Effect of EGFR activation on mouse chondrocytes
We examined the change of chondrocyte transcriptome after EGFR activation by TGF-a and inhibition by gefitinib. Data analysis showed that EGFR activation down-regulates cartilage ECM biosynthesis and promotes ECM degradation. Gefitinib can reverse the effects of EGFR on chondrocytes. Overall design: Cells: P2 mouse epiphyseal chondrocytes; Groups: Control (PBS), TGF-a (10 ng/ml, 48 h), TGF-a + Gefitinib (10 µM, 48 h)
