Emodin protects against severe acute pancreatitis-associated acute lung injury by activating Nrf2/HO-1/GPX4 signal and inhibiting ferroptosis in vivo and in vitro.
Article in BMC gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundSevere acute pancreatitis (SAP) has high morbidity, a complicated and dangerous course, and many complications, including severe pulmonary complications. SAP-associated acute lung injury (SAP-ALI) is still a significant challenge for surgeons because of its high mortality. Therefore, more effective treatment methods are urgently needed. Emodin (EMO) has shown tremendous potential in treating many refractory diseases. However, its protection mechanism in SAP-ALI needs to be further clarified. This study was undertaken to investigate the protective effects of EMO against lung injury in SAP rats and alveolar epithelial cells, with a particular focus on the classical ferroptosis pathway.
methodsIn an in vivo study, forty SD rats were evenly split into five groups: sham operation (SO) group, the biliopancreatic duct was retrogradely injected with 5% sodium taurocholate (STC) to create the SAP group, SAP + EMO group was administered EMO via gavage to the rats following the modeling, SAP + ML385 group (a given inhibitor of nuclear factor erythroid 2-related factor 2 (Nrf2)), SAP + ML385 + EMO group. In an in vitro study, alveolar epithelial A549 cell lines were exposed to lipopolysaccharide (LPS) and treated with EMO. ML385 was also used to inhibit the expression of Nrf2. Pancreatic and lung tissue damage was evaluated using histological examination and molecular experiments. Enzyme-linked immunosorbent assays (ELISA) were used to assess the levels of pro-inflammatory cytokines, Fe
resultsThe findings demonstrated that suppressing Nrf2 expression exacerbated the inflammatory response brought on by SAP and the pathological alterations of SAP-ALI. Emodin treatment reversed this pathological change by activating the Nrf2/Heme Oxygenase-1 (HO-1)/glutathione peroxidase 4 (GPX4) signal path. Moreover, these results also showed that EMO, contrary to the effects of ML385, suppressed the ferroptosis response, which manifested as up-regulated glutathione (GSH) and GPX4 levels in vivo and in vitro and down-regulated malondialdehyde (MDA), superoxide dismutase (SOD), Fe
conclusionsOur results demonstrated that EMO effectively inhibited ferroptosis both in vivo and in vitro, while also modulating the Nrf2/HO-1/GPX4 signaling pathway to provide protection against SAP-ALI.
