ROS are highly expressed in LECs during the onset of diabetic cataracts stimulated by high glucose [18, 21], and could induce EMT by activating several transcription factors, such as Snail, STAT3, and ZEB1, which can be activated by the Notch, G-CSF, MAPK, and PI3K/Akt signaling pathways in cancer cells [47]. Here, AKT1 is linked to cancer.
