Melatonin-induced ferroptosis in pancreatic cancer cells by stimulating endoplasmic reticulum stress and inhibiting alanine-serine-cysteine transporter 2-driven glutamine metabolism.
Article in World journal of gastroenterology, 2025. 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
backgroundPancreatic cancer, characterized by aggressive proliferation and metastasis, is a lethal malignancy. The nightly hormone melatonin serves as a rhythm-regulating hormone, and is used to treat different cancers including pancreatic cancer.
aimTo investigate how melatonin acts against human pancreatic cancer cell lines and analyze the biological processes that cause the observed effects.
methodsPanc-1 and AsPC-1 cells were treated with melatonin. Cell viability was measured using the cell counting kit-8 assay. Western blotting and immunofluorescence were used to analyze protein expression levels. Ferroptosis was measured by analyzing lipid reactive oxygen species and malondialdehyde levels; apoptosis was assessed using flow cytometry.
resultsMelatonin significantly inhibited the viability, colony formation, migration, and invasion of Panc-1 and AsPC-1 cells. Additionally, melatonin activated the endoplasmic reticulum (ER) stress pathway (protein kinase R-like ER kinase-eukaryotic initiation factor 2α-activating transcription factor 4), inhibited glutamine metabolism (alanine-serine-cysteine transporter 2-glutaminase 1-glutathione peroxidase 4, alanine-serine-cysteine transporter 2-glutathione peroxidase 4), and promoted ferroptosis in pancreatic cancer cells. Co-treatment with a high melatonin concentration and protein kinase R-like ER kinase agonist (CCT020312) enhanced melatonin-induced ferroptosis in pancreatic cancer cells. Melatonin demonstrated a variety of anticancer effects by inhibiting autophagy. This was achieved through the increased expression of sequestosome-1 and decreased expression of light chain 3. Additionally, melatonin facilitated the promotion of apoptosis.
conclusionMelatonin induces ferroptosis in pancreatic cancer cells by activating transcription factor 4-dependent ER stress and inhibiting glutamine metabolism, promotes apoptosis in pancreatic cancer cells, and inhibits autophagy, leading to synergistic anticancer effects.
