In US, researchers from the University of Rochester have identified a new way to slow down the growth of cancer cells. <br/><br/>The new method, reported in the latest issue of the journal Science, involves a certain protein called Tudor-SN and the gene-editing technology CRISPR-Cas9.<br/><br/>The findings were made in kidney and cervical cancer cells in the laboratory and are a long way from being applied to people. But the researchers said they could be the basis of a treatment option in the future. <br/>
