Arvanil reverses cisplatin resistance in ovarian cancer by activating HMOX1-driven ferroptosis.
Article in Scientific reports, 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
Cisplatin resistance limits the effectiveness of ovarian cancer (OC) therapy. Arvanil is a synthetic capsaicin derivative with favorable pharmacokinetic properties. This study showed that Arvanil enhances the anti-tumor effect of cisplatin in cisplatin-resistant ovarian cancer cells, partly associated with HMOX1-related ferroptosis. The combination treatment elevated reactive oxygen species (ROS), lipid peroxidation (LPO), and ferrous ion (Fe²⁺) levels, suppressed GPX4 protein expression, and activated multiple key ferroptosis regulators. Inhibition of HMOX1 partially reversed these effects, confirming its pivotal regulatory role. In vivo experiments further validated the synergistic anti-tumor efficacy of the Arvanil-cisplatin combination, with no significant changes in body weight and no apparent histopathological or serum biochemical abnormalities detected under the tested conditions. This study provides a novel strategy to overcome cisplatin resistance and expands the potential application of small-molecule ferroptosis inducers in cancer therapy.
