Scutellaria Barbata Water Extract Suppresses Breast Cancer Growth and Lung Metastasis by Inducing Ferroptosis.
Article in Integrative cancer therapies. 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
backgroundLung metastasis is the primary cause of mortality in aggressive breast cancers, particularly triple-negative breast cancer (TNBC), underscoring the urgent need for effective antimetastatic strategies.
objectiveThis study aimed to evaluate the efficacy, safety, and molecular mechanisms of Scutellaria barbata water extract (SBW) against breast cancer lung metastasis, with a focus on ferroptosis induction and epithelial-mesenchymal transition (EMT) inhibition.
methodsIn vitro and in vivo experiments to evaluate the antitumor and antimetastatic activities of SBW. Proteomic and metabolomic analyses were performed to identify key pathways and bioactive components. Ferroptosis markers and EMT-related proteins were measured by biochemical assays and Western blotting. Arachidonic acid (AA) was validated using in vitro and in vivo functional experiments.
resultsSBW dose-dependently reduced breast cancer cell viability, migration, and invasion in vitro. In vivo, SBW suppressed tumor growth and lung metastasis in 4T1 tumor-bearing mice without systemic toxicity. Proteomic analysis revealed that SBW induced ferroptosis, characterized by increased Fe
conclusionsSBW exerts potent antimetastatic effects through dual mechanisms: induction of ferroptosis via GPX4 inhibition and suppression of EMT via Twist/N-cadherin downregulation. Arachidonic acid plays a central role in mediating ferroptosis.
