Targeted Metabolomic Profiling of Free Amino Acids in Human Colon Tumor-116 and Normal Colon Cells
Introduction: Metabolic reprogramming is a defining feature of colorectal cancer, and amino acid metabolism constitutes a major functional axis supporting proliferation, stress tolerance, and treatment resistance. We aimed to compare the intra-cellular free amino acid profile of human colon tumor-116 (HCT-116) colon ca...
