Myelin-associated protein expression is unaltered in Schwann cells lacking NF-κB activation following crush injury. (A) Western blots of myelin-associated transcription factor (cJun, Krox-20) and structural (MPZ, MBP) protein expression within the distal nerve of normal (WT) and transgenic mice before (N) and 4, 12, and 31 days after injury. Lamin A/C serves as a loading control. (B) Densitometric quantification of protein expression normalized to WT naïve (N). AU: arbitrary units. Results are expressed as the mean ± SEM of 3–7 animals/group. *p<.05, unpaired Student’s t-test.
