Cancer, a leading global health concern, is characterized by uncontrolled cell proliferation, resulting in a myriad of complications. The identification of specific molecular markers associated with various cancer types has paved the way for targeted therapies and personalized medicine. Among these markers, the epithelial-mesenchymal transition (EMT) has garnered significant attention due to its pivotal role in cancer metastatic spread and treatment resistance.
EMT is a complex process involving a cascade of molecular events wherein epithelial cells undergo a transformation. Since EMT involves a comprehensive reprogramming of epithelial cells, leading to a loss of their characteristic cellular adhesion and polarity, while simultaneously acquiring mesenchymal traits, it is intricately linked to invagination, migration, plasticity, and malignancy. EMT is instrumental in the malignant progression of neoplasms, contributing significantly to the increased metastatic potential and therapy resistance in cancer cells. Interaction among cancer cells in the tumor microenvironment has been shown to induce EMT by auto- and ⁄ or paracrine secretion of mediators such as growth factors, cytokines, and ECM proteins.The understanding EMT will enable elucidation of the complex molecular and cellular dynamics underlying tumor progression and will also pave the way for new and more effective therapeutic approaches. Recently, addressing EMT represents a significant challenge in the development of advanced cancer therapeutics.
Colorectal cancer (CRC) is the second-leading cause of cancer-related death in the World. EMT has become a hot issue in CRC because strong inducers of EMT (such as TGF-β) can initiate EMT and regulate metastasis, microenvironment, and immune system resistance in CRC. Despite advances in cytotoxic and targeted therapy, resistance to chemotherapy remains as one of the greatest challenges in long-term management of incurable metastatic CRC. Although EMT has been found to play a critical role in CRC drug resistance and metastasis, the nature of the intrinsic links remains unclear. Current strategies for targeting EMT is to inhibit the EMT to prevent metastasis and invasionand to reverse the EMT to restore the epithelial characteristics of cancer cells, making them more sensitive to treatment.
Present study delves into the multifaceted factors that influence EMT regulation in cancer progression, metastasis and drug resistance, and summarizes the studies conducted by our cancer research group on targeting of EMT in cancer, especially colorectal cancer.
