Moreover, liver fatty-acid binding proteins (L-FABPs) have been widely investigated in the context of preclinical models of AKI and in specific fields (cardiac surgery, sepsis): in the setting of kidney transplantation, Yang et al. investigated urinary L-FABP and NGAL after kidney transplantation and reported the association between 0 h L-FABP values and poor long-term outcomes [111]. This evidence concerns the gene LCN2 and acute kidney injury.
