Abstract

Serum TMAO concentrations were significantly higher in chronic kidney disease (CKD) mice compared to non-CKD mice, with females showing 29.4 ± 32.1M versus 6.9 ± 6.1M and males 18.5 ± 13.1M versus 1.0 ± 0.5M.

  • CKD mice displayed markedly decreased renal clearance of TMAO compared to non-CKD mice, with females at 5.2 ± 3.8 l/min versus 90.4 ± 78.1 l/min and males at 10.4 ± 8.1 l/min versus 260.4 ± 134.5 l/min.
  • An increase in hepatic production of TMAO was observed in CKD animals, attributed to higher activity of a specific enzyme involved in TMAO formation.
  • Increased expression of the enzyme responsible for TMAO production was noted in CKD mice, suggesting a potential mechanism for TMAO accumulation.
  • The findings indicate that both reduced kidney function and enhanced liver production may be linked to the elevated serum TMAO levels in CKD.
