Figure 4. Heat map of altered proteins induced by STX treatment in mice. (A) Hierarchical clustering of 70 changed proteins in the hippocampus between Low dose STX exposure group and CT group. (B) Hierarchical clustering of 87 changed proteins in the hippocampus between Middle dose STX exposure group and CT group. (C) Hierarchical clustering of 86 changed proteins in the hippocampus between High dose STX exposure group and CT group. (criteria: ratio {greater than or equal to}1.2 represented up-regulation or ratio <0.83 represented down-regulation). The different color stands for a different level of protein expression, with red indicates increase and green indicates decrease when compared with CT group.
