The urinary levels of the soluble ADAM17 substrates (AREG [A], TNFR1 [B], HB-EGF [C], TGFα [D], Axl [F], ICAM1 [G], and KIM1 [H]) and of the ADAM10 substrate cMET (E) were measured by ELISA in control, AKI, and CKD patients (n = 10; 50% of CKD patients were diabetics; patient demographics and details in Supplemental Table 1). *P < 0.05; **P < 0.01; ***P < 0.001 as determined by an unpaired 2-tailed Student’s t test. AREG, amphiregulin; TNFR, tumor necrosis factor receptor; AKI, acute kidney injury; CKD, chronic kidney disease; ADAM17, a disintegrin and metalloprotease 17; HB-EGF, heparin binding epidermal growth factor-like growth factor; ICAM1, intercellular adhesion molecule 1; KIM1, kidney injury molecule 1; cMET, met.
