According to a heatmap of single‐cell GSPT1 mRNA expression in major‐lineage pan‐cancer retrieved from TISCH based on scRNA‐seq, GSPT1 is highly expressed in immune cells, particularly in Treg cells and CD8 T cells, which infiltrate the cells of PRAD, THCA, NSCLC, LIHC, HNSC, ESCA, and CRC (Figure 7A). The gene discussed is CD8A; the disease is cancer.
