Glutamine Metabolism-associated Molecular Heterogeneity and Prognosis in Pancreatic Adenocarcinoma.
BACKGROUND Pancreatic Adenocarcinoma (PAAD) is characterized by pronounced molecular heterogeneity and profound metabolic reprogramming. Glutamine metabolism plays a critical role in sustaining tumor growth and shaping the tumor microenvironment; however, its contribution to molecular heterogeneity, immune characterist...
