DCX and Wilson disease: We also calculated the proliferation rate of DCX+ cells (Figure 3K) and found that the WD group showed a significant reduction in the percentage of DCX+BrdU+/DCX+ cells (Mdn = 0.76%, IQR: 0.55–0.83) when compared to the control group (Mdn = 1.54%, IQR: 1.41–1.6; U = 0; P = 0.004).
