Targeting FOXM1 in colon and liver cancer
C olorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer-related death
in the United States.Therefore, development of novel therapeutic strategies for the treatment of CRC is extremely important.
FOXM1 overexpressed in the majority of CRC and overexpression of FOXM1 plays a critical role in colorectal cancer. Since the
FOXM1 regulatory network is a major predictor of adverse outcomes in human cancers, inactivation of FOXM1 by the FOXM1
inhibitors an attractive treatment strategy. Nucleophosmin (NPM) belongs to the nucleophosmin/nucleoplasmin family of
chaperones, which are ubiquitously expressed in mammalian cells. FOXM1 interacts with NPM in human cancer cells including
CRC cells and NPM knockdown in human cancer cells led to significant down-regulation of FOXM1. Our data suggest that
in human cancer cells NPM interacts with FOXM1 and their interaction is required for sustaining the level and localization of
FOXM1. We identified two compounds that inhibit NPM/FOXM1 interaction and suppress FOXM1 expression in CRC cell
lines. In addition, these compounds synergize with 5-FU in HCT116 CRC cells. NPM consists of pentamers that dimerize into a
decamer. The compounds are predicted to bind at two sites on NPM homo-oligomerization domain and they would likely block
NPM oligomerization. Therefore, by disrupting monomer-monomer interactions, they are also precluding binding of NPM and
FOXM1. We hypothesize that since FOXM1 contributes to the progression and metastasis of CRC, targeting FOXM1 with small
molecules will improve treatment outcomes for CRC patients.
