ABSTRACT
Objective: To observe the level of pro-opiomelanocortin (POMC) mRNA expression in the hypothalamic arcuate nucleus in young and senile rats. Methods: POMC mRNA was determined with in situ hybridization, the hybridization signals and areas of POMC mRNA-positive cells were measured with computer image analysis system. Results: Compared with young rats, average gray values of POMC mRNA-positive neurons in the hypothalalmic arcuate nucleus and near region in the senile rats decreased, but the numbers of POMC mRNA-positive neurons did not change significantly. Conclusion: The decrease of POMC mRNA expression level in individual neurons in hypothalamic arcuate nucleus of senile rats is one of the causes that decrease the expression of peptides-derived from POMC gene.
