Isoquercitrin Suppresses Esophageal Squamous Cell Carcinoma (ESCC) by Inducing Excessive Autophagy and Promoting Apoptosis via the AKT/mTOR Signaling Pathway.

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
Esophageal squamous cell carcinoma (ESCC), one of the most frequent malignant tumors of the digestive system, is marked by a poor prognosis and high mortality rate. There is a critical need for effective therapeutic strategies with minimal side effects. Isoquercitrin (IQ) is a natural compound with potent antioxidant properties in cancer and cardiovascular diseases. However, its specific effects and mechanisms in ESCC remain largely unexplored. This study aims to investigate the effects of IQ in ESCC cells and elucidate the mechanisms underlying its therapeutic effects. Specifically, its impact on cell proliferation, colony formation, migration, and invasion was assessed using cell viability assay, morphology, transwell, and colony formation assays. The effects on apoptosis were evaluated by flow cytometry, while immunofluorescence (IF) staining and Western blotting were performed to confirm the underlying mechanisms. The in vivo anti-cancer effects of IQ were then evaluated using a xenograft tumor model. Our results demonstrate that IQ inhibits ESCC cell growth and colony formation while promoting its apoptosis by enhancing caspase activation and downregulating Bcl-2 expression. Furthermore, IQ suppresses cell migration by modulating the epithelial-mesenchymal transition-related proteins. Additionally, IQ induces excessive autophagy by promoting reactive oxygen species accumulation and inhibiting the AKT/mTOR signaling pathway. Importantly, IQ effectively reduces tumor growth in vivo, highlighting its potential as a therapeutic agent for ESCC.
