BCL‐2 can inhibit apoptosis, reduce the production of oxygen‐free radicals and the formation of lipid peroxides, and increase intracellular antioxidants, such as GSH‐PX and SOD.43 In this study, the combination of lumiflavin and DDP reduced the expression of BCL‐2 in tumour tissue. Here, BCL2 is linked to neoplasm.
