1 · What the graph read from it

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.

2 · The registry

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

UDP-glucuronosyltransferase (UGT) is a family of enzymes that catalyze the glucuronidation of various compounds, and thereby has an important role in metabolism and detoxification of a large number of xenobiotic and endogenous compounds. UGTs are present highly in the liver and small intestine, while several investigations on quantification of UGT mRNA reported that UGTs were also expressed in the brain. However, reported expression patterns of UGT isoforms in human brain were often incongruous with each other. In the present study, therefore, we investigated UGT mRNA expressions in brains of humanized UGT1 (hUGT1) mice. We found that among the human UGT1 members, UGT1A1, 1A3, and 1A6 were expressed in the brain. We further observed that nicotine (3 mg/kg) induced the expression of UGT1A3 mRNA in the brain, but not liver. While it was not statistically significant, the nicotine treatment resulted in an increase in the chenodeoxycholic acid glucuronide-formation activity in the brain microsomes. UGT1A3 is involved in metabolism of various antidepressants and non-steroidal antiinflammatory drugs, which exhibit their pharmacological effects in the brain. Therefore, nicotine-treated hUGT1 mice might be useful to investigate the role of brain UGT1A3 in the regulation of local levels of these drugs and their response.
