Myc overexpression improves recovery from myocardial infarction associated with cardiomyocyte hyperplasia in the mouse heart.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Adult mammalian hearts lack the ability to regenerate after a myocardial infarction, which leads to heart failure progression. Therefore, finding ways to promote regeneration is a major goal in the development of cardiovascular therapies. In this study, we focus on the role of Myc moderate overexpression in response to acute ischemic injury. We have previously shown that moderate Myc overexpression is not detrimental to cardiac function and promotes cell competition and a hyperplastic phenotype. Here, we describe that Myc overexpression in non-regenerative postnatal hearts promotes functional improvements and reduced scar formation after myocardial infarction. This response correlates with a hyperplastic phenotype in postnatal and adult hearts, characterized by bigger hearts, smaller cardiomyocyte size and increased BrdU incorporation without ploidy increase. Moreover, we show that Myc strongly enhances diploid cardiomyocyte proliferation and the generation of new binucleated cardiomyocytes. Thus, Myc promotes functional and morphological improvements in the heart following acute ischemia and this response correlates with promotion of hyperplasia versus hypertrophy.
