The use of cell cycle arrest biomarkers in the early detection of acute kidney injury. Is this the new renal troponin?

Acute kidney injury (AKI) has a high prevalence in critical care patients. Early detection might prevent patients from developing chronic kidney disease and requirement for renal replacement therapy. If we compare AKI with acute coronary syndrome, in which an increase in cardiac troponin may trigger...
