Abstract

Fibronectin extra domain B (FN‑EDB) is a unique domain of FN), whose expression is significantly upregulated in the tumor microenvironment (TME). FN‑EDB plays a key role in tumor cell adhesion, angiogenesis and invasion, and is closely related to tumor malignancy and poor prognosis. Moreover, the high expression of FN‑EDB in multiple cancer types makes it a potential therapeutic target. However, comprehensive studies of the mechanism of FN‑EDB in different cancer types and its potential as therapeutic targets are lacking. The present study aimed to explore the general role of FN‑EDB in multiple types of cancer and to integrate the knowledge of cell biology, molecular biology and immunology, so as to give a comprehensive understanding of the role of FN‑EDB in TME. Furthermore, by focusing on the use of FN‑EDB in clinical diagnosis and treatment, the potential of targeting FN‑EDB as a diagnostic and therapeutic target was evaluated and the progress in clinical trials of these drugs was discussed. By searching web sites such as PubMed and web of science, various high‑quality studies including RNA sequencing, drug experiments, cell experiments, animal models, clinical randomized controlled experiments and large‑scale cohort studies were collected, with sufficient evidence to support a comprehensive evaluation of the function and potential application of FN‑EDB. The present study revealed the general role of FN‑EDB in multiple types of cancer and evaluated its potential as a diagnostic and therapeutic target. It also provided a basis for future development of more effective and precise cancer therapies.
