Katzenellenbogen 1,2,3*, Valeria Sanabria Guillen1 and John A. Katzenellenbogen2,4  \nAbstract  \nFOXM1 (Forkhead box M1) is an oncogenic transcription factor that is greatly upregulated in breast cancer and many other cancers where it promotes tumorigenesis, and cancer growth and progression. It is expressed in all subtypes of breast cancer and is the factor most associated with risk of poor patient survival, especially so in triple negative breast cancer (TNBC) . Thus, new approaches to inhibiting FOXM1 and its activities, and combination therapies utilizing FOXM1 inhibitors in conjunction with known cancer drugs that work together synergistically, could improve cancer treatment outcomes. Targeting FOXM1 might prove especially beneficial inTNBC where few targeted therapies currently exist, and also in suppressing recurrent advanced estrogen receptor (ER)-positive and HER2-positive breast cancers for which treatments with ER or HER2 targeted therapies that were effective initially are no longer beneficial. We present these perspectives and future directions in the context of what is known about FOXM1, its regulation, and its key roles in promoting cancer aggressiveness and metastasis, while being absent or very low in most normal non-regenerating adult tissues. We discuss new inhibitors of FOXM1 and highlight FOXM1 as an attractive target for controlling drug-resistant and difficult-to-suppress breast cancers, and how blocking FOXM1 might improve outcomes for patients with all subtypes of breast cancer.  \nKeywords FOXM1, Breast cancer, Inhibitors, Transcriptional activity, Drug resistance  \nBreast cancer is highly heterogeneous but FOXM1 is expressed in all subtypes  \nBreast cancer is the most common cancer in women worldwide, and its incidence has been increasing due to growth of the aging population [1], and emergent trends in lifestyle factors including obesity, physical inactivity,  \n*Correspondence:  \nBenita S.

The nature of the breast tumors also varies by ethnicity, with African American women having the highest rate of the most difficult to treat triple negative breast cancer (TNBC) subtype compared with other ethnic groups in the United States [3].  \nA major challenge in treating breast cancer effectively is the very heterogeneous nature of the disease, which encompasses a wide array of histological and molecular characteristics [1, 3, 4] that divides broadly into 6 intrinsic subtypes: Normal-like, Basal-like, Claudin-low, human epidermal growth factor 2 (HER2)-enriched, Luminal B, and Luminal A. While estrogen receptor (ER)-targeted and HER2-targeted therapies are subtypespecific, and are highly effective as first-line treatments [5–7], the efficacy of these therapies can change overtime, becoming less effective with treatment and disease  \n© The Author(s) 2023.
