Figure 1. Expression profile of AK7 in tumor. (A) Expression of AK7 mRNA in different cancers and corresponding normal tissues. (B) The expression of AK7 mRNA in ccRCC was significantly higher than that in normal kidney tissue. (C–G) Differences in SPC25 mRNA expression depending on stage, grade, nodal metastasis status, subtype and race. (H) Expression of AK7 in normal renal tissues and ccRCC tissues. *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001.
