[67] compared serial urinary proteomes of patients with (serum creatinine increase > 50%) or without AKI before, during, and after cardiopulmonary bypass surgery and found that CXCL10 was upregulated postoperatively in patients with AKI, which corresponds temporally to the later phase(s) of tubular injury unique to patients with AKI.
