As shown in Figures 4(a) and 4(b), OGD/R treatment apparently decreased the ratio of phosphorylated Akt (p-Akt)/Akt and phosphorylated mTOR (p-mTOR)/mTOR, whereas both the ratio of p-Akt/Akt and p-mTOR/mTOR increased in the presence of OM-MSCs relative to those after OGD/R intervention. Here, AKT1 is linked to ocular melanoma.
