Figure 8(b), which displays the analysis of NF-κB by a Western blot, shows that compared with that of the air-exposed control group (0.014 ± 0.001), inhalation of P-WPS induced a statistically insignificant increase of NF-κB expression (0.039 ± 0.002, P = 0.07), and a significant increase in the expression of NF-κB in the AF-WPS (0.049 ± 0.012, P < 0.05) and SF-WPS (0.057 ± 0.006, P < 0.01) groups. The gene discussed is NFKB1; the disease is atrial fibrillation.
