News of a marker that may serve as a way to predict which cells will become cancer comes out of a recent study by researchers at Boston Children’s Hospital. Scientists were able to isolate a substance that appeared in a cell that had reverted to its stem-cell-state and then became cancerous in zebrafish that subsequently developed melanoma.
“The spark for that change was in the crestin gene, which should only be active in embryonic tissue but became inappropriately activated again, resulting in melanoma,” according to the article online at www.newvision.co.ug/. One of the authors of the study said “the beginning of cancer occurs after activation of an oncogene or loss of a tumor suppressor, and involves a change that takes a single cell back to a stem cell state.”
Now a fish is not a human being, so this information is a long way from having practical application in your doctor’s office. But the principle behind this discovery will guide further research and additional hoped-for developments.
