| Outline of Final Research Achievements |
Vascular cell death causes diabetic retinopathy and autophagy has been paid attention as a novel cell death mechanism. We compared gene expression between low and high glucose - stimulated vascular endothelial cells. High glucose-stimulation induced inflammatory and thrombotic effects in gene expression profile in vascular cells. TGFB2 specially upregulated and mediated cell death. High glucose condition upregulated autophagy and inhibited TNF-induced P62 increase, which are reversed by inhibition of autophagy reflux. These finding suggests that autophagy regulation could be applied to future treatment strategies.
