Fatty acid binding protein 7 plays an important modulatory sex-dependent role on brain endocannabinoid levels and THC metabolism.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Fatty acid binding protein 7 (FABP7) is present in the brain, but its interaction with the endocannabinoid system and phytocannabinoids is still not well understood. FABP7 has been proposed as a shuttle protein for trafficking endogenous cannabinoids, as well as an intracellular carrier of THC. In a mouse model of FABP7 global deletion, we used ultra-high performance liquid chromatography- tandem mass spectrometry (UPLC-MS/MS) to measure brain levels of Δ9 tetrahydrocannabinol (THC) as well as its primary metabolite, 11-hydroxy-THC (11-OH-THC), in male and female mice after acute inhalation of THC, compared to wild-type controls. We also measured brain levels of endogenous cannabinoids anandamide (AEA) and 2-arachidonoylglycerol (2-AG) both at baseline and after acute THC inhalation. We found that in females, brain concentrations of 11-OH-THC were significantly reduced in FABP7-/- mice compared to FABP7+/+. Additionally, FABP7-/- females had significantly reduced AEA levels and significantly increased 2-AG levels in brain tissue compared to FABP7+/+. Vaporized THC administration had trending, but not significant, impacts on endocannabinoid concentrations in both males and females. Our findings suggest a sex-specific role of FABP7 in the metabolism of THC as well as the regulation of endocannabinoid levels in the brain.
