Two-dimensional high-performance liquid chromatographic determination of day–night variation of d-alanine in mammals and factors controlling the circadian changes
Abstract d-Alanine (d-Ala) is one of the naturally occurring d-amino acids in mammals, and its amount is known to have characteristic circadian changes. It is a candidate for a novel physiologically active substance and/or a biomarker, and the regulation mechanisms of the intrinsic amounts of d-Ala...

| 520 | |a Abstract d-Alanine (d-Ala) is one of the naturally occurring d-amino acids in mammals, and its amount is known to have characteristic circadian changes. It is a candidate for a novel physiologically active substance and/or a biomarker, and the regulation mechanisms of the intrinsic amounts of d-Ala are expected to be clarified. In the present study, the effects of the possible factors controlling the d-Ala amounts, e.g., diet, d-amino acid oxidase (DAO) and intestinal bacteria, on the day–night changes in the intrinsic d-Ala amounts have been investigated using a highly sensitive and selective two-dimensional high-performance liquid chromatographic system combining a reversed-phase column and an enantioselective column. The circadian rhythm was not changed under fasting conditions. In the mice lacking d-amino acid oxidase activity (ddY/$ DAO^{-} $ mice), clear day–night changes were still observed, suggesting that the factors controlling the d-Ala rhythm were not their food and DAO activity. On the other hand, in the germ-free mice, quite low amounts of d-Ala were detected compared with those in the control mice, indicating that the main origin of d-Ala in the mice is intestinal bacteria. Because the d-Ala amounts in the digesta containing intestinal bacteria did not show the day–night changes, the controlling factor of the circadian changes of the d-Ala amount was suggested to be the intestinal absorption. | ||

It is a candidate for a novel physiologically active substance and/or a biomarker, and the regulation mechanisms of the intrinsic amounts of d-Ala are expected to be clarified. In the present study, the effects of the possible factors controlling the d-Ala amounts, e.g., diet, d-amino acid oxidase (DAO) and intestinal bacteria, on the day–night changes in the intrinsic d-Ala amounts have been investigated using a highly sensitive and selective two-dimensional high-performance liquid chromatographic system combining a reversed-phase column and an enantioselective column. The circadian rhythm was not changed under fasting conditions. In the mice lacking d-amino acid oxidase activity (ddY/$ DAO^{-} $ mice), clear day–night changes were still observed, suggesting that the factors controlling the d-Ala rhythm were not their food and DAO activity.

It is a candidate for a novel physiologically active substance and/or a biomarker, and the regulation mechanisms of the intrinsic amounts of d-Ala are expected to be clarified. In the present study, the effects of the possible factors controlling the d-Ala amounts, e.g., diet, d-amino acid oxidase (DAO) and intestinal bacteria, on the day–night changes in the intrinsic d-Ala amounts have been investigated using a highly sensitive and selective two-dimensional high-performance liquid chromatographic system combining a reversed-phase column and an enantioselective column. The circadian rhythm was not changed under fasting conditions. In the mice lacking d-amino acid oxidase activity (ddY/$ DAO^{-} $ mice), clear day–night changes were still observed, suggesting that the factors controlling the d-Ala rhythm were not their food and DAO activity. On the other hand, in the germ-free mice, quite low amounts of d-Ala were detected compared with those in the control mice, indicating that the main origin of d-Ala in the mice is intestinal bacteria. Because the d-Ala amounts in the digesta containing intestinal bacteria did not show the day–night changes, the controlling factor of the circadian changes of the d-Ala amount was suggested to be the intestinal absorption.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">2D-HPLC</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Chiral separation</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">-Alanine</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Circadian changes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Miyoshi, Yurika</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Konno, Ryuichi</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Koyanagi, Satoru</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mita, Masashi</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Ohdo, Shigehiro</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Hamase, Kenji</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Analytical and bioanalytical chemistry</subfield><subfield code="d">Berlin : Springer, 2002</subfield><subfield code="g">405(2013), 25 vom: 04.

Two-dimensional high-performance liquid chromatographic determination of day–night variation of d-alanine in mammals and factors controlling the circadian changes |
| abstract |
Abstract d-Alanine (d-Ala) is one of the naturally occurring d-amino acids in mammals, and its amount is known to have characteristic circadian changes. It is a candidate for a novel physiologically active substance and/or a biomarker, and the regulation mechanisms of the intrinsic amounts of d-Ala are expected to be clarified. In the present study, the effects of the possible factors controlling the d-Ala amounts, e.g., diet, d-amino acid oxidase (DAO) and intestinal bacteria, on the day–night changes in the intrinsic d-Ala amounts have been investigated using a highly sensitive and selective two-dimensional high-performance liquid chromatographic system combining a reversed-phase column and an enantioselective column. The circadian rhythm was not changed under fasting conditions. In the mice lacking d-amino acid oxidase activity (ddY/$ DAO^{-} $ mice), clear day–night changes were still observed, suggesting that the factors controlling the d-Ala rhythm were not their food and DAO activity. On the other hand, in the germ-free mice, quite low amounts of d-Ala were detected compared with those in the control mice, indicating that the main origin of d-Ala in the mice is intestinal bacteria. Because the d-Ala amounts in the digesta containing intestinal bacteria did not show the day–night changes, the controlling factor of the circadian changes of the d-Ala amount was suggested to be the intestinal absorption. © Springer-Verlag Berlin Heidelberg 2013 |
