Inactivation of Gadd34 restores motor function and ameliorates the neurophysiological and morphological deficits in S63del mice. (A) Rotarod analysis of motor function in WT, Gadd34Δc/Δc, S63del and S63del/Gadd34Δc/Δc. Error bars, SEM; *, P < 0.05; **, P < 0.01 for S63del/Gadd34Δc/Δc relative to S63del; n = 20–25 animals. (B and C) Electrophysiological analysis showing NCV and F-wave latency; n = 10–12 animals; *, P < 0.05; **, P < 0.01, relative to S63del by Student’s t test. NCV, nerve conduction velocity. (D) Semithin sections stained with toluidine blue from P28 and P180 WT, S63del, and S63del/Gadd34Δc/Δc sciatic nerves. Arrows, amyelinated axons in P28 S63del nerve. Arrowhead, demyelinated fiber/onion bulb in 6-mo-old S63del nerve. Bar, 10 µm. (E) Number of amyelinated axons at P28, and of demyelinated fibers (F) and onion bulbs (G) at 6 mo. Error bars, SEM; *, P < 0.05; **, P < 0.01; ***, P < 0.001, by Student’s t test; n = 20–35 microscopic fields from 4–6 animals per genotype.
