Organisms can keep gene expression in check, biologist says

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.»
