To verify that reduced PD‐L1 is responsible for weakened immune resistance of SRC‐1‐deficient CRC cells to effector CD8+ T cells, we transfected PD‐L1 expression plasmid to rescue PD‐L1 expression in SRC‐1‐deficient CRC cells (Figure S1C, Supporting Information). The gene discussed is NCOA1; the disease is colorectal carcinoma.
