Metabolic pathways regulating lipid metabolism in PBTs, and specific molecular signatures related to plasma membrane receptors, nuclear receptors, and the metabolism of specific lipid subtypes. Arrows indicate good (↑) or bad (↓) prognosis associated with the high expression of ACSL4, GALC, FABP5, FADS1, and SMS2. CER: ceramide FFA: free fatty acids, LDs: lipid droplets, LPA: lysophosphatidic acid, PI3K: phosphatidyl inositol kinases, PLs: phospholipids, PLC: phospholipase C, SM sphingomyelin, S1P: sphingosine phosphate, UPR: unfolded protein response.
