Figure 1. Gene expression networks associated with determinants of midbrain SERT and TPH2 mRNA.

Figure 1

Genes (top 25) with highest correlations with Slc6a4 (a) or Tph2 (b) are graphed separately based on the direction of correlation (green: positive; red: negative). Gene node sizes represent the significance of correlation. Gene pairs with correlation coefficients (Spearman rho) above 0.5 are connected by edges (green: positive; red: negative). (c) Venn diagram showing the number of overlapping genes derived from Tph2-seeded and Slc6a4-seeded gene networks (top 100).
