Mechanism of LPS-activated gingival fibroblasts promote the migration of gastric cancer cells via CXCL12/CXCR4-Snail2-EMT axis.
Article in In vitro cellular & developmental biology. Animal, 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
The objective of this article is to explore the influence and process by which periodontitis affects the metastasis of gastric cancer cells. Human gingival fibroblasts (HGFs) underwent stimulation with lipopolysaccharide (LPS), and ELISA was used to detect inflammatory factor expression. Using cell co-culture technology, the effect of HGFs on the migration of gastric cancer cells was observed. CCK8, qPCR, Western blot, RNAi, Cell scratch and transwell were used to analyze the relationship between CXCL12/CXCR4, Snail2 and EMT, and their effects on cancer cell migration. The results showed that CXCL12 levels rise in periodontitis and gastric cancer. HGFs can promote the migration of gastric cancer cells. CXCL12 also boosts Snail2 expression in gastric cancer cells. AMD3100 and si-CXCR4 can significantly inhibit the expression of Snail2. Moreover, CXCL12 can promote EMT, while si-Snail2 and si-CXCR4 significantly reduced the upregulation trend of N-cadherin and Vimentin expression, and reverses the downregulation trend of E-cadherin expression. CXCL12 can promote the migration of gastric cancer cells, while the migration rates of gastric cancer cells are notably reduced after AMD3100, si-CXCR4 or si-Snail2 intervention. In summary, the CXCL12/CXCR4-Salil2-EMT signaling pathway is involved in the migration of gastric cancer cells promoted by periodontitis. This will uncover new insights into the mechanisms that might play a role in the development of gastric cancer and strategies for targeted therapy.
