PubMed 32326003 · doi:10.3390/ijms21082872
What was done
This narrative review synthesizes literature on the deregulation of the glutaminolysis pathway in cancer, focusing on how intermediate metabolic steps are altered to sustain tumor growth and how non-coding RNAs participate in regulating glutamine metabolism.
What was found
The abstract provides no numerical data. It summarizes qualitative biological mechanisms: cancer cells upregulate glutaminolysis for energy, Krebs cycle anaplerosis, macromolecule synthesis (amino acids, purines, pyrimidines, fatty acids), and reactive oxygen species defense. Non-coding RNAs are highlighted as key regulators of these glutaminolytic processes.
Why it matters
The review outlines how non-coding RNA-mediated regulation of glutamine metabolism contributes to cancer maintenance, pointing to potential therapeutic targets and prognostic biomarkers.
Limits
The paper is a non-systematic narrative review providing no quantitative synthesis, empirical sample size, or risk-of-bias assessment. Findings reflect laboratory and pre-clinical mechanism-based models without clinical trial evidence.
