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

Figure 6

NBP regulated the PI3K/AKT/FoxO3a pathway in human OA chondrocytes. (a, b) The protein expressions of FoxO1, FoxO3a, p-FoxO3a, FoxO4, PI3K, p-PI3K, AKT, and p-AKT were determined by Western blot assay. (c–e) The mRNA levels of FoxO1, FoxO3a, and FoxO4 were measured using qRT-PCR. (f) Immunofluorescence staining of FoxO3a and ACTIN (scale bar, 20 μm). All data are expressed as the (SD). .
