General description
An aureolic acid type tricyclic pentaglycoside antibiotics with anti-tumor properties. Binds to G-C rich DNA and displaces Sp1 transcription factor from its sites in the promoters of selected oncogenes, such as c-Myc and c-Src. Mithramycin A-induced inhibition of Sp1 activity has been linked to greater DNA damage and cell death in cells that are homozygous for SNP309. Specifically reduces the levels of MDM2 in human ductal breast epithelial tumor cell line, T47D (5-fold reduction at 200 nM), but does not affect cells that are wild-type for SNP309. Shown to induce myeloid differentiation of leukemic blasts that leads to reduction in the level of expression of c-Myc and c-Abl proto oncogenes that harbor G-C rich promoters. Inhibits Mcl-1 activity and mTOR phosphorylation (Ser2448) in prostate cancer cells without affecting normal human prostate epithelial cells. Shown to reduce expression of endogenous transient receptor potential vanilpod receptor (TRPV1)-like protein in dorsal root ganglionic neurons.
