Cancer cells are known for their fast and rapacious growth, but a new technique to slow them down may one day offer new treatment options.

Scientists from the US have discovered a protein called Tudor-SN linked to the “preparatory” phase of cell life – when cells prepare to divide and spread.

Using the gene-editing technology CRISPR, the researchers removed the protein, which is more abundant in cancer cells than healthy cells, and found cancer cell growth was effectively delayed.

The research team, led by Reyad Elbarbary and Keita Myoshi from the University of Rochester, in New York, made its findings in a laboratory using cells from kidney and cervical cancers.

While the technique is still far from human trials, the researchers report in the journal Science that their findings could potentially be used as a treatment option.
