Aortic valve-specific genes dysregulated in calcific aortic valve stenosis as potential biomarkers and therapeutic targets
Bibliographic record
Abstract
Calcific aortic valve stenosis (CAVS) is the most frequent heart valve disease. Elucidating specific gene expression patterns in the aortic valve could provide new insights for understanding disease pathophysiology. We used local RNA sequencing data from 500 explanted human aortic valves to identify aortic valve-specific genes and compared their expression according to disease status and CAVS severity. We identified 100 specific protein-coding genes in the aortic valve compared to 45 other tissues from the Genotype-Tissue Expression (GTEx) project. Among them, 38 were differentially expressed in CAVS. Ten had a gradient of expression between severity levels and were central in a protein-protein interaction network, most of which were involved in extracellular matrix regulation or inflammation. Among the aortic valve-specific genes, four of the corresponding proteins had a significantly different plasma level in individuals with CAVS. These findings represent a robust foundation for the development of specific biomarkers and therapies for CAVS.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
