The synergistic antitumor effects of psoralidin and cisplatin in gastric cancer by inducing ACSL4-mediated ferroptosis.

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
objectiveCisplatin (DDP) is the major chemotherapeutic drug used to treat gastric cancer (GC). However, DDP-associated side effects and resistance chemoresistance have limited its clinical application. Psoralidin (PSO) is the main extract of Psoralea corylifolia and has antitumor effects. The present study is designed to investigate the antitumor functions and mechanisms of PSO and DDP in GC.
methodsGC cells (HGC-27 and MKN-45 cells) were treated with PSO (2.5 to 120 µM) and/or DDP. A CCK-8 assay, colony formation assay, and EdU staining were used to test cell proliferation. Cell migration and invasion were tested via a transwell assay. An in vivo assay in nude mice was carried out to analyze the influence of PSO and DDP on tumor growth. H&E staining was conducted to test the histopathological changes of organs and tumor tissues. Ferroptosis-associated indicators, including GSH, MDA, Fe
resultsPSO impeded GC cell proliferation, migration, invasion, and growth in vivo. PSO exhibited no significant toxic effects on organs and mitigated DDP-mediated liver and kidney injuries. The combination of PSO and DDP exhibited enhanced inhibitory functions. PSO and DDP can significantly promote GC cell ferroptosis. Moreover, PSO promoted ACSL4 expression and suppressed GPX4, AIFM2, and SLC7A11.
conclusionThe combination of PSO and DDP has synergistic antitumor effects on GC cells by inducing ACSL4-mediated ferroptosis. PSO may serve as a nontoxic adjuvant to enhance DDP's efficacy and reduce side effects in GC.
