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-glomerular basement membrane (GBM) glomerulonephritis in mice using oligonucleotide microarray technology. METHODS: Kidneys were harvested at days 1, 3, 7, 11, and 16 after inducing glomerulonephritis by using anti-GBM antibody. In parallel with examining the biochemical and histologic changes, gene expression profiles were acquired against five pooled control kidneys. Gene expression levels were cross-validated by either reverse transcription-polymerase chain reaction (RT-PCR), real-time PCR, or immunohistochemistry. RESULTS: Pathologic changes in anti-GBM glomerulonephritis were confirmed in both BALB/c and C57BL/6 strains. Among the 13,680 spotted 65mer oligonucleotides, 1112 genes showing significant temporal patterns by permutation analysis of variance (ANOVA) with multiple testing correction [false discovery ratio (FDR) < 0.05] were chosen for cluster analysis. From the expression profile, acute inflammatory reactions characterized by the elevation of various cytokines, including interleukin (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 (ECM) genes. Although cytokines related to lymphocyte activation were not detected, monocyte or mesangial cell proliferation-related genes were increased. Tumor necrosis factor-alpha (TNF-alpha) and nuclear factor-kappaB (NF-kappaB) pathway were consistently activated along the entire disease progression, inducing various target genes like complement 3, IL-1b, IL-6, Traf1, and Saa1. CONCLUSION: We made a large-scale gene expression time table for mouse anti-GBM glomerulonephritis model, providing a comprehensive overview on the mechanism governing the initiation and the progression of inflammatory renal disease.
