| Research Abstract |
Regeneration-associated genes (RAGs) were cloned from axotomized zebrafish retina. HSP70 (a stress protein) and purpurin (a retinol-binding protein) were rapidly induced in the fish retina after optic nerve injury. HSP70 was involved in cell survival of injured retinal ganglion cells (RGCs), whereas purpurin was involved in neurite sprouting from injured RGCs. These RAGs could easily induce regrowth of axotomized optic nerve in adult rat.
