The correlation coefficient of the ASCL2 with immune-associated cells in STAD is shown in Fig. 5A. We can easily infer that the ASCL2 reveals a positive correlation with the levels of M2 macrophages and T follicular helper cells and shows a negative correlation with the levels of neutrophils, dendritic cells, monocytes, CD8 T cells, and M1 macrophages. The gene discussed is ASCL2; the disease is gastric adenocarcinoma.
