F) Confocal images of Bmm-GFP (green) in 3rd instar larval fat bodies of different genotypes. DAPI (blue) stains nuclei. Scale bar represents 25 µm. (F) Overexpression of Plin2 decreases the level and lipid droplet localization of Bmm-GFP in fat cells from larvae with DGAT1 overexpression. (G) GFP intensity along the line across a lipid droplet from (F) was measured by ImageJ. The lipid droplet localization of Bmm-GFP, represented by two peaks, was evident in fat cells from ppl>DGAT1 larvae, but is lost in ppl>DGAT1 larvae with overexpression of Plin2. More than 30 lipid droplets of each genotype were measured. One typical image curve is shown for each genotype.
