Matrix metalloproteinases: control of vascular function and their potential role in preeclampsia
Bibliographic record
Abstract
Preeclampsia is a pregnancy specific disorder characterised by hypertension and proteinuria occurring after the twentieth week of gestation. Preeclampsia induced hypertension is the result of increased vascular reactivity and endothelial dysfunction, however, the mechanisms underlying this state remain elusive. One possible mediator may be the matrix metalloproteinases (MMPs), a family of proteinases typically recognized for long term tissue remodelling. This review examines the evidence suggesting a role for MMPs in acutely regulating vascular function. Studies have shown that MMPs can activate vasoconstrictors (e.g. endothelin), inactivate vasodilators (e.g. calcitonin gene related peptide) and transactivate cell surface receptors responsible for vasoconstriction (e.g. epidermal growth factor receptor). The potential role of these proteinases in preeclampsia will then be discussed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
