Description:
When chicken pineal glands were organ-cultured in darkness, serotonin N-acetyltransferase activity was low during daytime, increased at midnight, and decreased on the next morning. The autonomous increase of N-acetyltransferase activity was suppressed by illumination of the glands. When pineal glands were cultured under a light-dark cycle (LD 12:12), the change of N-acetyltransferase activity continued to oscillate in phase with the light-dark cycle for 3 days.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Deguchi, T -- New York, N.Y. -- Science. 1979 Mar 23;203(4386):1245-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424750" target="_blank"〉PubMed〈/a〉
