Optimal cannabinoid-terpene combination ratios suppress mutagenicity of gastric reflux in normal and metaplastic esophageal cells.
Article in World journal of gastroenterology, 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
backgroundEsophageal adenocarcinoma (EAC) frequently arises from chronic exposure to acid and bile reflux, with secondary bile acids, such as deoxycholic acid (DCA), contributing to its pathogenesis through mechanisms involving reactive oxygen species (ROS), oxidative DNA damage, and resistance to apoptosis. The human endocannabinoid system (ECS) regulates diverse anti-inflammatory, antioxidant, and analgesic pathways implicated in disease modulation and may counteract the harmful effects of gastroesophageal reflux. Despite its therapeutic promise, effective pharmacological activation of the ECS remains challenging.
aimTo evaluate whether specific cannabinoid-terpene combinations targeting the ECS could attenuate the mutagenic and cytotoxic effects of bile acid-induced stress in esophageal cell models, and to assess the clinical significance of ECS-related protein receptors in the progression of EAC.
methodsHuman esophageal epithelial cells exposed to DCA, as well as a Barrett's esophagus cell line subjected to low potential of hydrogen and a bile acid cocktail, were treated with various ratios of phyto-cannabinoids and terpenes. Endpoints included DNA damage, mitochondrial membrane potential, and ROS production to identify optimal compound combinations. Expression of ECS-related receptor proteins in clinical samples was assessed by immunohistochemistry.
resultsA 1:5 ratio of cannabigerol to phytol significantly reduced DCA-induced DNA damage, preserved mitochondrial membrane potential, and decreased ROS levels. This combination also promoted apoptosis in damaged cells and reduced mutagenicity. Analysis of patient samples demonstrated that expression of the ECS-associated receptor protein CB1 correlated with EAC progression, indicating a broader clinical role for ECS modulation in cancer prevention.
conclusionModulation of the ECS using systematically selected cannabinoid-terpene ratios can attenuate bile acid-induced esophageal damage and may reduce carcinogenic progression. These findings support further
