Apigenin Protects Against Cisplatin-Induced Cardiotoxicity: Potential Involvement of CD38-Sirt3 Signaling in Rats.
Article in Molecules (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
backgroundCisplatin-induced cardiotoxicity is associated with oxidative stress, inflammation, and apoptosis; however, the role of CD38-Sirt3 signaling remains unclear. This study investigated whether apigenin protects against cisplatin-induced cardiac injury via modulation of CD38-Sirt3 signaling.
methodsMale Sprague Dawley rats were assigned to three groups, (1) Control, (2) Cisplatin (5 mg/kg), and (3) Pretreatment with apigenin (50 mg/kg/day) plus cisplatin groups. Then, left ventricular (LV) function, cardiac injury, oxidative stress, inflammation, apoptosis, and CD38-Sirt3 signaling-related proteins were assessed.
resultsCisplatin impaired LV function and induced cardiac injury, oxidative stress, inflammation, and apoptosis in rats. These changes were accompanied by increased cardiac CD38 and decreased cardiac Sirt3 and SOD2 expression. Apigenin significantly improved LV function (%LVEF and %LVFS), reduced cardiac injury (LDH, CK-MB), attenuated oxidative stress, suppressed inflammatory responses (TNF-α, IL-1β, p-NF-κB, TLR-4), and inhibited apoptosis (Bax/Bcl-2, cleaved caspase-3). Notably, apigenin improved cardiac SOD2 expression and reversed the alteration of CD38-Sirt3 signaling in cisplatin-treated rats.
conclusionsThis study provides evidence that cisplatin-induced cardiotoxicity is associated with alterations in CD38-Sirt3 signaling. Apigenin attenuated LV dysfunction and cardiac injury, reduced oxidative stress, inflammation, and apoptosis, potentially through CD38-Sirt3 signaling. These findings highlight the cardioprotective potential of apigenin against cisplatin-induced cardiotoxicity.
