Effects of lentivirus-mediated astrocyte elevated gene-1 overexpression on proliferation and apoptosis of human retinoblastoma cells.

A lentivirus-mediated AEG-1 overexpression in RB cells led in vitro to a growth promotion and an apoptosis inhibition of human RB cells, associated with an upregulation of the Bcl-2 protein, a downregulation of the Bax protein and of cleaved caspase-3 proteins, and with alterations of the cell cycle. AEG-1 may be involved in the development and progression of RB.
