Apelin-13 Is an Early Promoter of Cytoskeleton and Tight Junction in Diabetic Macular Edema via PI-3K/Akt and MAPK/Erk Signaling Pathways
Figure 6
Apelin induces the expression of cytoskeleton and tight junction proteins in C57/BL6 mice via PI-3K/Akt and MAPK/Erk signaling pathways. (a–e) The western blot results found that the expression of APJ and the phosphorylation of cytoskeleton (VE-Cadherin and FAK) and tight junction proteins (occludin and ZO-1) increased significantly in apelin-treated (10 and 100 ng/ml) C57BL/6J mice. (f–h) The phosphorylation of PI-3K/Akt and MEK/Erk signaling pathways, p38, Akt, and Erk also increased significantly. Protein intensity was quantified by Image J software and expressed as fold of change relative to control (mean ± SD, ). , versus control one, Student’s -test.
