The Claim
In VPAC2 receptor-deficient mice under 12:12 light-dark conditions, the amplitude of Per1, Per2, and Bmal1 mRNA oscillations in the thyroid gland is approximately 50% lower compared to wild-type mice, indicating that VIP/VPAC2 signaling contributes to the robustness of circadian gene expression in this peripheral tissue.
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 weaker daily rhythms in their thyroid gland, which suggests this system helps keep the body's internal clock running strongly in that organ.
See the scientific wording
The amplitude of Per1, Per2, and Bmal1 mRNA oscillations in the thyroid gland is approximately 50% lower in VPAC2 receptor-deficient mice compared to wild-type mice under 12:12 light-dark conditions, indicating that VIP/VPAC2 signaling contributes to the robustness of circadian gene expression in this peripheral tissue.
What the research says
1 studyStudy: The Circadian Clock Is Sustained in the Thyroid Gland of VIP Receptor 2 Deficient Mice
The study found that mice without the VPAC2 receptor have weaker daily rhythms in key clock genes in the thyroid, just like the claim says, so it supports it.
