Abstract
Cardiac fibrosis can be mitigated by limiting fibroblast-to-myofibroblast differentiation and proliferation. Human antigen R (HuR) modulates messenger RNA stability and expression of multiple genes. However, the direct role of cardiac myofibroblast HuR is unknown. Myofibroblast-specific deletion of HuR limited cardiac fibrosis and preserved cardiac functions in pressure overload injury. Knockdown of HuR in transforming growth factor-β1-treated cardiac fibroblasts suppressed myofibroblast differentiation and proliferation. HuR deletion abrogated the expression and messenger RNA stability of cyclins D1 and A2, suggesting a potential mechanism by which HuR promotes myofibroblast proliferation. Overall, these data suggest that inhibition of HuR could be a potential therapeutic approach to limit cardiac fibrosis.

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
