Histological analysis of the musculus gastrocnemius of 24–30 weeks old SOD1-G93A/low mice. The musculus gastrocnemius of 24, 27, and 30 weeks old male SOD1-G93A/low mice was evaluated for region size (A), numerical density of acetylcholine receptors at the postsynaptic surface of neuromuscular junctions by fluorophore-conjugated α-bungarotoxin labeling (B), and numerical density of phosphorylated neurofilaments (C) compared to ntg littermates. Two-way ANOVA with Tukey's and Sidak's multiple comparison post hoc test; n = 4 per group. Mean + SEM. */#p < 0.05. (D) Representative images of α-bungarotoxin (white), phosphorylated neurofilaments (pNeurofilaments, red), and protein gene product (PGP) 9.5 (green) triple labeling in the musculus gastrocnemius of a 30 weeks old male SOD1-G93A/low mouse compared to ntg littermate.
