One such condition is the inherited metabolic disorder alkaptonuria (AKU), caused by mutations in the gene encoding the homogentisate 1,2-dioxygenase (HGD) enzyme. HGD is expressed in liver and kidney. In AKU, lack of functional HGD results in incomplete breakdown of the amino acid tyrosine and accumulation of homogentisic acid (HGA), the indicative metabolite in AKU. Here, we aimed to delineate the role of the kidney in production and metabolism of HGA. We generated for the first time a mouse with specific deletion of Hgd in the kidney but not in the liver, using Cre recombinase driven by Six2 (Six2GCiP), a transcription factor expressed early in kidney development. With intact liver HGD in this mouse, plasma HGA remained equivalent to wild-type concentrations. Minimal circulating HGA combined with no apparent renal HGD activity enabled us to unmask the portion of HGA produced locally within the kidney. Urine HGA (mean ± SEM) was > 100-fold lower in kidney-specific Hgd knockout mice (717 ± 129 μmol/L) compared to AKU mice (118 364 ± 8494 μmol/L) with complete liver and kidney knockout, but higher than wild-type controls (2.3 ± 0.1 μmol/L). Profiling of tyrosine pathway metabolic enzymes showed human and mouse kidney lack detectable tyrosine aminotransferase, a key enzyme involved in tyrosine-HGA metabolism.
