Chd4 deletion results in deregulation of Schwann cell genes induced and repressed during development. A, B, The mRNA expression levels for the indicated genes were determined by quantitative RT-PCR from sciatic nerve samples at the P8, P15, and P30 time points. Expression data are presented as a ratio of Chd4 mutant compared with wild-type mRNA levels (C). P30 protein levels of Egr2 (D), Oct6 (E), activated β-catenin (G), and P4 levels of Pmp22 (F) mirror the levels found in the mRNA expression data. Error bars indicate SD. Line represents relative level in wild-type mice. *p < 0.05; **p < 0.01; ***p < 0.005.
