A smaller number of lipid metabolism genes were overexpressed in the myxoid/round-cell liposarcomas compared to the dedifferentiated/pleomorphic liposarcomas with genes such as DGKD, EBPL, FABP5, FDFT1, LPL and PPARG upregulated in the former group, while ADM, ANXA1, ANXA4, CRYL1, GRN, PLA2G4A, PLA2G12A, PLD1 and PLTP were overexpressed in the latter [see Additional files 2 and 21]. This evidence concerns the gene GRN and liposarcoma.
