"A gene that may have the power to halt ovarian cancer has been discovered by UK scientists. The gene, called OPCML, was found to be inactivated in 90 per cent of ovarian cancers examined by researchers. But when the fully activated gene was inserted into ovarian cancer cells in the lab, the growth of the tumour cells was stopped."
