Role of Gap Junction in Retina Circadian Rhythms: Gap junction blockade disrupts circadian regulation of gene expression in embr,Used
Delivery time: 8-12 business days (International)
The hypothesis was gap junction communication also plays a role in coordinating transcript rhythms of the circadianregulated genes in chicken retina. To test this hypothesis, a chicken embryonic retinal explant culture was established. The robust, selfsustaining, and lightentrainable iodopsin and Arylalkylamine Nacetyltransferase (AANAT) mRNA rhythms were observed under different lighting conditions. This observation supports use of the explant cultures to test effects of gap junction blockers on gene expression rhythms in retina. The two reversible gap junction blockers, 18alphaglycyrrhetnic acid3hemisuccinate and 18betaglycyrrhetnic acid, were applied to the explant cultures. Both blockers produced a rapid and persistent reduction in iodopsin and AANAT mRNA levels. Upon removal of the blockers, the transcript rhythms of both genes reappeared within a 24 hrs. These data suggest that the change in iodopsin mRNA levels was not due to disruption of function or phase of the circadian oscillators driving the transcript rhythms. The blockers may either uncouple the circadian oscillators and the transcription of these two genes or alter stability of both transcripts.
