Researchers have learned how living beings can keep gene expression in check -- which might partly explain the uncontrolled gene expression found in many cancers. "Using yeast as a model organism, we studied the Tup1 protein, a negative regulator of gene expression," says a biologist, adding, "This protein binds to some genes and blocks their expression, helping to ensure genes that shouldn't be turned on remain inactive."
