Kaji-Ichigoside F1 and Rosamultin Protect Vascular Endothelial Cells against Hypoxia-Induced Apoptosis via the PI3K/AKT or ERK1/2 Signaling Pathway

Figure 12

Schematic diagram depicting the cytoprotective effects of Kaji-ichigoside F1 and Rosamultin on hypoxia-induced apoptosis of EA.hy926 endothelial cells. Hypoxia causes mitochondrial apoptosis through activation of caspase-3. Rosamultin inhibits apoptosis induced by hypoxia by activating PI3K/AKT and ERK1/2 signaling pathways in EA.hy926 endothelial cells. Kaji-ichigoside F1 inhibits apoptosis via ERK1/2 signaling pathway activation. The PI3K/AKT signaling pathway positively regulates ERK1/2 and NF-κB signaling pathways, while ERK1/2 signaling positively regulates NF-κB signaling and negatively regulates the PI3K/AKT signaling pathway.
