[Retracted] Effects of Ruanmailing in Blocking Early Stages of Atherosclerosis by TNF-α Regulation via Kir2.1

Figure 4

Detection of Kir2.1 and TNF-α protein expression. (a) TNF-α protein expression increased significantly after the formation of macrophage foam cells. (b) Kir2.1 and TNF-α protein expression levels decreased after treatment with serum containing different concentrations of Ruanmailing, and the differences were statistically significant. ImageJ was used for the quantitative analysis (^∗P < 0.05). Group A: macrophage control, Group B: macrophage foam cell, Group C: low-concentration Ruanmailing, Group D: medium-concentration Ruanmailing, Group E: high-concentration Ruanmailing.
