Abstract
A method of reducing the percentage of Epstein-Barr virus genome-carrying cells which exhibit Epstein-Barr virus early antigen induction, where the Epstein-Barr virus genone-carrying cells have been cultivated in the presence of at least one tumor-promoting chemical. The method is carried out by cultivating Epstein-Barr virus genome-carrying cells in the presence of a tumor-promoting chemical; and treating the Epstein-Barr virus genome-carrying cells with betanins. The betanins are effectively reduce the incidence of Epstein-Barr virus early antigen induction in the cultivated Epstein-Barr virus genome-carrying cells.
