Protective effects of zinc chelation in traumatic brain injury correlate with upregulation of neuroprotective genes in rat brain.

Chelation of excessive neuronal zinc ameliorates zinc neurotoxicity and reduces subsequent neuronal injury. To clarify the molecular mechanisms of this neuroprotective effect, we used a focused cDNA array of stress-response genes with zinc chelation (calcium EDTA) in our rat model of fluid percussion brain injury at 2 h, 24 h, and 7 days after injury. In parallel experiments, we compared neuronal cell death in TUNEL-stained brain sections in traumatized rats with and without calcium EDTA treatment. Zinc chelation induced the expression of several neuroprotective genes; neuroprotective gene expression correlated with substantially decreased numbers of TUNEL-positive cells.[1]
