Sox6 controls the Ca2+ response of fast-twitch fibers. (A,B) Cross section through a trunk somite of a 48 hours postfertilization (hpf) Tg(smyhc1:GCaMP3)i280 embryo, showing expression of GCaMP3 (green) is restricted to slow-twitch fibers, revealed by mAbF59 labeling (red). Nuclei are stained with DAPI (blue). (C) Stereotypical representation of the GCaMP3 signal in response to chemical stimulation indicating the three parameters measured in this analysis. (D) Response time in seconds (s) and (E) amplitude of Ca2+ response in fast and slow-twitch fibers of Tg(smyhc1:GCaMP3)i280 (Tg) and transient transgenic wild-type (+) and sox6 mutant larvae (52 to 55 hpf); Student’s two-tailed, unpaired t-test; Error bars represent standard deviation.
