abstractText | The present study was carried out to determine how platelet-derived growth factor (PDGF)-A and -B chain mRNA expression correlate with disease activity in the renal cortex of NZB/W F1 mice, a model of systemic lupus erythematosus, and ddY mice, a model of IgA nephropathy. The PDGF-A and -B chain mRNA levels increased significantly as nephritis progressed in NZB/W F1 mice. In the renal cortex of ddY mice, however, the PDGF mRNA levels increased slightly with age. The PDGF mRNA levels in ddY mice were lower than those in NZB/W F1 mice. In the NZW control kidneys, the PDGF mRNA levels changed minimally throughout the experiments. A positive correlation was noted between PDGF mRNA levels and histopathological changes in renal tissues. At the onset of nephritis, NZB/W F1 mice were divided into two groups that received either methylprednisolone (MPSL) or saline injections for 5 months. The development of histopathological lesions and the increased PDGF mRNA levels were suppressed by MPSL treatment. These data suggest that PDGF plays a role in the progression of nephritis and that the beneficial effect of MPSL correlates with its ability to decrease the abnormally high PDGF mRNA levels seen in lupus nephritis. |
