Moreover, Western blot analysis (Figure 4G) indicated that the protein levels of p-p38 (p-p38/p38, 0.57 ± 0.03 vs 1.19 ± 0.08, p < 0.05, Figure 4H) and p-ERK1/2 (p-ERK/ERK, 0.51 ± 0.03 vs 0.98 ± 0.03, p < 0.05, Figure 4I) were significantly higher in sepsis serum-treated HUVECs than in the control group. Here, MAPK3 is linked to Sepsis.
