Establishment and characterization of GFP–G3BP1 knock-in zebrafish. (A) Schematic representation of the gene editing strategy used to insert GFP into the zebrafish g3bp1 locus. (B) Top, z-stacked picture showing the expression pattern of GFP–G3BP1 in 1 dpf embryo under basal conditions. Bottom, GFP reporter signal overlapped with bright-field image. Scale bars: 200 µm. (C) Stress granules in lens, retina and midbrain cells of 1 dpf GFP–G3BP1 knock-in zebrafish when exposed to 42°C for 0 or 10 min, and at 3 and 6 min after the removal of heat stress shock. Enlarged images of the areas in the midbrain region marked by yellow squares are shown in the lower panels. Scale bars: 10 µm.
