CTSG and neoplasm: The differential expression analysis results suggested that the expression level of LRP2, DNASE2B, SLC11A1, ATP6V0D2, LAMP3, IFI30, TYR, MYO7A, NEU4, and AZU1 was overexpressed in tumor tissues, whereas the expression level of ADRB2, CTSG, and CTSF was expressed higher in normal tissues (Figure 1A).
