The involvement of a vicinally spaced dithiol group in steroid binding to the glucocorticoid receptor has been deduced from experiments with the thiol-specific reagent methyl methanethiolsulfonate and the vicinal dithiol-specific reagent sodium arsenite.

Sodium arsenite-induced chemical stress leads to a substantial and specific increase in the glucocorticoid receptor-mediated transcription, resulting in maximal stimulations of more than 2000-fold by the agonist dexamethasone.

A similar shift to nuclear localization for unliganded glucocorticoid receptor is noted in L929 and WCL2 cells subjected to chemical shock (sodium arsenite).

We previously reported that activated glucocorticoid receptor-steroid complexes from rat HTC cell cytosol exist as at least two sub-populations, one of which requires a low molecular weight (700-3000 Da) factor (s) for binding to DNA.

This potentiation of hormone-induced MMTV-CAT expression was dependent on the magnitude of the stress event and on the Dex concentration, with maximal increases observed for 1 microM Dex after 2 h at 43 C or 2 h at 200 microM sodium arsenite.

Exposure of hepatocytes to either heat shock (HS;+15 degrees C) or sodium arsenite (50 microM) did not affect cell viability, but resulted in significantly higher hsp70 levels over a 24 h recovery period.
This lack of glucocorticoid responsiveness corresponded with lower glucocorticoid receptor protein levels.

Our previous studies with the thiol-specific reagent methyl methanethiolsulfonate (MMTS) and the vicinal dithiol-specific reagent sodium arsenite have established that 2 spatially close thiols (i.e. vicinal dithiols) are involved in steroid binding to the intact 98 K rat glucocorticoid receptor.
