Baicalin improves isoproterenol-induced cardiac remodeling by regulating the Nrf2-dependent signaling pathway.
Article in BMC cardiovascular disorders, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCardiovascular disease carries the highest mortality rate among diseases, and pharmacological interventions have limited efficacy. Baicalin (Bai) promotes biological metabolic processes, eliminates oxygen free radicals, and is anti-inflammatory. This study aimed to investigate the effect of Bai on the cardiac injury model induced by isoproterenol in mice. METHODS AND
resultIn this study, all groups except the control received intraperitoneal injections of isoproterenol (ISO) to induce a cardiac injury model, with the drug administered continuously for 14 days. hematoxylin and eosin staining and Masson's trichrome staining revealed that Bai significantly mitigated ISO-induced pathological changes in mouse heart tissue and alleviated myocardial hypertrophy. Echocardiography assessments demonstrated that Bai preserved cardiac function in ISO-treated mice. Furthermore, our findings indicated that Bai activated the Nrf2 signaling pathway in vivo and in vitro. To delve deeper, mice were further treated with ML385 (ML) via intraperitoneal injection to inhibit the Nrf2 pathway. Results showed that ML385 blocked the cardioprotective effects of Bai in mouse heart tissue.
conclusionBai protects against ISO-induced cardiac injury, and its mechanism is related to activating the Nrf2/HO-1 signaling pathway to regulate cardiac ferroptosis and improve cardiac remodeling.
