Description:In this study, to investigate DM effects at different stages of early life, zebrafish embryos were exposed to DM just before (10-16 hpf), at the onset of (16-24 hpf), at the peak of (24-36 hpf) hypothalamic neurogenesis and across 10-120 hpf with different dosage levels (0, 1, 100, and 250 nM).
