The Claim
In VPAC2 receptor-deficient mice under 12:12 light-dark conditions, the phase of Per1, Per2, and Bmal1 mRNA expression in the thyroid gland is advanced by approximately 5 hours compared to wild-type mice, indicating that VIP/VPAC2 signaling modulates the timing of circadian gene expression in this peripheral organ.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Mice that are missing a certain brain signaling system have their daily body clock in the thyroid gland running about 5 hours earlier than normal mice — this suggests that the signaling system helps set the clock in that organ.

The phase of Per1, Per2, and Bmal1 mRNA expression in the thyroid gland is advanced by approximately 5 hours in VPAC2 receptor-deficient mice compared to wild-type mice under 12:12 light-dark conditions, indicating that VIP/VPAC2 signaling influences the timing of circadian gene expression in this peripheral organ.
What the research says
1 studyStudy: The Circadian Clock Is Sustained in the Thyroid Gland of VIP Receptor 2 Deficient Mice
The study shows that mice missing a certain brain signaling pathway have their thyroid's daily gene rhythms shifted earlier by about 5 hours, which supports the idea that this pathway helps control the timing of the thyroid's internal clock.
