title: Localization by immunohistochemistry of renal ornithine decarboxylase in the mouse with and without testosterone treatment.
abstract: The immunohistochemical distribution of renal ornithine decarboxylase was studied in male mice both with and without testosterone treatment. Testosterone (1 mg per mouse) induced a marked increase in ornithine decarboxylase activity of the mouse kidney, whereas no significant immunohistochemical difference was observed either in immunoreactivity or its localization. In intact male as well as androgen-treated mice dense ornithine decarboxylase-immunoreactive cells were observed mainly in the cortex, especially many ornithine decarboxylase-immunoreactive cells were observed in the inner portion, while a much weaker immunoreactivity was observed in the medulla. The largest number of ornithine decarboxylase-immunoreactive cells seemed to be localized in the pars recta of the proximal tubule. The immunoreactivity was not detected in all the tubular cells but scattered among them. The renal corpuscles were not immunoreactive. In each ornithine decarboxylase-immunoreactive cell, the cytoplasm showed much denser immunoreactivity than the nucleus.
