PTDSS1 and cancer: A second metabolism superset was centered around glycerophospholipid metabolism and contained 3 pathways (‘Glycerophospholipid metabolism’, ‘Choline metabolism in cancer’, and ‘Inositol phosphate metabolism’), 2 upregulated genes (PTDSS1 and PCYT1A), 2 downregulated genes (CDS1 and CHKA), 1 increased metabolite (MyI), and 2 decreased metabolites (Sci and FFA).
