Moreover, we found a positive correlation between S100A7 expression and the estimated infiltration value of cancer-associated fibroblasts in the TCGA cancers of BRCA-LumA, BRCA-LumB, and LUAD; however, S100A7 expression was negatively correlated in CESC, HNSC, HNSC-HPV-, and STAD (Figure 5C,D and Figure S11b). The gene discussed is S100A7; the disease is cancer.
