Forkhead box protein M1 is a protein that in humans is encoded by the FOXM1 gene.[1][2][2] The protein encoded by this gene is a member of the FOX family of transcription factors.[1][3]



FOXM1 is known to play a key role in cell cycle progression where endogenous FOXM1 expression peaks at S and G2/M phases.[4] FOXM1-null mouse embryos were neonatal lethal as a result of the development of polyploid cardiomyocytes and hepatocytes, highlighting the role of FOXM1 in mitotic division. More recently a study using transgenic/knockout mouse embryonic fibroblasts and human osteosarcoma cells (U2OS) has shown that FOXM1, regulates expression of a large array of G2/M-specific genes, such as Plk1, cyclin B2, Nek2 and CENPF, and plays an important role in maintenance of chromosomal segregation and genomic stability.[5]

FOXM1 gene is now known as a human proto-oncogene.[6] Abnormal upregulation of FOXM1 is involved in the oncogenesis of basal cell carcinoma, the most common human cancer worldwide.[7] FOXM1 upregulation was subsequently found in the majority of solid human cancers including liver,[8] breast,[9] lung,[10] prostate,[11] cervix of uterus,[12] colon,[13] pancreas,[14] and brain.[15]

There are three FOXM1 isoforms, A, B and C. Isoform FOXM1A has been shown to be a gene transcriptional repressor whereas the remaining isoforms (B and C) are both transcriptional activators. Hence, it is not surprising that FOXM1B and C isoforms have been found to be upregulated in human cancers.[4]

The exact mechanism of FOXM1 in cancer formation remains unknown. It is thought that upregulation of FOXM1 promotes oncogenesis through abnormal impact on its multiple roles in cell cycle and chromosomal/genomic maintenance.

FOXM1 overexpression is involved in early events of carcinogenesis in head and neck squamous cell carcinoma.[16]
