Characterization of Phosphatidylcholine Metabolism in Mouse Hepatocytes after Hepatectomy and in Primary Human Hepatocytes
DownloadSpring 2012
Phosphatidylcholine (PC) is the major component of mammalian membranes and the induction of PC biosynthesis has been shown to be an essential step in cell proliferation in various cell lines. In the liver, PC biosynthesis is regulated by two pathways: the CDP-choline and the...

Insights into the Role of Choline Kinase in Endochondral Bone Formation and Human Osteoblasts Function
DownloadSpring 2014
Choline kinase (CK) phosphorylates choline to phosphocholine (PCho) and is the first enzyme in the CDP-choline pathway that generates phosphatidylcholine (PC). CK has three isoforms (CKα1, CKα2 and CKβ) that are encoded by two genes, Chkα and Chkb. Inactivation of Chkα results in embryonic...

Insights into the Role of Phosphatidylethanolamine N-methyltransferase and the PC:PE Ratio in Liver Function
DownloadSpring 2019
PEMT is quantitatively important in the liver and is responsible for approximately 30% of hepatic PC synthesis, with the remaining 70% synthesized by the CDP-choline pathway. HFD-fed Pemt-/- mice and LPcyt1a-/- mice both develop NAFLD associated with reduced VLDL secretion and a reduced hepatic...
