| Outline of Final Research Achievements |
We studied integration of proteomics and metabolomics to identify the intracellular metabolic pathway involved in the progression to glomerulosclerosis, which contributes to the discovery of the novel anti-glomerulosclerosis agents. The study employed two rodent glomerulosclerosis models: adriamycin nephrosis and NEP25 immunotoxin nephritis. Mass spectrometry for proteomics using isolated glomeruli revealed transgelin to be highly expressed in the glomerulus both at an initial- and late stage in both glomerulosclerosis models. Mass spectrometry for metabolomics revealed the different distribution of the metabolites between the control and NEP25 immunotoxin nephritis. These data suggest that the identification of these altered metabolites may contribute to the regulatory pathway of transgelin that possibly underlies the pathomechanism of the glomerulosclerosis.
