|abstract=The transcription factor [i][[TCF7L1]][/i] is an embryonic stem cell signature gene that is upregulated in multiple aggressive cancer types, but its role in skin tumorigenesis has not yet been defined. Here we document [[TCF7L1]] upregulation in skin squamous cell carcinoma (SCC) and demonstrate that [[TCF7L1]] overexpression increases tumor incidence, tumor multiplicity, and malignant progression in the chemically induced mouse model of skin SCC. Additionally, we show that downregulation of [[TCF7L1]] and its paralogue [[TCF7L2]] reduces tumor growth in a xenograft model of human skin SCC. Using separation-of-function mutants, we show that [[TCF7L1]] promotes tumor growth, enhances cell migration, and overrides oncogenic RAS-induced senescence independently of its interaction with β-catenin. Through transcriptome profiling and combined gain- and loss-of-function studies, we identified [[LCN2]] as a major downstream effector of [[TCF7L1]] that drives tumor growth. Our findings establish a tumor-promoting role for [[TCF7L1]] in skin and elucidate the mechanisms underlying its tumorigenic capacity.
