Suppression of the FOXM1 transcriptional program via novel small molecule inhibition

ABSTRACT: The transcription factor FOXM1 binds to sequence-specific motifs on DNA (C/TAAACA) through its DNA binding domain (DBD), and activates proliferation- and differentiation-associated genes. Aberrant overexpression of FOXM1 is a key feature in oncogenesis and progression of many human cancers. Herein we identify novel inhibitors of FOXM1 that block DNA binding from a high-throughput screen applied to a library of 54,211 small molecules. One compound, FDI-6 (NCGC00099374) is studied in depth and is shown to bind directly to FOXM1 protein, displace the transcription factor from genomic targets in MCF-7 breast cancer cells, and induce concomitant transcriptional down-regulation. Global transcript profiling of MCF-7 cells by RNA-seq shows that FDI-6 specifically down regulates FOXM1-activated gen
