Component
Human sclerostin / SOST
Context-specific entity; species, compartment and exposure are stated on each claim.
3 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
Strontium exposure decreased sclerostin protein expression in primary human osteoblast cultures in the 2011 study.

## strontium-human-sclerostin Removing a Wnt inhibitor can favor a bone-cell response. Strontium exposure decreased sclerostin protein expression in primary human osteoblast cultures in the 2011 study. Model: Human primary osteoblast culture. Limitations: Separate from the Akt branch; an earlier long-term culture report found increased SOST mRNA with an osteocyte-like phenotype. Protein, RNA, stage and time are not interchangeable. Evidence access: Primary abstract An Akt-dependent increase in canonical Wnt signaling and a decrease in sclerostin protein levels are involved in strontium ranelate-induced osteogenic effects in human osteoblasts. · 2011 · https://pubmed.ncbi.nlm.nih.gov/21566129/ · DOI 10.1074/jbc.M111.251116

Where it participates (unsigned role)
Strontium ranelate induced an osteocyte-like phenotype, increased DMP1 and sclerostin mRNA and markedly increased mineralization at reported concentrations of 5 mM or greater.
Experimental context and source evidence

- Long-term adult human primary osteoblast cultures.

- High culture concentration; SOST transcript increase is not a direct contradiction of a different study measuring sclerostin protein.
