Treatment of myxoid liposarcoma cells in vitro and in vivo with peroxisome proliferator-activated receptors gamma agonists induced terminal differentiation[33], although phase II studies with the peroxisome proliferator-activated receptors gamma agonist Rosiglitasone did not show the antitumor effect in advanced myxoid liposarcoma patients[34]. The gene discussed is PPARG; the disease is myxoid liposarcoma.
