a Diagram of the luciferase pIRES2-EGFP vector. b Impact of celastrol, Cel-2, Cel-6, 17-AAG, and CHX on the translation of HCV genotype 1b IRES-dependent reporters in AD293 stable cell line. Impact of celastrol treatment on (c) HCV genotype 2a, (d) MSCV, and (e) CrPV IRES-dependent translation in AD293 cells harboring the pIRES2-EGFP plasmid was analyzed by the ratio of firefly luciferase and EGFP. f Huh-luc/neo-ET cells were transiently transfected with HA-HSP90β for 48 h and then treated with celastrol as indicated. The HA-HSP90β-associated proteins were pulled down with HA magnetic beads and analyzed by using Western blot analysis. Results are representative of three independent experiments. Data in (bf) were presented as mean ± SD (**P < 0.05 compared with each other or to DMSO treatment).
