In addition, compared with that of MCF7/ZR75.1 cells, R‐MCF7/R‐ZR75.1 cells significantly reduced the percentage of dead tumor cells (CD45‐, SYTOX+) when the tumor cells were cocultured with PBMCs under HT‐DNA pretreatment (Figure 3E; and Figure S3E, Supporting Information). The gene discussed is PTPRC; the disease is neoplasm.
