Tg (−1.0ins:EGFP) zebrafish were overfed for 10 days with or without PM feeding, as described previously [22 (link)]. The fish were then fasted overnight and anesthetized by placing them in a tank containing 500 ppm of 2-phenoxyethanol (Wako Pure Chemicals, Osaka, Japan). Enhanced green fluorescent protein (EGFP) signaling was captured using a BZ-X710 fluorescence microscope (Keyence, Tokyo, Japan). The EGFP intensity was quantified using ImageJ software (National Institutes of Health, Bethesda, MD, USA), as described in our previous study [22 (link)].
