The results showed that, after 72 h of GPS infection, the phosphorylation of PI3K (p-PI3K/PI3K) in the GPS-infected group was significantly decreased (p < 0.01), as was the phosphorylation of Akt and Erk (p-Akt/Akt and p-Erk/Erk) (p < 0.05) compared to the control group (Figure 6C). Here, AKT1 is linked to infection.
