Background. Immune complexes may cause an irreversible onset of chronic renal disease. Most patients with chronic renal disease undergo a final common pathway, marked by glomerulosclerosis and interstitial fibrosis. We attempted to draw a molecular map of anti-GBM glomerulonephritis (GN) in mice using oligonucleotide microarray technology. 
Methods. Kidneys were harvested at days 1, 3, 7, 11 and 16 after inducing GN by using anti-GBM antibody. In parallel with examining the biochemical and histological changes, gene expression profile was acquired against five pooled control kidneys. Gene expression levels were cross-validated by either RT-PCR or immunohistochemistry.
Results. Pathological changes in anti-GBM GN were confirmed in both BALB/c and C57BL/6 strains. Among the 13,680 spotted 65mer oligonucleotides, 1,112 (FDR < 0.05) genes showing significant temporal patterns by permutation ANOVA with multiple-testing correction were chosen for cluster analysis. From the expression profile, acute inflammatory reactions characterized by the elevation of various cytokines, including IL-1 and IL-6, were identified within 3 days of disease onset. After 7 days, tissue remodeling response was prominent with highly induced extracellular-matrix genes. Although cytokines related to lymphocyte activation were not detected, monocyte or mesangial cell proliferation-related genes were increased. TNF-メ and NFリB pathway were consistently activated along the entire disease progression, inducing various target genes like complement 3, IL-1b, IL-6, Traf1 and Saa1. 
Conclusions. We made a large-scale gene expression timetable for mouse anti-GBM GN model, providing a comprehensive overview on the mechanism governing the initiation and the progression of inflammatory renal disease.
