LPC 14:0 (C589, lysophosphatidylcholine 14:0) is associated with tumor progression and recurrence and can be used as a biomarker for certain cancers [26]; elevated levels of LPC may promote the release of inflammatory cytokines, such as TNF-α and IL-6, which show a positive correlation with the malignant proliferation of cancer cells. The gene discussed is TNF; the disease is cancer.
