Andrographolide Protects against HG-Induced Inflammation, Apoptosis, Migration, and Impairment of Angiogenesis via PI3K/AKT-eNOS Signalling in HUVECs

Figure 5

Graphical abstract. Andrographolide (Andr) attenuates HG-induced vascular endothelial dysfunction. Andr increases the expression of P-PI3K, P-AKT, and P-eNOS that was inhibited by HG, thus suppressing the gene expression of IL-1β, IL-6, and TNFα and the expression of VEGF. Furthermore, this effect inhibits HUVECs and promotes tubule formation, consequently decreasing the levels of LDH and MDA induced by HG.
