Indoxyl sulfate (IS), a protein-bound uremic toxin that accumulates in patients with declining renal function, is known to be associated with epithelial-mesenchymal transition (EMT) in proximal renal tubular cells.

Cells were treated with IS or combined with β-catenin inhibitor ICG-001, and high glucose PD fluid (PDF) served as a positive control. Morphology, proliferation and adhesion were assessed, while the expression of β-catenin and α-smooth muscle actin (α-SMA) as mesenchymal markers, along with E-cadherin as a mesothelial marker, were analyzed at both RNA and protein levels using real-time polymerase chain reaction (PCR) and western blot, respectively.</p><p><strong>Results: </strong>The number of viable and adherent cells was significantly increased in the IS and PDF groups compared to the control (p < 0.05).
