Incorporation of Glycated-Tryptophan and -Valine into Various Cells Derived from Chicken Embryos
Avian species including chickens are known to be hyperglycemic animals. Hyperglycemia promotes the glycation which at first forms Amadori products undergoing further complex reaction to form advanced glycation end products (AGEs). Our previous study revealed that AGEs derived from glucose and amino...

description | Avian species including chickens are known to be hyperglycemic animals. Hyperglycemia promotes the glycation which at first forms Amadori products undergoing further complex reaction to form advanced glycation end products (AGEs). Our previous study revealed that AGEs derived from glucose and amino acids were predominantly incorporated into spleen, kidney and liver. However, it has not been elucidated whether Amadori products (glycated amino acids) can also be incorporated into cells or not. Therefore, in the present study, radioactive glycated-tryptophan and -valine were prepared and the incorporation of these glycated amino acids into various chicken embryonic cells was studied. Various embryonic cells prepared from muscle, liver, spleen and kidney of chicken embryos were incubated in Medium 199 supplemented with (14)C-labeled glycated-tryptophan or -valine. After incubation, embryonic cells were well-rinsed and then the radioactivity incorporated into cells was measured. It was revealed that both glycated amino acids were incorporated into embryonic cells derived from muscle, liver, spleen and kidney. In muscular cells, the incorporation of glycated-tryptophan was higher than that of glycated-valine. On the other hand, in embryonic cells derived from liver and kidney, the amount of glycated-tryptophan incorporated into cells was almost the same to that of glycated-valine. In conclusion, it was supposed that both glycated-tryptophan and -valine could be incorporated into various cells derived from muscle, liver, spleen and kidney of chicken embryos and that the incorporation might have the organ specificity. |
