sp1 transcription factor

Mithramycin A (Plicamycin), a DNA-binding antitumor antibiotic, is a selective specificity protein 1 (Sp1) inhibitor, which inhibits the growth of various cancers by decreasing Sp1 protein. Specificity protein 1 (Sp1) is a zinc-finger transcription factor that regulates multiple cellular functions and promotes tumor progression.

NZ28, also known as NSC134754, is potent HSF1 inhibitor, which induced inhibition of HSF1, SP1 and NF-κB triggers the loss of the natural killer cell-activating ligands MICA/B on human tumor cells. Heat-shock transcription factor HSF1 has a critical role in human epidermal growth factor receptor-2-induced cellular transformation and tumorigenesis.
