Lipid stores are depleted specifically in the body wall muscle of C. elegans after swim exercise. Quantification of the number of lipid droplets and representative confocal images at different time points post-exercise in tissue-specific Perilipin 1-GFP strains: intestine, P _daf-22 PLIN1::GFP (a, b); hypodermis, P _Y37A1B.5 PLIN1::GFP (c, d); and body wall muscle, P _unc-54 PLIN1::GFP (e, f). Each point represents a single animal (n = 47–61 animals); statistical significance determined by unpaired two-tailed Student’s t test. Scale bars: 20 μm. ****P < 0.0001. ns non-significant
