The IFN-beta and retinoic acid-induced cell death regulator GRIM-19 is upregulated during focal cerebral ischemia.

The induction of GRIM-19 has been shown to be essential for interferon-beta (IFN-beta)-induced and retinoic acid (RA)-induced tumor cell death. We have studied the localization and levels of GRIM-19 in IFN/RA-induced cell death in neural cells and in focal cerebral ischemia. Exposure to IFN/RA caused a approximately 15-fold increase in GRIM-19 protein levels and induced >50% cell death in human neuroblastoma SH-SY5Y cells. In rats subjected to permanent focal cerebral ischemia, increased oxidative stress, as well as increased GRIM mRNA levels (32-fold) and increased GRIM-19 (>50%) protein levels were noted in the ipsilateral (affected) hemisphere compared with the contralateral (unaffected) hemisphere. These results suggest that GRIM-19 may play a role in ischemia-induced neuronal cell death.
