AbstractThe Forkhead Box M1 (FOXM1) transcription factor plays a crucial role in regulating expression of cell cycle genes which are essentially involved in cell proliferation, differentiation and transformation. Recent studies have reported that aberrant expression of FOXM1 in a variety of human cancers is associated with their aggressive behaviour. However, the functional significance of FOXM1 in human cervical cancer is not known. We have shown that FOXM1 was significantly over-expressed in cervical squamous cell carcinoma (SCC) compared to normal cervical epithelium immunohistochemically (p < 0.001). In addition, intratumoural FOXM1 positivity was increased in cervical intraepithelial neoplasia (CIN) and carcinoma, compared with that in normal epithelium, indicating that FOXM1 is involved in tumour progression. Indeed, this is supported by clinicopathological analysis that the overexpression of FOXM1 was significantly associated with tumour late stage (p = 0.012) and cell proliferation marker, Ki67 (p < 0.001). Functionally, enforced expression of FOXM1c in FOXM1-deficient cervical cancer cells (C33A) remarkably enhanced cell proliferation and anchorage-independent growth ability. Conversely, depletion of FOXM1 by RNA interference in FOXM1-over-expressing cervical cancer cells (SiHa) caused significant inhibition on cell proliferation and anchorage-independent growth ability on soft agar. This inhibitory phenomenon was associated with the reduced expressions of cyclin B1, cyclinD1 and cdc25B but increased expression of p27 Kip1 and p21 Cip1. Our findings suggest a role for FOXM1 in the development and pathogenesis of human cervical SCC. Copyright © 2008 Pathological Society of Great Britain and Ireland.
