The Claim
Murine cells fail to up-regulate the CAMP gene in response to 1,25-dihydroxyvitamin D3, and CAMP mRNA expression in vitamin D receptor-deficient mouse bone marrow is comparable to that in wild-type mice, demonstrating a species-specific difference in vitamin D-mediated regulation of the CAMP antimicrobial gene.
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, vitamin D doesn’t turn on a key germ-fighting gene the way it does in humans—so even when the vitamin D signal is present or missing, the gene stays quiet. This means mice and humans respond differently to vitamin D when it comes to fighting infections.
See the scientific wording
Murine cells do not up-regulate the CAMP gene in response to 1,25-dihydroxyvitamin D3, and CAMP mRNA expression in vitamin D receptor-deficient mouse bone marrow is similar to wild-type levels, indicating a species-specific difference in vitamin D regulation of this antimicrobial gene.
What the research says
1 studyIn humans, vitamin D turns on a gene that helps fight germs, but in mice, it doesn’t — because mice lack the genetic switch that lets vitamin D do that. This study proves the difference is real and built into their DNA.
