Exercise-induced skeletal muscle damage in Tango2 deficiency. (A) Whole-mount (green) phalloidin staining of control and tango2 mutants (tango2bwg210 and tango2bwg211) in the presence or absence of methylcellulose (MC) treatment. tango2 mutants exhibited extensive overstretched sarcomeres (arrows) and damaged myofibers (arrowheads) on swimming in the MC-containing water compared to those in controls (n=6-8 in each group). Nuclei are shown in blue. Images are representative of n=6 larvae in each group. Scale bar: 5 µm. (B,C) Quantification of the swimming behavior of control and tango2 mutants (tango2bwg210 and tango2bwg211) before and after MC treatment (n=96). Two-way ANOVA (mixed model) with multiple comparisons was performed between different groups. ns, not significant; *P<0.05; **P<0.01; ***P<0.005.
