Description:
Northern blot analysis of total RNA and polyadenylated RNA isolated from adult rat testes showed that a proopiomelanocortin (POMC)-like messenger RNA molecule is present in these extracts. The testicular POMC messenger RNA is comparable in length to amygdala and midbrain POMC messenger RNA and appears to be at least 200 nucleotides shorter than POMC messenger RNA found in the hypothalamus and anterior and intermediate lobes of the pituitary gland. Hybridization in situ showed that POMC messenger RNA is located in Leydig cells, which are the only testicular cells that contain immunostainable POMC-derived peptides. These results suggest that local synthesis of POMC occurs in the testis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pintar, J E -- Schachter, B S -- Herman, A B -- Durgerian, S -- Krieger, D T -- HD-18110/HD/NICHD NIH HHS/ -- HD-18592/HD/NICHD NIH HHS/ -- NB-02893-15/NB/NB NIH HHS/ -- New York, N.Y. -- Science. 1984 Aug 10;225(4662):632-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6740329" target="_blank"〉PubMed〈/a〉
