Zebrafish

Definition

Zebrafish (Danio rerio) is a small freshwater fish that is an extensively studied vertebrate model organism. It can be bred rapidly in large numbers, is amenable to genetics, and has a clear embryo, making it attractive to study vertebrate development, physiology and disease.

    The Hippo pathway responds to environmental factors including nutrient availability, cell density and substrate stiffness to regulate organ size. This pathway is now shown to also regulate antiviral defence by modulating the TBK1-mediated control of interferon production.

    Differential redox regulation of kinase isoforms serves to provide intricate control of cellular signaling events. In a new study, a single isoform of Akt, Akt3, is shown to be preferentially modified by lipid-derived electrophiles to modulate downstream signaling events in mammalian cells and zebrafish.

    Delineating the behaviour of haematopoietic stem cells (HSCs) in vivo has thus far proven challenging. Two studies in zebrafish and mouse models now track HSCs in vivo using fate mapping with multicolour approaches to provide further insights into clonal events that regulate blood development, HSC function and differentiation during homeostasis and stress conditions.

    The Hippo pathway is a key regulator of organ size that has also been implicated in tumorigenesis. Yap, one of the effectors of Hippo signalling, is now reported to support these functions by promoting glutamine synthesis.
