The Components of Flemingia macrophylla Attenuate Amyloid β-Protein Accumulation by Regulating Amyloid β-Protein Metabolic Pathway

Figure 5

The level of IDE was differentially affected by the fractions and flavonoids of F. macrophylla. N2a cells were treated with fractions and flavonoids for 20 h at NTC. The level of IDE in cell lysate and medium was determined by immunoblotting. The upper panel is the representative blot. The lower panel is the relative level of IDE in cell lysate (closed column) and medium (opened column) exhibited as percentage of the control. Results are means ± SD from three independent experiments. Significant differences between control and the treated cells are indicated by *𝑃<0.05, **𝑃<0.01 and ***𝑃<0.001.
