Esophageal squamous cell carcinoma (ESCC) is the most common subtype of esophageal cancer worldwide. The most commonly mutated gene in ESCC is TP53. Using a combinatorial genetic and carcinogenic approach, we generate a novel mouse model of ESCC expressing either mutant or null p53 and show that mutant p53 exhibits enhanced tumorigenic properties and displays a distinct genomic profile. Through RNA-seq analysis, we identify several endocytic recycling genes, including Rab Coupling Protein (Rab11-FIP1), which are significantly downregulated in mutant p53 tumor cells. In 3-dimensional (3D) organoid models, genetic knockdown of Rab11-FIP1 results in increased organoid size. Loss of Rab11-FIP1 increases tumor cell invasion in part through mutant p53 but also in an independent manner. Furthermore, loss of Rab11-FIP1 in human ESCC cell lines decreases E-cadherin expression and increases mesenchymal lineage-specific markers, suggesting induction of epithelial-mesenchymal transition (EMT). Rab11-FIP1 regulates EMT through direct inhibition of Zeb1, a key EMT transcriptional factor. Our novel findings reveal that Rab11-FIP1 regulates organoid formation, tumor cell invasion, and EMT.
