    Objective To investigate the role of FOXM1, beta-catenin and TCF4 in esophageal cancer (EC) and their relationship to VM (Vasculogenic Mimicry). Methods CCK-8 were performed to examine EC cell proliferation in FOXM1 silenced cells. EC cell migration and invasion were investigated through wound healing and Transwell assays, respectively. The formation of pipe like structures were assessed in 3D cultures. The expression of Foxm1, beta-catenin, Tcf4 and E-cadherin were investigated through western blot, RT-qPCR and immunohistochemistry (IHC) staining. The relationship between FOXM1 expression, clinic-pathological features, and overall survival (OS) were further analyzed. Results A loss of FOXM1 expression correlated with the OS of ESCC patients. FOXM1 silencing led to a loss of cell growth and suppressed cell migration and invasion in ESCC cells. VM structures were identified in ESCC tissues and human EC cell lines. Mechanistically, FOXM1 was found to promote tumorigenesis through the regulation of beta-catenin, Tcf4, and E-cadherin in EC cells, leading to the formation of VM structures. Conclusions These findings highlight FoxM1 as a novel therapeutic target in ESCC. Keywords: Esophageal cancer, FOXM1, beta-Catenin, Tcf4, VM, Proliferation, Invasion, Migration
