Outline of Final Research Achievements

Although kidney disease has been noticed among the diseases derived from mental stress, it is still difficult to clarify the direct relationship between nephritis disease and stress due to lacking of biomarker. In this study, addicsin, a protein expressing in both brain and kidney was proved to be useful as a stress biomarker for kidney. Moreover, a culture system under the conditions with low temperature, weak acidic pH and low oxygen concentration was successfully established to induce nephritic stress in vitro. In addition, this study demonstrated that ECM (excellular matrix) change occurred to renal glomerular basement membrane and tubules after stress induction, and the ECM change was related to inflammation appeared on kidney tissue under stress.
