Effects of CORT receptor antagonists on CORT-induced increases in Phox2b immunoreactivities. SH-SY5Y cells were simultaneously exposed to 100 nM CORT, CORT plus either mifepristone, spironolactone or both, as well as mifepristone, spironolactone alone for 3 days (N=5/group). Upper panel: Phox2b proteins detected by western blotting. Lower panel: Quantitative analyses of band densities. * p<0.05, compared to the control (Con), † p<0.05, compared to the CORT ingestion group. M: treated with mifepristone alone; S: treated with spironolactone; for other abbreviations see legend of Fig. 6.
