摘要：

Haem oxygenase-l is upregulated by numerous insults, including oxidative stress, and under such circumstances it is considered to be a protective stratagem. We have measured the haem oxygenase-l expression in heart, lung and liver tissues of control and iron-overloaded rats. Lung tissue from iron-overloaded rats displayed a significant increase in the haem oxygenase-l protein but no changes in haem oxygenase-l mRNA, Conversely, heart tissue showed a significant increase in haem oxygenase-l mRNA but no changes in haem oxygenase-1 protein. We conclude that during oxidative stress caused by iron overload, lung tissue responds with a rapid upregulation of haem oxygenase-l levels. (C) 1999 Federation of European Biochemical Societies.
