摘要

Organic anion transporter 1 (OAT1), primarily found in the renal proximal tubule, is essential for the excretion of various uremic toxins that contribute to the onset and progression of chronic kidney disease (CKD). OAT1 also plays a vital role in the remote sensing and signaling network, facilitating the removal of metabolites through the kidneys. The function of OAT1 is impaired under conditions such as renal ischemia/reperfusion injury, oxidative stress, and fibrosis. Several transcription factors, post-translational modifications, and endocrine hormones control the activity and expression of OAT1. This review explores the unique contribution of OAT1 to the excretion of CKD-related UTs and the mechanisms involved.
