摘要: Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is one of the best characterized nuclear hormone receptors (NHRs) in superfamily ligand-activated transcriptional factors. PPAR-gamma ligands have recently been demonstrated to affect proliferation, differentiation and apoptosis different cell types. The present study was undertaken investigate induced growth inhibition its influence on matrix metalloproteinase MMP-9 MMP-2 activities leukemia K562 HL-60 cells vitro. results revealed that expression detectable two kinds cells; Both 15-deoxy-delta(12,14)-prostaglandin J2(15d-PGJ2) troglitazone (TGZ) significant effects these cells. These could inhibit leukemic adhesion extracellular (ECM) proteins invasion through matrigel matrix. expressions as well their gelatinolytic both were inhibited by 15d-PGJ2 TGZ significantly. We therefore conclude myeloid vitro, can ECM downregulate expressions. data suggest may serve potential anti-leukemia reagents.
