In this regard, the first comprehensive comparison of FOXM1 isoform expression employed genotype-tissue expression (GTEx) normal, The Cancer Genome Atlas (TCGA) cancer, and Target Cancer datasets [27], and validated the findings of others showing that FOXM1c has the highest expression followed by FOXM1b and FOXM1a [25,26,28]. This evidence concerns the gene FOXM1 and cancer.
