By conducting a meta-analysis of differentially expressed genes (DEGs) within each cell type of the tumor microenvironment (TME), we observed that increased expression levels of specific genes, particularly BIRC5 and HIF1A, occurred in epithelial cells, CD8 T cells, T proliferative cells, mono/macro cells, basal cells, fibroblasts, and malignant cells (Figure 6B,C), while high expression levels of FLT4 occurred in malignant cells, CD8 T cells, mono/macro cells, and basal cells (Figure 6D). Here, HIF1A is linked to neoplasm.
