Kadota Y, Suzuki S, Ideta S, Fukinbara Y, Kawakami T, Imai H, Nakagawa Y, Sato M: Enhanced metallothionein gene expression induced by mitochondrial oxidative stress is reduced in phospholipid hydroperoxide glutathione peroxidase-overexpressed cells. Eur J Pharmacol. 2010 Jan 25;626(2-3):166-70. Epub 2009 Oct 8.
The enhanced expression of metallothionein-I and metallothionein-II mRNA in rotenone-treated control cells was significantly decreased in rotenone-treated PHGPx-ov cells, suggesting that the hydrogen peroxide that is formed by superoxide anions generated in mitochondria diffuse into the cytosol and induce metallothionein mRNA expression. |
