Metapath2vec and attention-driven heterogeneous graph learning for prioritizing TCM-derived small molecules in gastric cancer.
Article in Chinese medicine, 2026. 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
Traditional Chinese Medicine (TCM) represents a multi-component therapeutic system with substantial chemical complexity. This complexity makes it difficult to directly elucidate anti-gastric cancer mechanisms from macroscopic herbal formulae. To support the systematic prioritization of potential small-molecule candidates, this study focuses on screening bioactive small-molecule constituents from TCM. We constructed a heterogeneous network integrating Chinese herbal pieces (CHPs), Chinese patent medicines (CPMs), genes, diseases, and small molecules, and incorporated metapath2vec representations and attention mechanisms into a graph neural network framework, the model is designed to learn relational patterns among heterogeneous nodes. Network pharmacology and in vitro validation in AGS and MKN-45 gastric cancer cell lines show that Icaritin and Arundine inhibit cell proliferation and induce apoptosis. This study presents an AI-assisted pipeline for candidate prioritization, providing methodological support for the systematic prioritization and preliminary validation of bioactive TCM molecules in gastric cancer.
