Research Progress of Warburg Effect in Hepatocellular Carcinoma

Abstract

The Warburg effect, also called aerobic glycolysis, refers to tumor cells that metabolize glucose through glycolysis even in the presence of oxygen. This rapid breakdown of glucose fuels the fast development, growth, and migration of tumor cells. Lactate, the final product of aerobic glycolysis, contributes to an acidic environment within the tumor, promoting the formation of an immunosuppressive microenvironment and accelerating tumor progression by impeding anti-tumor immunity. Numerous studies have confirmed the critical role of aerobic glycolysis in the occurrence and development of hepatocellular carcinoma by influencing tumor cells proliferation, invasion, metastasis, apoptosis, immune escape, angiogenesis, and more. Clinical trials have shown that inhibitors of rate-limiting enzymes in the glycolysis pathway can enhance the effectiveness of sorafenib, a targeted drug for hepatocellular carcinoma, by reducing drug resistance. Additionally, active components of traditional Chinese medicine and specific compound prescriptions are gaining attention for their potential to target and regulate aerobic glycolysis in hepatocellular carcinoma. Therefore, inhibiting the aerobic glycolysis pathway holds promise as a therapeutic strategy for treating liver tumors. This manuscript aims to review the role, research directions, and clinical studies of aerobic glycolysis in hepatocellular carcinoma.
