Exploratory experiment designed to discover new patterns targeting TP53, TP63, EFNB1, EPHB4 in human ESCC tissue samples and mouse models. Primary outcome: characterization of TP53-TP63/ΔNP63-EFNB1-EPHB4 axis role in tumorigenesis
Pathological analysis was performed to investigate the TP53-TP63/ΔNP63-EFNB1-EPHB4 axis in epithelial cancer formation and progression. The study examined how TP53 mutations lead to overexpression of ΔNP63, which in turn causes aberrant EFNB1-EPHB4 interactions. The analysis traced the progression from early precancerous lesions in the basal epithelial layer to whole epithelial layer involvement and strengthening interactions during cancer development. This work provided mechanistic insights into how TP53 mutations, a known culprit in human ESCC tumorigenesis, initiate a cascade of molecular events leading to EMT and enhanced proliferation.
