Clinical analyses of Oncomine “Gaber lung” dataset showed that USP4 mRNA levels were elevated in lung cancer specimens compared to normal tissues (Figure 1J), and analyses of Oncomine “Bild lung” dataset showed that stage II-IV lung cancer specimens had elevated USP4 mRNA levels compared to stage I lung cancer specimens (Figure 1K). The gene discussed is USP4; the disease is lung carcinoma.
