Cu/Zn- and Mn-Superoxide Dismutase Distribution and Concentration in Adrenal Tumors

These data suggest that the localization of Cu/Zn- and Mn-SODs in adrenal tissues reflects the specificity of the adrenal cells that produce the tissue-specific hormones. An investigation of changes in these enzymes in adrenal tumors may also provide useful information on adrenal tumor cell differentiation.
