What was done
This narrative review synthesizes the biological roles of two primary facets of tumor metabolism: the Warburg effect (aerobic glycolysis and lactic acid fermentation) and mitochondrial metabolism (tricarboxylic acid cycle and electron transport chain). It also reviews existing and emerging therapeutic strategies aimed at targeting tumor glycolysis and mitochondrial processes.
What was found
The abstract reports no numerical findings, effect sizes, or experimental data. It conceptually outlines that the Warburg effect provides rapid energy acquisition and metabolic advantages for proliferation, while mitochondrial metabolism supports biosynthesis and sustained vitality, suggesting both pathways as viable therapeutic targets.
Why it matters
The paper highlights that tumor cells rely concurrently on both glycolysis and mitochondrial respiration, reinforcing the rationale for dual-pathway metabolic targeting rather than viewing these processes as mutually exclusive.
Limits
As a narrative review, the paper presents no original experimental or clinical data. The abstract contains no quantitative metrics, systematic search criteria, or specific evaluations of drug efficacy or clinical outcomes.

- context Cancer cells exhibit the Warburg effect by opting for fermentation and avoiding mitochondrial respiration even in the presence of oxygen.
