Renal and hepatic abnormalities are associated with upregulated GP73 expression. GP73/β-Geo staining in collecting tubules (A) and in Bowman's capsule of a kidney with hyaline thrombi (B), bars = 50 μm. RT-PCR analysis of GP73 mRNA levels from GP73+/+ mice (1), GP73tr/tr mice without renal disease (2), and GP73tr/tr mice with renal damage (3) (C). GP73/β-Geo staining in hepatocytes of a GP73tr/tr mouse with nuclear abnormalities (D), bar = 50 μm. RT-PCR of GP73 mRNA expression from livers of GP73+/+ mice treated with vehicle (control) or CCl4. (E, F) GP73 mRNA levels from control and CCl4-treated livers.
