Transcriptional activation of the mouse mammary tumor virus (MMTV)
promoter by ligand-bound glucocorticoid receptor (GR) is transient.
Previously, we demonstrated that prolonged hormone exposure results in
displacement of the transcription factor nuclear factor 1 (NF1) and the
basal transcription complex from the promoter, the dephosphorylation of
histone H1, and the establishment of a repressive chromatin structure.
We have explored the mechanistic link between histone H1
dephosphorylation and silencing of the MMTV promoter by describing the
putative kinase responsible for H1 phosphorylation. Both in vitro
kinase assays and in vivo protein expression studies suggest that in
hormone-treated cells the ability of cdk2 to phosphorylate histone H1
is decreased and the cdk2 inhibitory p21 protein level is increased. To
address the role of cdk2 and histone H1 dephosphorylation in the
silencing of the MMTV promoter, we used potent cdk2 inhibitors,
Roscovitine and CVT-313, to generate an MMTV promoter which is
associated predominantly with the dephosphorylated form of histone H1.
Both Roscovitine and CVT-313 block phosphorylation of histone H1 and,
under these conditions, the GR is unable to remodel chromatin, recruit
transcription factors to the promoter, or stimulate MMTV mRNA
accumulation. These results suggest a model where cdk2-directed histone
H1 phosphorylation is a necessary condition to permit GR-mediated
chromatin remodeling and activation of the MMTV promoter in vivo.
