Puerarin alleviates myocardial ischemia-reperfusion injury by enhancing FUNDC1-mediated mitophagy.
Article in Molecular and cellular biochemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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
Myocardial ischemia‑reperfusion injury (I/R) is a major contributor to adverse outcomes in ischemic heart disease. Mitochondrial dysfunction plays a central role in I/R, and modulating mitophagy has shown potential in attenuating such injury. Nevertheless, whether puerarin influences mitophagy during I/R remains poorly understood. An in vivo I/R (30 min/24 h) model was established in C57BL/6 mice after 7 day puerarin pretreatment. In vitro, a hypoxia‑reoxygenation H/R (8 h/4 h) model was constructed using H9c2 cardiomyocytes. Cardiac function was assessed by echocardiography, infarct size was determined via Evans Blue‑TTC staining, mitophagy was visualized by transmission electron microscopy, and expression of mitophagy‑related proteins was evaluated by western blot. Puerarin significantly reduced I/R‑induced damage in both models. It attenuated mitochondrial depolarization and reactive oxygen species generation, increased mitophagic activity, and upregulated the mitophagy receptor FUNDC1. Puerarin alleviates myocardial ischemia‑reperfusion injury by enhancing FUNDC1‑mediated mitophagy, particularly during early reperfusion. These results reveal a key mechanism underlying the cardioprotective effect of puerarin and support its further development as a therapeutic agent for I/R.
