Peroxisome proliferator-activated receptor γ ligand inhibits cell growth and invasion of human pancreatic cancer cells

Background. Peroxisome proliferator-activated receptor γ (PPARγ) is expressed in certain human cancers; ligand-induced PPARγ activation can result in growth inhibition and differentiation in these cells. However, the precise mechanism for the antiproliferative effect of PPARγ ligands is not entirely known.
