Fig. 3 . Anchorage of synaptic nuclei is abolished in Syne-1^-/- mice. (A-A''') Representative Syne-1^+/- muscle fiber with four nuclei (synaptic nuclei) clustered under the NMJ. (B-C''') No nuclei were observed under the NMJ of Syne-1^-/- mice. (D,E) Statistical analyses of synaptic nuclei based on anti-SUN2 signals. Synaptic nuclei disappeared in Syne-1^-/- mice (4.7 in Syne-1^+/+ and Syne-1^+/- vs 0.0 in Syne-1^-/-, n=140 for Syne-1⁺^/? and 210 for Syne-1^-/-, P<0.0001); the number of perisynaptic nuclei was slightly increased in Syne-1^-/- mice (0.0 in control vs 0.8 in KO, P<0.0001). Blue, DAPI; Green, anti-SUN2-labeled myonuclei; Red, BTX. Scale bar: 25 µm.
