In the HPA database, protein expressions of the seven genes (ADAMTS8, CCR2, CYSLTR2, FAM129C, FCER1A, GAPT, PKHD1L1, and ZNF831) were markedly low in tumor tissues with less intense antibody staining and fewer stained cells in LUAD (Figure 7). The gene discussed is CYSLTR2; the disease is neoplasm.
