Larval zebrafish proteome regulation in response to an environmental challenge
2019
Adaptation to the environment during development influences the life-long survival of an animal. While brain-wide proteomic changes are expected to underlie such experience-driven physiological and behavioral flexibility, a comprehensive overview of the nature and extent of the proteomic regulation following an environmental challenge during development is currently lacking. In this study, the brain proteome of larval zebrafish is identified and it is determined how it is altered by an exposure to a natural and physical environmental challenge, namely prolonged exposure to strong water currents. A comprehensive larval zebrafish brain proteome is presented here. Furthermore, 57 proteins that…
The neuropeptide Pth2 modulates social behavior and anxiety in zebrafish
2021
SummaryAnimal behavior is strongly context-dependent and behavioral performance is often modulated by internal state. In particular, different social contexts can alter anxiety levels and modulate social behavior. The vertebrate-specific neuropeptide parathyroid hormone 2 (pth2) is directly regulated by the presence or absence of conspecifics in zebrafish. As its cognate receptor, the parathyroid hormone 2 receptor (pth2r), is widely expressed across the brain, we tested fish lacking the functional Pth2 peptide in several anxiety-related and social paradigms. Rodents lacking PTH2 display increased anxiety-related behavior. Here we show that the propensity to react to sudden stimuli with an …
