Abstract

Liver-specific knockout of in mice fed a high-fat diet leads to increased fasting levels of blood ketone bodies.

  • Clk2 suppresses fatty acid oxidation and ketone body production during diet-induced obesity.
  • In lean mice, Clk2 protein levels are low during fasting but increase during feeding, while they remain elevated in obese mice.
  • Knockout of Clk2 in the liver results in a reduced respiratory exchange ratio and increased expression of genes involved in fatty acid oxidation and ketogenesis.
  • Clk2 acts in a cell-specific manner, influencing fatty acid utilization through its effects in hepatocytes.
  • Clk2 phosphorylates a protein that disrupts its interaction with another protein, leading to decreased activation of genes associated with fatty acid metabolism.
