Different mass spectrometric approaches identified 354 proteins in the urine from patients with ccRCC.
KNG1, UMOD, APOD, polyubiquitin, and CD59 were down secreted in the urine from patients with ccRCC.
APOA1, fibrinogen, and haptoglobin were up secreted in urine from patients with ccRCC.
Up-secreted and down-secreted proteins were correlated to the progression of the disease.
