Whole-animal AChR levels in Daf1–/– and Daf1+/+ mice 48 hours after McAb-3 mAb injection. The bars (NI, noninjected; I, injected) show changes in levels normalized to noninjection levels. Daf1–/–, n = 8; Daf1+/+, n = 4. *P > 0.05. The noninjection levels in the Daf1–/– mice were not decreased relative to wild-type controls (0.213 vs. 0.160 pmol/g muscle).
