A giant among minnows: Giant danio can keep growing
...plained. Because genes are the key, the zebrafishs mapped genome will be invaluable in finding what is different about the danios genetic pathways that allow it to keep growing.

...the progression of cancer. First, the scientists mapped the network of genes that is activated in normal cells upon receiving the order to divide. The "divide!" signal comes from outside the cell in the form of a chemical called a growth factor, and it initiates a chain of events inside the cell.
