To gain a thorough understanding of the significance of BMX as a therapy within the tumor microenvironment, we used the TIMER database to examine its correlation with immune cell infiltration, which includes B cells, CD8+ T cells, CD4+ T cells, neutrophils, macrophages, and dendritic cells across BRCA, COAD, LUAD, and LUSC; a positive correlation with the infiltration of all immune cells in these cancers was shown, except in BRCA which showed a negative correlation with B cells and no significant correlation with neutrophils. Here, CD8A is linked to neoplasm.
