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.

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 acts on it

  1. Strontium exposure decreased sclerostin protein expression in primary human osteoblast cultures in the 2011 study.

Where it participates (unsigned role)

  1. Strontium ranelate induced an osteocyte-like phenotype, increased DMP1 and sclerostin mRNA and markedly increased mineralization at reported concentrations of 5 mM or greater.
