R linguistic analysis of RNA-Seq expression profiling data was performed to detect the association between seven immune cells (B cells, CD4+ T cells, CD8+ T cells, NK cells, macrophages, endothelial cells, and uncharacterized cells) in tumor tissues and EIF4G2, SERBP1, RPL15, and DDX3Y gene immunity. The gene discussed is RPL15; the disease is neoplasm.
