Each cell line was then treated with three BmooLAAO-I concentrations - the twolowest concentrations that reduced cell viability and the IC50 value- in the presence or not of catalase at 200-400 μg/mL (Additional file 5).The three catalase concentrations tested increased cell viability to the sameextent as the previously tested concentration of 100 μg/mL, in all tumor celllines. This evidence concerns the gene CAT and neoplasm.
