DL-3-N-Butylphthalide Promotes Cartilage Extracellular Matrix Synthesis and Inhibits Osteoarthritis Development by Regulating FoxO3a

Figure 7

NBP increases ECM anabolism in human OA chondrocytes by regulating FoxO3a. (a, b) The protein and mRNA levels of FoxO3a were evaluated by Western blot and qRT-PCR after treated with and/or Lv-FoxO3a for 24 h. (c) Proteins expressions of ACAN and COL2A1 were detected by Western blot. (d) Immunofluorescence staining for COLII (scale bar, 50 μm). (e–h) The mRNA levels of COL2A1, ACAN, SOX9, and PRG4 were determined by qRT-PCR. All data are expressed as the (SD). .
