Vaspin inhibits ferroptosis: A new hope for treating myocardial ischemia-reperfusion injury.
Article in CytoJournal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Objective: Myocardial ischemia-reperfusion injury (MIRI) is a critical pathological basis for cardiovascular diseases. In recent years, the effect of ferroptosis on MIRI has attracted extensive attention. Vaspin, an adipose tissue-derived serine protease inhibitor, has multiple biological functions, including anti-inflammatory and antioxidant effects. This study aims to investigate the molecular mechanism by which vaspin alleviates MIRI by regulating hypoxia-inducible factor-1α (HIF-1α) and ferroptosis signaling pathways. Material and Methods: A mouse model of myocardial ischemia/reperfusion (I/R) and a hypoxia/reoxygenation (H/R) model was used to evaluate the protective effects of vaspin on MIRI. The mechanism by which ferroptosis is modulated by the vaspin/HIF-1α signaling pathway was investigated by constructing a vaspin overexpression adenoviral vector. Myocardial infarct size and histological changes were assessed using triphenyltetrazolium chloride and hematoxylin-eosin staining. Ferroptosis-related proteins were detected by Western blot assay, and apoptosis and reactive oxygen species levels were analyzed by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling. Iron content in myocardial tissue and cells was measured by enzyme-linked immunosorbent assay. Results: Myocardial I/R increased myocardial infarct size and serum lactate dehydrogenase (LDH) levels compared with the control group, indicating severe myocardial injury. Western blot results showed that MIRI reduced endogenous vaspin and HIF-1α levels and inhibited glutathione peroxidase 4. Conclusion: Vaspin inhibits ferroptosis and upregulates the HIF-1α signaling pathway to mitigate myocardial I/R injury. The vaspin/HIF-1α pathway could be a potential target for MIRI prevention and treatment and offers fresh perspectives on ischemic heart disease management. Vaspin could be a novel cardioprotective agent that plays a significant role in the prevention and treatment of cardiovascular diseases.
