Zebrafish help decode link between calcium deficiency and colon cancer


A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer.

By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells.
