SIGNIFICANCE: Respiring mitochondria are a significant site for reactions
involving reactive oxygen and nitrogen species that contribute to irreversible
cellular, structural, and functional damage leading to multiple pathological
conditions. Manganese superoxide dismutase (MnSOD) is a critical component of the
antioxidant system tasked with protecting the oxidant-sensitive mitochondrial
compartment from oxidative stress. Since global knockout of MnSOD results in
significant cardiac and neuronal damage leading to early postnatal lethality,
this approach has limited use for studying the mechanisms of oxidant stress and
the development of disease in specific tissues lacking MnSOD. To circumvent this
problem, a number of investigators have employed the Cre/loxP system to precisely
knockout MnSOD in individual tissues. RECENT ADVANCES: Multiple tissue and
organ-specific Cre-expressing mice have been generated, which greatly enhance the
specificity of MnSOD knockout in tissues and organ systems that were once
difficult, if not impossible to study. CRITICAL ISSUES: Evaluating the
contribution of MnSOD deficiency to oxidant-mediated mitochondrial damage
requires careful consideration of the promoter system used for creating the
tissue-specific knockout animal, in addition to the collection and interpretation
of multiple indices of oxidative stress and damage. FUTURE DIRECTIONS: Expanded
use of well-characterized tissue-specific promoter elements and inducible systems
to drive the Cre/loxP recombinational events will lead to a spectrum of MnSOD
tissue knockout models, and a clearer understanding of the role of MnSOD in
preventing mitochondrial dysfunction in human disease.
