Overview of Gene Research
GOT1, also known as cytoplasmic glutamic oxaloacetic transaminase, plays a critical role in multiple metabolic pathways vital for cellular homeostasis. It is involved in classical and non-classical glutamine metabolism, glycolytic metabolism, and other pathways, and is crucial for maintaining redox balance [2].
In pancreatic cancer, GOT1 inhibition promotes ferroptosis, an oxidative, iron-dependent form of cell death. Pharmacological inhibition shows that cysteine, glutathione, and lipid antioxidant function are metabolic vulnerabilities following GOT1 withdrawal. Mechanistically, GOT1 inhibition represses mitochondrial metabolism, promotes a catabolic state, enhances labile iron availability through autophagy, and potentiates the activity of ferroptotic stimuli [1].
In CD8+ T cells, genetic deletion of GOT1 promotes the generation of memory CD8+ T cells, while GOT1 enhances proliferation by maintaining intracellular redox balance and serine-mediated purine nucleotide biosynthesis, and promotes glycolytic programming and cytotoxic function of cytotoxic T lymphocytes [3].
In conclusion, GOT1 is essential for maintaining cellular metabolic balance, especially in redox-related metabolic regulation. Studies using gene knockout models, such as in pancreatic cancer and CD8+ T cells, have revealed its role in disease-related processes like ferroptosis and T-cell differentiation. These findings contribute to understanding the mechanisms of cancer and immune-related diseases, potentially providing new targets for treatment.
