Abstract
Heart disease, a leading cause of mortality worldwide, is in urgent need of improved therapies. Fibrosis, an accumulation of collagen-rich extracellular matrix in response to injury, is a hallmark of heart disease, but clinical agents that can interfere with the fibrotic pathway do not yet exist. Here we show that ANTXR1/TEM8, a pathology-induced transmembrane protein required for collagen removal, exacerbates injury in multiple models of heart failure. Genetic disruption of Antxr1 and treatment with human neutralizing antibodies prevented heart deterioration following acute myocardial infarction. ANTXR1 pharmacological blockade also improved heart function in models of pressure overload and obesity-induced heart disease with preserved ejection fraction. Improved heart function was accompanied by enhanced exercise tolerance. Mechanistic studies revealed an ANTXR1-antibody-driven improvement in post-infarct scar formation followed by attenuation of late-stage, chronic TGFβ-mediated extracellular matrix remodeling. Thus, ANTXR1-mediated collagen turnover during heart failure is both maladaptive and druggable, providing avenues for therapeutic intervention.

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 it
