Figure 4 PSGL-1 protein expression in RAW 264.7 cells after being treated with a combination of decaffeinated coffee and green tea extract for 24 hours and Ox-LDL 8 μg/mL for the next 20 hours. (a) Western blot for each group and β-actin. (b) Quantitative calculation of β-actin relative PSGL-1 protein using ImageJ. *P < 0.05 for group N. ^P < 0.05 to group C(+). #P < 0.05 to group P1.
