Stilbene Treatment Reduces Stemness Features in Human Lung Adenocarcinoma Model.
Article in International journal of molecular sciences, 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
Lung cancer is among the most clinically challenging tumors because of its aggressive proliferation, metastasis, and the presence of cancer stem cells (CSCs). Natural bioactive substances have been used for cancer prevention, and, in particular, resveratrol (RSV), a stilbene-based compound with wide biological properties, has been proposed for chemoprevention. Its lesser-known analogue 4,4'-dihydroxy-trans-stilbene (DHS) has demonstrated superior activity both in cell-based assays and in mouse and zebrafish in vivo models. The present study analyzed the effects of DHS and RSV on A549 lung cancer cells, with a particular focus on stemness features and CSCs, isolated by sorting of the side population (SP). The results show that both stilbenes, especially DHS, strongly inhibited cell cycle progression. A reduction in the S phase was induced by DHS, whereas an increase in this phase was obtained with RSV. In addition, 50% reductions in the clonogenicity and soft agar colony formation were observed with the DHS treatment only. Finally, both stilbenes, especially DHS, reduced stemness marker expression in A549 cells and their sorted SP fraction. Spheroid formation, higher in SP cells than in the main population (MP), was significantly reduced after pretreatment with DHS, which was found to decrease SOX2 levels more than RSV. These findings indicate that stilbenes, and particularly DHS, affect stemness features of A549 cells and the SP fraction, suggesting their potential utility as anticancer agents, either alone or combined with chemotherapeutic drugs.
