The Claim
In wild-type mice, PER1 protein expression in thyroid and parathyroid follicular cells peaks during the night (ZT20–ZT24), exhibiting a phase delay relative to Per1 mRNA, and shows a similar but earlier oscillation in VPAC2 receptor-deficient mice, suggesting post-transcriptional regulation of the circadian clock in these endocrine tissues.
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.
In mice, a clock-related protein in certain hormone cells turns on at night, and this timing shifts when a specific receptor is missing — meaning the body might fine-tune its internal clock after genes are read.

PER1 protein expression in thyroid and parathyroid follicular cells of wild-type mice peaks during the night (ZT20–ZT24), with a phase delay relative to Per1 mRNA, and shows a similar but earlier oscillation in VPAC2 receptor-deficient mice, indicating post-transcriptional regulation of the circadian clock in these endocrine tissues.
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 the PER1 protein in mouse thyroid cells peaks at night, after the gene turns on, and this pattern shifts earlier in mice missing a specific receptor, which supports the idea that the timing is controlled after the gene is read.
