| Outline of Final Research Achievements |
Several researchers have reported that Environment chemicals, such as dioxins and PCBs, cause adverse effects on human brain development. These effects may be caused through dioxin receptor (AhR)-Arnt complex, but the function of Ahr-Arnt complex on brain development, especially neural differentiation, has not been clarified sufficiently. In this study, we used human fetal brain derived neural progenitor cell line and investigated the function of Ahr-Arnt complex on neural differentiation. Moreover, the relationships between Ahr-Arnt complex and thyroid hormone receptor(TR) were also analyzed.
The knock-down of AhR/Arnt caused the changes of several neural markers. Moreover, AhR and Arnt participated the TR mediated transcription and gene expression.
These results suggested that AhR and Arnt has important roles in human neural differentiation, and also affect the function of several transcriptional factors including TR.
