BSG and cancer: For nine kinds of cancers (BLCA, BRCA, KICH, LIHC, LUAD, LUSC, PRAD, THCA, and UCEC), both low infiltration levels of at least one of six types of immune cells and upregulated BSG expression were detected in cancer tissues (Supplementary Table S6), suggesting that the less infiltration of specific immune cells may be due to high expression of BSG. Notably, decreasing levels of all six types of cells and highly expressed BSG can be observed in LUSC (Supplementary Table S6), highlighting that BSG was likely to affect the six immune cell levels in LUSC patients.
