In the analysis of the TCGA dataset, we found that the expression of IL17A was significantly positively correlated with the expression of CD8A in invasive breast carcinoma (BRCA), liver hepatocellular carcinoma (LIHC), and ovarian serous cystadenocarcinoma (OV) in lung adenocarcinoma in TCGA (Fig. S1c). This evidence concerns the gene IL17A and ovarian serous cystadenocarcinoma.
