PGK1 and neoplasm: Because the above data sources were all from bulk RNA-seq or whole tissue microarray, in order to reduce the influence of non-tumor cells in the tumor microenvironment, we analyzed single-cell sequencing data from GSE131907 in Figure 1G,H to verify the expression difference of PGK1 between tumor cells and normal epithelial cells from the single-cell level (Figure S2).
