GADD34 is expressed in the ischaemic brain and reverses protein synthesis shutdown. Consequently, GADD34 could have neuroprotective potential in stroke. BHK medium, a replication-deficient HSV viral vector (HSV1716) with no insert or containing full-length GADD34, the N terminal or a conserved portion of the gene, was injected into mouse brain before stroke. Infarct size was 1.0±0.26, 1.19±0.36, 1.5±0.36, 1.3±0.36, and 1.1±0.28 mm
3 , respectively. The increase in infarct size with full-length GADD34 was statistically significant (P<0.05). Immunohistochemistry confirmed viral protein expression. Tissue culture studies revealed GADD34 gene restored virulence in HSV1716, suggesting that HSV virulence, rather than increased GADD34, exacerbated ischaemic damage.Journal of Cerebral Blood Flow & Metabolism (2008) 28, 747–751; doi:10.1038/sj.jcbfm.9600565; published online 10 October 2007 [ABSTRACT FROM AUTHOR]- Published
