Research Interests

Studies in Dr. Liu's laboratory are focused on dissecting the cellular and molecular pathways leading to chronic renal fibrosis, and exploring novel strategies for therapeutic interventions. Using a series of experimental approaches, we are addressing several fundamental issues in renal fibrosis, such as what types of cells produce a large amount of matrix proteins under pathologic conditions and how they are regulated. Current studies in our laboratory include: 1) to decipher the mechanisms controlling tubular epithelial-mesenchymal transition (EMT) and epithelial-mesenchymal cross-talks (EMC) in renal fibrogenesis; 2) to dissect several key signal pathways such as Wnt/β-catenin, hedgehog and integrin-linked kinase in the pathogenesis of renal fibrosis; 3) to elucidate the patho-mechanisms of podocyte injury and proteinuria; 4) to develop novel therapeutic strategies aimed at ameliorating renal fibrosis and kidney dysfunction.
