Figure 1.
Images of a fiber expressing HDAC4-GFP before and during stimulation with 10-Hz trains. A fiber expressing HDAC4-GFP is shown in Ringer's solution at RT 30 min before stimulation (−30), at the start of stimulation (0), and after stimulation for 60 or 120 minutes with 5-s duration trains of 10-Hz pulses applied every 50 s. After 2-h stimulation there is a significant decline of fluorescence in all the nuclei. Bar, 10 μm.
