ABSTRACT:
By analyzing the mechanism for inducing a histone deacetylase inhibitor (Trichostatin A)-mediated expression of cyclin-CDK inhibitory factor having a proliferation suppressing effect (tumor-suppressing effect), it was revealed that the binding of Sp3 to the Sp1 binding sequence within a promoter is important in the expression of the above factor. Thus, a novel antitumor agent can be developed by screening a pharmaceutical agent capable of elevating Sp3 activity.
