The goldfish visual pathway displays a remarkable capacity for continued development and plasticity. The intermediate filament proteins in this pathway are unexpected and atypical, suggesting these proteins provide a structure that supports growth and plasticity. Using a goldfish retina lambda gt10 library, we have isolated a full-length cDNA clone that encodes a novel type III intermediate filament protein. The mRNA for this protein is located in retinal ganglion cells, and its level dramatically increases during optic nerve regeneration. The protein is transported into the optic nerve within the slow phase of axonal transport. We have named this protein plasticin because it was isolated from a neuronal pathway well known for its plasticity.

Cloning of a type I keratin from goldfish optic nerve: differential expression of keratins during regeneration.
Druger RK, Levine EM, Glasgow E, Jones PS, Schechter N
(1992) Differentiation 52: 33-43
MeSH Terms: Amino Acid Sequence, Animals, Base Sequence, Cloning, Molecular, DNA, Goldfish, Keratins, Molecular Sequence Data, Nerve Regeneration, Optic Nerve, Protein Binding, RNA, Messenger, Sequence Homology, Amino Acid
Show Abstract · Added November 2, 2015
We report the cDNA sequence and predicted amino acid sequence of a novel type I keratin, designated as GK50, and show that keratin expression in the goldfish optic nerve is highly complex. The GK50 protein is one of at least three type I keratins expressed in goldfish optic nerve based on both antibody reactivity and blot-binding to the type II keratin ON3. After optic nerve crush in situ hybridization shows a localized increase in GK50 mRNA expression in the crush zone. This is in contrast to ON3 mRNA which shows a localized increase that is limited to the proximal and distal margins of the crush zone, suggesting a diversity of keratin expression in different cell types of the goldfish optic nerve.

Show Abstract · Added September 28, 2015
The regenerative response of minced cardiac muscle grafts in the adult newt was studied using autoradiography and electron microscopy. One-sixteenth to one-eighth of the newt ventricle was amputated, minced, and returned to the wounded ventricle. At five days after grafting, no reorganization of graft msucle pieces was apparent and there was degeneration of much of the muscle graft. Another, smaller population of 5-day myocytes had euchromatic nuclei and intact sarcolemmae. In 10- and 16-day grafts, continuity between ventricular and graft lumina was established and coalescence of graft pieces was apparent. Ultrastructurally, 10- and 16-day graft myocytes appeared to have fewer myofibrillae and increased amounts of rough endoplasmic reticulum, polyribosomes, Golig complexes, and dense bodies when compared to uninjured ventricular myocytes. The peak of proliferative activity of graft cells was observed at 16 days. Electron microscopic autoradiography revealed breadkdown of myofibrillar structure in labeled myocytes, whereas in myocytes in the later stages of mitosis only scattered myofilaments and no Z bands were present. By 30 days, grafts appeared as an integrated structure composed primarily of cardiac muscle. Myocytes of 30-day grafts were observed in various stages of myofibrillogenesis and contained numberous 10-nm filaments. Seventy-day graft mycoytes had numberous well organized myofibrillae and intercellular junctions similar to those seen in uninjured ventricular myocytes.
