Hsp83 facilitates JH-induced Met nuclear import. Immunohistochemistry with the anti-V5 antibody reveals the subcellular localization of Met-V5 in fat body cells isolated from the indicated genotypes and different treatments. GA, in vitro treatment with 1 μg/ml of geldanamycin for 2 h; JHA, in vitro treatment with 1 μm methoprene for 2 h; GA+JHA, GA for 2 h and JHA for 2 h; DMSO, the control treatment. A, Met-V5 was detected at 3 h AIW when the JH titer is high. B, heat shock was performed at 6 h AEL for 15 min, and Met-V5 was detected in clones of Met-V5-overexpressed fat body cells, which were marked with GFP, at 3 h AIW. C, Met-V5 was detected at 96 h AEL when the JH titer is low. D, heat shock was performed at 6 h AEL for 15 min, and Met-V5 was detected in cell clones at 96 h AEL.
