The paper investigates the developmental and evolutionary origins of white pigment cells in cyprinid fishes, revealing convergent mechanisms across species.

The paper uses cell-specific isotope labeling to identify myo-inositol transfer from neurons to oligodendrocyte progenitor cells, promoting myelin repair and revealing a metabolic target for neurodegenerative disease therapy.

The paper identifies genetic regulators of fin proportion in flying fish through comparative genomics and zebrafish mutants, revealing a conserved signaling pathway involving amino acid transport and potassium channels.

The paper identifies GABA-A rho signaling as essential for maintaining quiescence of melanocyte stem cells in larval zebrafish and preventing excessive pigmentation.

The paper identifies kcnk5b as a key regulator of allometric growth in zebrafish fins by integrating calcineurin signaling.
