Abstract

Recovery of cardiac function is the holy grail of heart failure therapy yet is infrequently observed and remains poorly understood. In this study, we performed single-nucleus RNA sequencing from patients with heart failure who recovered left ventricular systolic function after left ventricular assist device implantation, patients who did not recover and non-diseased donors. We identified cell-specific transcriptional signatures of recovery, most prominently in macrophages and fibroblasts. Within these cell types, inflammatory signatures were negative predictors of recovery, and downregulation of RUNX1 was associated with recovery. In silico perturbation of RUNX1 in macrophages and fibroblasts recapitulated the transcriptional state of recovery. Cardiac recovery mediated by BET inhibition in mice led to decreased macrophage and fibroblast Runx1 expression and diminished chromatin accessibility within a Runx1 intronic peak and acquisition of human recovery signatures. These findings suggest that cardiac recovery is a unique biological state and identify RUNX1 as a possible therapeutic target to facilitate cardiac recovery.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Previous and concurrent work highlighted the functional role of this gene regulatory network in cardiac fibrosis.

    “Indeed, previous and concurrent work has highlighted the functional role of this gene regulatory network in cardiac fibrosis28–30.”

    From Targeting immune–fibroblast cell communication in heart failure (2024) · cites this paper as [29]

    In Results (‘RUNX1 GRN is associated with recovery’; page unavailable), the paper reports that simulated RUNX1 deletion shifts fibroblasts away from states associated with fibrosis and heart failure. This supports a proposed role for the network, but the perturbation was in silico; the paper does not establish a functional role in cardiac fibrosis experimentally. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The authors previously showed expansion of RUNX1-expressing cells in human heart failure.

    “we previously showed expansion of RUNX1-expressing cells in human HF29.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
