1 · What the graph read from it

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.

2 · The registry

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

backgroundMacranthoside B (MB) is a saponin compound extracted from honeysuckle that has been reported to exhibit significant medicinal values, particularly anti-tumor activities. This study aimed to evaluate the anticancer efficacy of MB in treating adenocarcinoma of the esophagogastric junction (AEG) and elucidate its underlying mechanisms.

methodsThree AEG cell lines and normal gastric epithelial cells were used to assess the anticancer activity of MB in vitro. A series of experiments, including RNA sequencing (RNAseq) analysis, transmission electron microscopy (TEM), immunofluorescence, and western blot assay, were conducted to validate the molecular mechanisms by which MB may mediate these physiological changes. Finally, we used shRNA assays to silence the key gene driving these changes and examined the expression of molecules involved in the affected pathways.

resultsMB exhibited significant anti-AEG cell activity with IC50 values ranging from 9.5 to 12.7 μM. RNA-seq results indicated that MB treatment in AEG cells significantly altered mRNA levels of autophagy- and ferroptosis-related genes. Further experiments revealed that MB treatment led to the up-regulation of lipid reactive oxygen species (Lip-ROS), oxidative stress-related pathway genes, and LC3B-labeled autophagic vesicles in AEG cells. Moreover, MB mediated NCOA4-dependent ferritinophagy, disrupting iron homeostasis and causing subsequent ferroptosis. We further confirmed that the intrinsic connection between autophagy and ferroptosis was due to the inhibition of NRF2 by MB. The inhibition of NRF2 by MB triggered transcriptional repression of its downstream effector molecules HERC2 and VAMP8, thus stabilizing NCOA4.

conclusionThis study demonstrated MB to inhibit AEG cell growth by regulating iron homeostasis and inducing ferroptosis through the inhibition of NRF2, providing a basis for the development of novel drugs for AEG treatment.
