Background

Mithramycin A is an antibiotic that binds the minor groove in GC-rich regions of DNA to inhibit transcription factor-DNA binding and prevent transcriptional activation (1). Mithramycin A is a specific inhibitor of specificity protein 1 (SP1), a ubiquitously expressed transcription factor that plays a role in control of cell growth and differentiation, apoptosis, and the immune response (2). Inhibition of SP1 by Mithramycin A leads to suppression of downstream targets, including proto-oncogenes ha-RAS12 and c-Myc13, anti-apoptotic genes survivin14 and XIAP15, and the pro-angiogenic gene VEGF. Mithramycin A inhibition of SP1 suppresses anti-apoptotic gene expression and induces caspase-dependent apoptosis (3). Several studies demonstrated that nanomolar concentrations of Mithramycin A could suppress tumor growth with no apparent effect on normal cell division. Mithramycin A was used therapeutically to treat testicular cancer and myeloid leukemia. Additional work suggests a possible role of Mithramycin A in treating cervical and colorectal cancer (4).
