Description

While the abstract notes these metabolic enzymes are affected by IDH2 reprogramming and correlate with poor prognosis, the causal relationship between their expression changes and clinical outcomes remains unexplained. This gap hinders development of prognostic biomarkers and therapeutic targets.
