title: Adenovirus-mediated gene transfer of Bcl-xL impedes neurite regeneration in vitro.
abstract: Mouse retinal explants were transfected with recombinant adenovirus vector carrying the green fluorescent protein (GFP) gene and the rat bcl-x(L) gene (Adeno-Bcl-xL) to determine its ability to protect retinal ganglion cells against apoptotic cell death and to promote retinal ganglion cell neurite regeneration. Adeno-Bcl-xL-incubated retinas had reduced apoptosis compared with controls. However, neurite regeneration in adeno-treated retinas was less than that of vector-free retina. These results suggest that the usefulness of adenovirus vectors for gene therapy for retinal ganglion cells may be limited.
