MYC and cancer: In the field of lipidomics, arachidonic acid is a signaling precursor that has attracted interest for anti-cancer therapy.184, 185 A recent study of lipidomic profiling showed that lung tumors possess higher levels of arachidonic acid-containing phospholipids and phosphatidylinositols compared to normal tissue.185 Myc inactivation caused a significant decrease in arachidonic acid and its lipid metabolites.185 These results suggest that arachinonic acid and its metabolites can serve as biomarkers in precision diagnosis.
