Figure 4: Western blotting assays for matrix metalloproteinase 2 (MMP-2) and MMP-9 in HuH28 cells. After treatment with alpha-L-fucosidase (AFU), the expression of MMP-2 and MMP-9 in HuH28 was lower than that in the phosphate-buffered saline (PBS) control and the cells treated with AFU + deoxyfuconojirimycin (DFJ).
