Component
Rat cardiomyocyte PDH phosphorylation
Study-specific entity. Experimental conditions and evidence limits remain on each linked claim.
1 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 acts on it
PDK4 overexpression increased PDH phosphorylation in neonatal rat cardiomyocytes.
Experimental context and source evidence
- access_level
- full_text_and_supplement_review
- compartment
- Mitochondria or cell lysate, depending on assay
- dose
- Adenovirus MOI 50:1 where applicable; compound concentrations not specified in reviewed methods
- duration
- Adenovirus incubation 6–8 h; subsequent endpoint timing not consistently specified
- endpoint
- rat-pdh-phosphorylation
- evidence_location
- Supplementary Figure S8C/D
- experimental_model
- Adenoviral/cell perturbation study
- exposure
- rat-pdk4-overexpression
- limitations
- Single primary study; not independently replicated here. Cardiac and recombinant findings do not establish pulmonary endothelial, viral-sepsis or ARDS effects. Phosphorylation is not a direct PDH flux measurement. Peer-review response wording and panel labels are inconsistent; retain the main-text assignment with this qualification.
