| 中文摘要 | The objective of this study was to assess chemical-induced effects on cross-talk among the hypothalamic-pituitary-gonad (HPG), hypothalamic-pituitary-adrenal (HPA), and hypothalamic-pituitary-thyroid (HPT) axes of fish. Adult female zebrafish were exposed to 300 mu g/L prochloraz (PCZ) or 100 mg/L propylthiouracil (PTU), and the transcriptional profiles of the HPG, HPA, and HPT axes were examined. Exposure to PCZ decreased plasma testosterone (T) and 17 beta-estradiol (E2) concentrations and affected HPA and HPT axes by down-regulating corticotrophin-releasing hormone (CRH) after 12 and 48 h. By using correlation analyses, it was found that the decrease in E2 plasma concentrations caused by PCZ was correlated with the down-regulation of CRH mRNA expression. Exposure to PTU resulted in lesser concentrations of thyroxine (14) and triiodothyronine (T3), greater concentrations of follicle stimulating hormone (FSH) and luteinizing hormone (LH) peptides, and increase in steroidogenic gene expression after 12 and 48 h. Concentrations of FSH and LH were negatively correlated with concentrations of 14 and T3. These results are consistent with the hypothesis that increased steroidogenic gene expression after Pill exposure resulted from a reduction in T4 and 13 concentrations, which resulted in greater secretion of FSH and LH. |
