[p53-SOAT1 Axis: A Novel Target for Tumor Lipid Metabolism and Therapy]

Cancer treatment is a significant challenge facing global medicine, with complex molecular mechanisms and drug resistance being key factors limiting treatment outcomes. Abnormal lipid metabolism is one of the important characteristics of tumors, providing metabolic support for the growth, proliferation, migration, and invasion of tumor cells. Tumor suppressor p53 protein and sterol O-acyltransferase 1 (SOAT1) play an important role in regulating cellular lipid metabolism and are closely related to the occurrence, development, and prognosis of various tumors. p53 protein regulates tumor lipid metabolism through multiple signaling pathways, while SOAT1, as a key enzyme in cholesterol esterification, is highly expressed in many tumors and accelerates tumor progression. Recent studies have shown that there may be a functional association between p53 protein and SOAT1, coordinating the regulation of lipid homeostasis in tumor cells. This article reviews the research progress on p53 protein and SOAT1 in tumor lipid metabolism, focusing on the potential mechanisms of action of the p53-SOAT1 axis in tumor development, and prospects its application prospects as a target for cancer treatment.
