title: Upregulation of the pro-opiomelanocortin gene in spinal motoneurones in muscular dystrophy in mice.
abstract: Pro-opiomelanocortin (POMC) mRNA was detected in motoneurones of mice using histochemical in situ hybridization and cDNA oligonucleotide probes for the adrenocorticotropin (ACTH) 4-11 and beta-endorphin 1-8 regions of POMC. Staining for POMC mRNA was negligible in motoneurones in normal adult mice but in dystrophic mice the mRNA was present in > 60% of the ventral horn cells. It is concluded that neuropathic change in motoneurones is accompanied by upregulation of the POMC gene and synthesis of POMC-derived peptides.
