چکیده انگلیسی
Peroxisome proliferator-activated receptor γ (PPAR-γ) is a nuclear hormone receptor that is involved in a wide range of cellular processes. Although it is known that PPAR-γ plays an important role in cell cycle control, inflammation, apoptotic cell death, and other cellular processes, the role of PPAR-γ in the normal and pathological function of growth plate chondrocytes has not been investigated. The purpose of this study was to determine if PPARs are expressed in growth plate chondrocytes and to describe the biological effect of PPAR activation in these cells. The results demonstrate the presence of three PPAR isoforms (α, δ, and γ) in growth plate cartilage. Activation of PPAR-γ by ciglitazone in growth plate chondrocytes inhibits T3 induced terminal differentiation and promotes apoptosis through increased levels of caspase 3/7 activity and decreased expression of the anti-apoptotic protein Bcl-2.
