The role of podocytic and tubular β-catenin in proteinuric kidney disease

Wnt/β-catenin signaling is a biologically highly conserved cellular signal transduction pathway that has important functions in embryogenesis, cell proliferation, cell differentiation and migration. It has been shown that the Wnt/β-catenin pathway is essential for regeneration and repair of tubular damage in acute kidney injury. In contrast, constant activation of Wnt/β-catenin signaling in chronic kidney disease leads to progression of the disease, so that in this case β-catenin inhibition may have protective effects. In this project, we aim to investigate how we can promote the beneficial function of β-catenin in both glomerulus and tubule, focusing particularly on proteinuric kidney disease.

Gpr126 (Adgrg6) in kidney development and disease

Prof. Dr. rer. nat. Dipl. Ing. Felix B. Engel
Friedrich-Alexander-Universität Erlangen-Nürnberg

Chronic kidney disease represents the fastest growing pathology worldwide. Elucidating new regulators of kidney development and disease will promote the development of strategies for kidney repair. Based on our preliminary data, we conclude that
1) Gpr126 is expressed in the collecting duct,
2) in contrast to the heart, where only the NTF is required for proper development, kidney development depends on CTF and NTF,
3) Gpr126 expression is upregulated during renal disease, and
4) in renal disease Gpr126 is ectopically expressed in renal cells other than collecting duct cells.
Thus we hypothesize that Gpr126
1) contributes to the differentiation of the nephron establishing segment identity,
2) might be useful as diagnostic marker in kidney disease, and/or
3) is a promising new therapeutic target for renal diseases. Therefore, we propose to characterize the expression pattern of Gpr126 in kidney development and disease and to elucidate the role of Gpr126 function during kidney development.
