Differences in xanthotoxin metabolites in seven mammalian liver microsomes.
Article in Experimental and therapeutic medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Xanthotoxin, abundantly occurring in fruits, vegetables, grapefruit juice and oils, is widely used in medicine for the treatment of psoriasis and vitiligo. Xanthotoxin possesses the ability to inhibit mechanism-based cytochrome P450 (CYP450)-mediated activities in rats and mice. Furthermore, it time-dependently obstructs a number of CYP450-mediated functions in humans. CYP450 enzymes are most abundant in the liver and induce metabolic activation of numerous xenobiotic compounds. The present study aimed to identify the similarities and differences in xanthotoxin metabolism in liver microsomes of 7 mammalian species, including human liver microsomes (HLM), Rhesus monkey liver microsomes (RMLM), Cynomolgus monkey liver microsomes (CMLM), Sprague Dawley rat liver microsomes (RLM), mouse liver microsomes (MLM), Dunkin Hartley guinea pig liver microsomes (PLM) and Beagle dog liver microsomes (DLM). Ultra-high performance liquid chromatography/quadrupole time-of-flight mass spectrometric analysis was used to determine the metabolites. A total of 3 metabolites were detected in RMLM, CMLM and RLM. Furthermore, two metabolites were observed in MLM, HLM, PLM and DLM. By analyzing the type and quantity of metabolites, the metabolism of xanthotoxin in MLM was indicated to be most similar to that in HLM. The metabolic transformations of xanthotoxin in the liver microsomes of the 7 species were analyzed in further detail. On the whole, the results of the present study provide a deeper understanding of the metabolic patterns of xanthotoxin in liver microsomes of different species, which may prove to be advantageous regarding the metabolic mechanisms of action of xanthotoxin. Further insight into drug metabolism with respect to different species will also aid in the selection of appropriate animal models for further research.
