| Inhoud: |
In Tetrahymena thermophila, the ultradian rhythm of tyrosine aminotransferase activity was investigated under free-running conditions. The rhythm persisted in the presence of 1 mM emetine, although the drug efficiently inhibited both protein synthesis and cell division. Also 250 mM hydroxyurea, which suppressed cell growth to a high degree, did not prevent the rhythm. These data support the concept of an ultradian oscillator working independently of translation and being not a consequence of the “cell cycle”;, although under normal physiological conditions the rhythm of tyrosine aminotransferase is accompanied by and equiperiodic with the rhythm of cell division, both in the ultradian and circadian growth modes. |
