Mesangioproliferative glomerulonephritis (MPGN) is a disease of high incidence in humans. Rat Thy-1 nephritis (Thy-1 N), namely, anti-thymocyte serum (ATS)-induced nephritis, is considered to be an animal model for studying MPGN. Although previous studies have demonstrated that glomerular mesangial cell (GMCs) injury might be a feature of Thy-1 N, the mechanism of the disease (i.e., GMC apoptosis) remains unclear. We have examined the pathologic changes of GMCs and the gene expression profile of renal tissues in Thy-1 N. The pathologic changes of Thy-1 N include three phages: GMC apoptosis (40 min), necrosis (2 h), and proliferation (5 days). Many TUNEL-positive cells are found 40 min after administration of ATS. Concomitantly, 341 genes are up-regulated, whereas 392 genes are down-regulated, as shown by microarrays analysis. The mRNA and protein of two of the up-regulated genes (nerve growth factor induced protein I-B, NGFI-B; growth arrest- and DNA-damage-inducible protein 45 gamma, Gadd 45 gamma) in the GMC apoptotic phase of Thy-1 N are markedly elevated, as observed by real-time polymerase chain reaction and immunohistochemistry. Our data indicate that pathologic changes of Thy-1 N are involved in the abnormal gene profile. The overexpression of the NGFI-B and Gadd 45 gamma genes may be associated with GMC apoptosis of Thy-1 N.
