Research background Prof. Dr. Jochen Fries

In the experimental thesis (Prof. Thoenes, Pathology, Univ. Clinic, Mainz, Germany) a backleak of tubular fluid caused by tubular necrosis in the S3 segment due to a continued ischemic environment was shown by light and electron microscopy as cause of prolonged acute renal failure. A morphometric analysis of glomerular epithelial damage in proteinuric renal disease (1980-1984) demonstrated that only a small amount of all glomerular epithelial podocytes is altered in proteinuric/hematuric diseases in adults and children independent of the degree of proteinuria. Studying mechanism of proteinuria in a DFG-funded project at the Brigham and Women’s Hospital, Boston, MA, USA (Pathology, Laboratory of Prof. Dr. H. Rennke; 1984-1987) an immune complex mediated versus hypertensive model of glomerular disease was established showing the importance of the location immune complex deposition versus hemodynamic forces as determinants for progressive glomerular damage. A molecular biology project at the Harvard School of Public Health (Public Health; Prof D. Wirth, 1987-1989) in molecular mycobacteriology provided the basis for future studies at the molecular level, establishing DNA probes for diagnostic analyses for M. avium and the genus Mycobacteria. Studies in molecular vascular research (PDGF-transgenic mouse; cloning and characterisation of E-selectin and vascular cell adhesion molecule-1; Pathology, Brigham and Women’s Hospital; Prof. T. Collins; 1987-1997) as well as working as a consultant for experimental animal research (Prof. J. Halperin; Lab. of Transport Physiology; Harvard Medical School; 1994-1997) became important steps for future studies. In Köln (Pathology; since 1997) a microdissection method for analysing glomerular disease in formalin-fixed, paraffinized biopsies was established funded by the DFG.

The availability of virus-targeted gene delivery as well as the stem cell technology have been part of the research repertoire for renal and cardiac disease through scientific ollaboration. The participation in the program of the DSO (Deutsche Stiftung Organtransplantation) in pre-transplant organ evaluation as well as the evaluation of non-allocated livers and kidneys have led to an intense interest in the problems of organ transplantation.

Over the last 5 years, research efforts have focussed on the role of endothelin in progressive renal disease and renal tumors. The signalling pathway via the ET-A-receptor and a cytoplasmic transcription complex consisting NF-kBp65, MAPKp38 and PKCα migrating into the nucleus has been analysed in normal and tumorous proximal tubule cells/human tumors.
