Myc-induced T cell leukemia in transgenic zebrafish.

TLDR
Visualization of leukemic cells expressing a chimeric transgene encoding Myc fused to green fluorescent protein (GFP) revealed that leukemias arose in the thymus, spread locally into gill arches and retro-orbital soft tissue, and then disseminated into skeletal muscle and abdominal organs.
Abstract
The zebrafish is an attractive model organism for studying cancer development because of its genetic accessibility. Here we describe the induction of clonally derived T cell acute lymphoblastic leukemia in transgenic zebrafish expressing mouse c-myc under control of the zebrafish Rag2 promoter. Visualization of leukemic cells expressing a chimeric transgene encoding Myc fused to green fluorescent protein (GFP) revealed that leukemias arose in the thymus, spread locally into gill arches and retro-orbital soft tissue, and then disseminated into skeletal muscle and abdominal organs. Leukemic cells homed back to the thymus in irradiated fish transplanted with GFP-labeled leukemic lymphoblasts. This transgenic model provides a platform for drug screens and for genetic screens aimed at identifying mutations that suppress or enhance c-myc- induced carcinogenesis.

Transplantation and in vivo imaging of multilineage engraftment in zebrafish bloodless mutants

TL;DR: The zebrafish is firmly established as a genetic model for the study of vertebrate blood development and its blood-forming system is characterized to provide a cellular context in which to study the genetics of hematopoiesis.

The identification of genes with unique and essential functions in the development of the zebrafish, Danio rerio

TL;DR: It is estimated that the 372 genes defined by the mutants probably represent more than half of all genes that could have been discovered using the criteria of the screen, and the limits and the potentials of a genetic saturation screen in the zebrafish.

Sustained Loss of a Neoplastic Phenotype by Brief Inactivation of MYC

TL;DR: It is demonstrated that brief inactivation of MYC results in the sustained regression of tumors and the differentiation of osteogenic sarcoma cells into mature osteocytes, raising the possibility that transient in activation ofMYC may be an effective therapy for certain cancers.
