sp1 transcription factor

Mithramycin A (Plicamycin) 是一种dna 结合的抗肿瘤抗生素，选择性特异性蛋白1 (Sp1)抑制剂，通过降低Sp1蛋白抑制多种肿瘤的生长。特异性蛋白1 (Sp1)是一种锌指转录因子，调节多种细胞功能，促进肿瘤进展。

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.
