Several studies have also demonstrated that specific protein kinases could differentially modulate Oat1 and 3 transports of organic anions.
As mentioned earlier, renal Oat1 and 3 were influenced by certain pathological status and strongly correlated with the progression of diabetic kidney diseases [16] and para-aminohippurate (PAH) is a prototypical substrate for rOat1 and 3 transporters that are mainly localized on the basolateral membrane of renal proximal tubules [8, 9, 11].
One change from the ITC white paper is that all investigational drugs should be evaluated as inhibitors of the renal uptake transporters OCT2,
OAT1, OATS, without regard to likely co-medications; the white paper recommended evaluating new drugs as inhibitors of one of these transporters if they were likely to be co-administered with a substrate of the same transporter.

OAT1 and OAT3 correlates with impaired secretion of para-aminohippurate after ischemic acute renal failure in rats.
For rat kidneys, androgen-dependent expression of
Oat1, Oat3, and Oct2 and higher expression of Oat2 in females was reported, suggesting sex-dependent renal drug handling at least in this species [12, 13].
