Project description:Effects of egg enrichment with glucocorticoid hormone, antagonist and receptor messenger in the modulation of gene expression in zebrafish (Danio rerio) embryos
Project description:Dieldrin is a legacy pesticide that has multiple modes of action (MOA) that include being an estrogen receptor agonist, GABA receptor antagonist, and a chemical that disrupts mitochondrial function. There is also evidence that dieldrin exposure is significantly associated with an increased risk for neurodegeneration in humans. The objective of this thesis was to clarify the effects of dieldrin in the hypothalamus, the major neuroendocrine region of the brain, in the zebrafish (Danio rerio). Zebrafish were fed pellets containing 0.03, 0.15, or 1.8 µg/g dieldrin for 21 days and a global gene expression analysis was performed to characterize cellular processes and pathways affected by dieldrin.
Project description:The embryo-larval and adult parts of the zebrafish major alpha/beta-globin gene locus are functionally and structurally independent
