These results indicate that STAT3 and STAT5 are direct targets of NSC-370284, which can interfere with the binding of STAT3/5 to TET1 promoter region and thereby suppress the transcription of TET1. Similarly, a previous study also reported a compound C48, a structural analog of NSC-370284, can bind directly to the DNA-binding domain of STAT3 protein and lead to apoptosis and inhibition of tumor cell growth37. The gene discussed is TET1; the disease is neoplasm.
