(F) 3rd instar larval fat bodies were stained by BODIPY (green) for lipid droplets and DAPI (blue) for nuclei. Under high-fat conditions, RDH/CG2064 overexpression increases the lipid droplet size, and Plin2 RNAi suppresses the enlargement induced by RDH/CG2064 overexpression. Scale bar represents 25 µm.
