Figure 9. The effects of PSP on AKT and
ERK1/2 signaling. The protein expression of phosphorylation and total
AKT and ERK1/2 were assessed using total cellular protein lysates. PSP
significantly reduced the level of phosphorylation of both AKT and
ERK1/2 in HUVECs, although it had no effect on the total amount of AKT
or ERK1/2 protein.
