Abstract/OtherAbstract:
|
Pineal expression of Cry2 mRNA has been examined in chickens under normal (LD) and reversed (DL) light-dark conditions. In vivo the peak of Cry2 mRNA content at late subjective day under LD diminished after switching to a DL schedule. In vitro, Cry2 mRNA levels showed a steady decrease during light exposure at subjective night. Our data show that light-sensitive clock components in the pinealocytes may be involved in the repression of Cry2 transcription at night, which may contribute to resetting the phase of the clock within 24 h. |
