EGFR overexpression induces activation of telomerase via PI3K/AKT‐mediated phosphorylation and transcriptional regulation through Hif1‐alpha in a cellular model of oral–esophageal carcinogenesis

Abstract excerpt

Telomerase plays an important role during immortalization and malignant transformation as crucial steps in the development of human cancer. In a cellular model of oral-esophageal carcinogenesis, recapitulating the human disease, immortalization occurred independent of the activation of telomerase but through the recombination-based alternative lengthening of telomeres (ALT). In this stepwise model, additional...
