Metabolic signature of phosphoethanolamine and arginine pathways predicts prognosis and immunotherapy resistance in lung adenocarcinoma
Background Metabolic reprogramming is a hallmark of lung adenocarcinoma (LUAD). However, the prognostic significance of phosphoethanolamine (pEtn) and arginine metabolism-related genes remains poorly defined. This study aimed to develop and externally validate a pEtn- and arginine metabolism-related gene signature for...
