Effect of Aβ protein on inhibiting proliferation and promoting apoptosis of retinal pigment epithelial cells.

ABSTRACT:

Aim

To identify the effect and regulatory mechanism of amyloid β (Aβ) protein on retinal pigment epithelial (RPE) cells in cell proliferation and apoptosis, and clarify Aβ role in the pathogenesis of age-related macular degeneration (AMD).

Methods

The model of Aβ25-35 protein cytotoxicity in RPE cell was successfully established to investigate the effect of Aβ protein on RPE cells in vitro. Based on Aβ protein, the specific inhibitors (HY-50682 or BAY11-7082) or activating agent (lipopolysaccharide) was used to analyze the regulatory mechanism of Aβ protein to RPE cells on cell proliferation and apoptosis by flow cytometry, real-time polymerase chain reaction, Western blotting, enzyme-linked immunosorbent assay and dual-luciferase reporter gene assay.
