1 Prostaglandin E2 inhibits its own renal transport by downregulation of organic anion transporters rOAT1 and rOAT3. Dinoprostone solute carrier family 22 member 8 Rattus norvegicus
2 The major route of PGE2 excretion is via the renal proximal tubular organic anion secretory system, where basolateral uptake that is mediated by renal organic anion transporter 1 (rOAT1) and rOAT3 is rate limiting. Dinoprostone solute carrier family 22 member 8 Rattus norvegicus
3 Therefore, it was hypothesized that PGE2 itself will abolish its excretion by rOAT1 or rOAT3. Dinoprostone solute carrier family 22 member 8 Rattus norvegicus
4 In addition, PGE2 diminishes expression of both rOAT1 and rOAT3. Dinoprostone solute carrier family 22 member 8 Rattus norvegicus
5 Both organic anion uptake and expression of rOAT1 and rOAT3 are dose-dependently downregulated by PGE2. Dinoprostone solute carrier family 22 member 8 Rattus norvegicus
