The expression levels of apoptotic genes (Caspase 3, Bax, and Fas) and anti-apoptotic gene (Bcl-2) in the kidney tissue of each group were detected using real-time qPCR, and the results showed that the expression levels of those apoptotic genes in the AKI model group were much higher than those in the normal group. This evidence concerns the gene CASP3 and acute kidney injury.
