Zebrafish publishes special issue on cancer biology

December 12, 2015

The molecular basis for cancers affecting human germ cells is poorly understood, impeding efforts to identify more effective and targeted treatments. In the paper entitled "Identification of a Heritable Model of Testicular Germ Cell Tumor in the Zebrafish," authors Joanie Neumann, Jennifer Dhepard Dovey, Garvin Chandler, Liliana Carbajal, and James Amatruda, describe the development of a zebrafish model that carries a genetic mutation making the fish highly susceptible to the development of testicular tumors. This model system can be used to test new approaches to therapy for testicular cancer.

Jun Chen and Jinrong Peng, from Zhejian University (China), describe the use of transgenic zebrafish to understand the roles that different naturally occurring forms of the tumor suppressor gene p53 play in regulating cell cycle, metabolism, organ development, and cell aging and death. Their paper "p53 Isoform ?113p53 in Zebrafish" discusses the potential use of this particular p53 isoform for characterizing factors in the p53 pathway and screening for novel cancer therapies.

Noting the "relative ease and low costs of transgenesis"-putting human genes into zebrafish-and the unique benefits of working with zebrafish, especially related to imaging, genetics, and transplantation, Dr. Leach predicts that, "Future zebrafish cancer research exploiting these fundamental advantages will be especially likely to generate novel insights not achievable using other model systems," in his Introduction to the issue entitled, "Pisces and Cancer: The Stars Align."
