The distribution of ornithine decarboxylase antizyme messenger ribonucleic acid (AZ mRNA) and AZ-like immunoreactivity (LI) was studied in the brainstem and spinal cord motoneurons and in the extraocular and triceps surae muscles of rat. In situ hybridization showed AZ mRNA in the gray matter of the spinal cord at different levels of spinal cord with highest AZ mRNA levels in the ventral horn of the spinal cord. No apparent changes in AZ mRNA contents were seen after unilateral transection of the sciatic nerve in lumbar motoneurons. AZ-immunoreactive (IR) motoneurons were observed in the nucleus of the VI cranial nerve and in the ventral horn of the spinal cord. These motoneurons also showed ornithine decarboxylase (ODC)-LI. Subcellularly, AZ-LI was observed both in the nuclei and cytoplasm of labeled motoneurons. Heavily stained AZ-IR nerve fibers and myoneural junctions were observed among muscle fibers in different muscles. In addition, the nuclei of muscle fibers showed AZ-LI.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012333	RNA, Messenger	RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
