Level 5 - mechanism / opinion, no new human data
Narrative review and theoretical mechanism-based framework with no new human data.

What was done
The authors synthesized mechanistic evidence to propose a framework explaining why proliferating and cancer cells engage in aerobic glycolysis (the Warburg effect) despite its inefficient generation of ATP compared to oxidative phosphorylation.
What was found
No quantitative data or sample metrics are reported in the abstract. The authors propose that cancer metabolism is adapted to facilitate nutrient incorporation into biomass (nucleotides, amino acids, and lipids) needed for cell duplication, supported by findings that proliferation signaling pathways and cancer-associated mutations reprogram metabolic pathways toward biomass accumulation rather than ATP yield.
Why it matters
It provides a conceptual rationale for the Warburg effect as an adaptive biosynthetic strategy rather than a simple mitochondrial defect, pointing toward metabolic pathways as therapeutic targets in oncology.
Limits
This is a narrative review and theoretical perspective containing no original empirical data, quantitative meta-analyses, or clinical human outcome measurements.
