Expression of genes associated with lipid accumulation, extracellular matrix synthesis and fibrosis, and inflammation. The expression of each gene was normalized to β-actin and further normalized to the vehicle group. Values are mean±SD. N=10 for each group. *Significantly different from vehicle group (P<0.05). PPARγ, peroxisome proliferator-activated receptor γ; cEBPα, CCAAT/enhancer binding protein α; CD36, cluster of differentiation 36/fatty acid transporter; Col1α2, type I collagen α2; Col3α1, type III collagen α1; MMP, matrix metalloproteinase; TIMP, tissue inhibitor of metalloproteinase; FSP1, fibroblast specific protein 1; COX, cyclooxygenase; IL, interleukin.
