Figure demonstrates distinct intergroup clustering of Slc DEGs. VTA: ventral tegmental area, NAcc: nucleus accumbens; PFC: prefrontal cortex.
