Epigallocatechin gallate prevents oxidative-stress-induced death of mutant Cu/Zn-superoxide dismutase (G93A) motoneuron cells by alteration of cell survival and death signals.

Abstract excerpt

This study was undertaken to evaluate the effect of the G93A mutation in the human Cu/Zn-superoxide dismutase gene (hSOD1) on the phosphatidylinositol-3-kinase (PI3K)/Akt and glycogen synthase kinase-3 (GSK-3) pathway in motoneuron, and to determine the role of epigallocatechin gallate (EGCG) on oxidative stress-injured motoneurons. The viability of G93A mutant cells was less than that of wild-type cells, and the...
