MAFB and glomerulonephritis: The data showed that the average glomerulonephritis score of Mafb−/− mice (2.06) tended to be higher than that of the WT control (1.46), suggesting that the glomerulonephritis in Mafb−/− mice (34–38 weeks old) was slightly higher developed than that in WT control mice (Fig. 6e).
