abstract = {Genetic manipulation of cells and tissue by RNA
interference has significantly contributed to the functional
characterization of individual proteins and their role in
physiological processes. Despite its versatility, RNA
interference can have detrimental side effects, including
reduced cell viability. We applied recombinant
adeno-associated viruses by stereotaxic injection into the
murine hippocampus to express different short hairpin RNA
(shRNA) constructs along with eGFP. Tissue responses were
assessed immunohistochemically for up to 8 weeks
post-infection. Strong hippocampal degeneration and tissue
atrophy was observed, most likely induced by high shRNA
expression. The effect was entirely absent in mice injected
with vectors driving only expression of eGFP. Active
caspase-3 (Casp-3) and glial fibrillary acidic protein
(GFAP) were identified as molecular markers and early
indicators of adverse tissue responses. Our findings also
demonstrate that detrimental effects of high shRNA
expression in hippocampal tissue can be monitored even
before the onset of tissue degeneration.},
