title: Overexpressed transcription factor FOXM1 contributes to the progression of colorectal cancer.
abstract: Forkhead box M1 (FOXM1) is a characteristic proliferation‑associated transcription factor, which is overexpressed in various types of human cancer. The aim of the present study was to determine the expression of FOXM1 in a large collection of colorectal cancer (CRC) samples. Between March 2012 and January 2014, 96 patients with histologically diagnosed CRC were recruited into the current study. Using immunohistochemistry, reverse transcription‑quantitative polymerase chain reaction and western blotting, mRNA and protein expression levels of FOXM1 in CRC tissue samples were determined. The function of FOXM1 in the CRC cells was evaluated by small interfering RNA‑mediated depletion of FOXM1, followed by analyses of cell proliferation and invasion. High levels of staining for FOXM1 were observed in significantly more CRC tissue samples: 85.42% (82/96) of CRC tissue samples compared with 18.75% (18/96) of adjacent normal mucosa tissue samples. Silencing FOXM1 inhibited the proliferation of LoVo cells, which express a relatively high level of FOXM1, and the invasion and migration of LoVo cells were also markedly suppressed. The data from the present study suggested that the pathogenesis of human CRC may be mediated by FOXM1, and that FOXM1 inhibition may provide a promising therapeutic strategy for CRC.
