Human Endogenous Metabolite
D-kynurenine (10, 40, 60, and 100 µM) positively regulates the metastasis of 95D cells, a lung cancer cell line, which is reduced upon siRNAAhr treatment. Significant enhancement VIM expression was detected in the presence of D-kynurenine (10 and 40 µM). 10 µM D-kynurenine markedly attenuates E-cadherin level. 10 µM D-kynurenine-mediated changes of VIM and E-cadherin are substantially attenuated on siRNAAhr treatment as well. The evidences-10/40 µM D-kynurenine-induced up-regulation of CYP1A1, 10 µM D-kynurenine-induced increase of nuclear transfer of Ahr, and 10/40/60/100 µM D-kynurenine-induced enhancement of DER-luciferase activity-indicated that D-kynurenine Is capable of activating Ahr in fact.
