Certain substrates of UGTs, such as serotonin and estradiol, play important roles in the brain. However, the expression of UGTs in the human brain has not been fully clarified. Recently, humanized UGT1 mice (hUGT1 mice) in which the original Ugt1 locus was disrupted and replaced with the human UGT1 locus have been developed. In the present study, the expression pattern of UGT1As in brains from humans and hUGT1 mice was examined. We found that [[UGT1A1]], 1A3, 1A6, and 1A10 were expressed in human brains. The expression pattern of UGT1As in hUGT1 mouse brains was similar to that in human brains. In addition, we examined the expression of [[UGT1A1]] and 1A6 in the cerebellum, olfactory bulbs, midbrain, hippocampus, and cerebral cortex of hUGT1 mice. [[UGT1A1]] in all brain regions and [[UGT1A6]] in the cerebellum and cerebral cortex of 6-month-old hUGT1 mice were expressed at a significantly higher rate than those of 2-week-old hUGT1 mice. A difference in expression levels between brain regions was also observed. Brain microsomes exhibited glucuronidation activities toward estradiol and serotonin, with mean values of 0.13 and 5.17 pmol/min/mg, respectively. In conclusion, [[UGT1A1]] and [[UGT1A6]] might play an important role in function regulation of endogenous compounds in a region- and age-dependent manner. Humanized UGT1 mice might be useful to study the importance of brain UGTs in vivo. <br /> |mesh-terms=* Adult<br /> * Aging<br /> * Animals<br /> * Brain Chemistry<br /> * Carbamazepine<br /> * Estradiol<br /> * Female<br /> * Glucuronides<br /> * Humans<br /> * Isoenzymes<br /> * Male<br /> * Mice<br /> * Mice, Inbred C57BL<br /> * Mice, Transgenic<br /> * Microsomes<br /> * Microsomes, Liver<br /> * Middle Aged<br /> * Monosaccharide Transport Proteins<br /> * Pregnenolone Carbonitrile<br /> * Serotonin<br /> <br /> |full-text-url=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4468441<br /> }}</div>
