Decoding the role of FOXP3 in esophageal cancer: Underlying mechanisms and therapeutic implications

Abstract

Esophageal cancer is a significant contributor to cancer-related mortality, and its poor prognosis is primarily attributed to the aggressive nature of the tumor and challenges in early detection. Currently, there are no ideal drugs developed for treatment, making it crucial to explore potential biomarkers and molecular targets for esophageal cancer. FOXP3, as a transcription factor and major regulator of regulatory T cells, not only plays a role in promoting or inhibiting tumor development in various types of cancer cells including esophageal cancer cells but also influences the function of Treg cells by regulating the expression of multiple genes. This paper provides an in-depth discussion on the functional properties, regulatory mechanisms, key signaling pathways, as well as the role and potential application of FOXP3 in treating esophageal cancer. Furthermore, it comprehensively analyzes the complex role of this transcription factor within the tumor immune microenvironment with an aim to aid in developing new potential targets for esophageal cancer treatment.
