Furthermore, our analysis of paired tumor and adjacent normal samples from the TCGA dataset revealed significantly elevated SLAMF7 expression in tumor tissues of head and neck squamous cell carcinoma (HNSC), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), and lung adenocarcinoma (LUAD) compared to their adjacent normal tissues (Figure S2D). This evidence concerns the gene SLAMF7 and lung adenocarcinoma.
