摘要

Hepatocellular carcinoma (HCC) is a common type of primary liver cancer and is considered the third leading cause of cancer-related deaths worldwide. The high aggressiveness and resistance to therapies exhibited by HCC present significant challenges to global public health. As the primary metabolic organ in the human body, the liver undergoes substantial metabolic reprogramming during carcinogenesis, affecting various metabolic pathways including those involved in carbohydrates, lipids, and amino acids. Notably, disruptions in amino acid metabolism play a critical role in the initiation and progression of HCC, helping to sustain its malignant characteristics. This review aims to provide an in-depth analysis of the alterations observed in aromatic amino acids metabolism, branched chain amino acids (BCAAs) metabolism, glutamine metabolism, and other amino acid metabolism processes, including serine, arginine, and methionine, along with the expression patterns of associated metabolic enzymes. Furthermore, it discusses potential therapeutic approaches and their clinical relevance, offering insights and strategies for improving HCC diagnosis and treatment in the future.
