Role of epithelial-mesenchymal transition (EMT) in malignancies: current status and future prospects

Abstract

Epithelial-mesenchymal transition (EMT) is a biological process that involves the transformation of epithelial cells into more mobile and invasive mesenchymal cells. While EMT is crucial for typical physiological functions like maturation of the embryo and tissue restoration, its association with cancer often leads to tumor proliferation, metastasis, and resistance to therapy. This transition permits tumors to acquire traits that promote invasion, migration, and resistance to cell death. Therefore, unraveling the intricate mechanisms of EMT activation in cancer will contribute to the advancement of personalized medicine and the design of more effective treatments against metastatic disease. Inhibiting EMT holds the potential for restricting cancer cell invasion and metastasis, ultimately improving patient outcomes. EMT induction can be triggered by various factors, including extracellular signals, external substances, and pathological conditions such as hypoxia. This paper primarily examines the function of EMT in the initiation and progression of tumors, along with the factors that contribute to its activation. With the aid of cutting-edge technologies and improved experimental techniques, researchers can more effectively investigate the complex network of molecular events underlying EMT, leading to the identification of novel biomarkers and the advancement of therapies. By leveraging these advancements, scientists are better equipped to unravel the intricacies of EMT and pave the way for advancements in personalized medicine and improved treatment strategies for patients affected by EMT-related conditions. Understanding the cellular events and signaling cascades that drive EMT can aid in the development of interventions that disrupt or reverse this process.
