Recently, ANGPTL7 was identified as a biomarker upregulated selectively in the early stage of acute kidney injury, with higher transcript abundances 4 to 10 hours after ischemia reperfusion injury (according to the data in patent #EP2582840A1, http://www.google.com/patents/EP2582840A1?cl=en). This evidence concerns the gene ANGPTL7 and acute kidney injury.
