Differences in AGT excretion between CKD etiologies can probably be explained by differences in filtration and/or tubular reabsorption (Kobori et al., 2008; Urushihara et al., 2010; Nishiyama et al., 2011; Park et al., 2015b; Salih et al., 2017; Tang et al., 2018; Kim et al., 2019; Ohashi et al., 2020). Here, AGT is linked to chronic kidney disease.
