Lipid Remodeling in Hepatocyte Proliferation and Hepatocellular Carcinoma

Zoe Hall et al.

Summary: Our study demonstrates that specific lipid metabolic pathways are coherently altered when hepatocytes switch to proliferation, providing potential targets for therapeutic strategies and prognostic biomarkers of HCC. By integrating metabolomics, lipidomics, and transcriptomics, we have linked changes in the lipidome of proliferating hepatocytes to altered metabolic pathways including lipogenesis and generation of phosphatidylcholine. Additionally, we confirmed this altered lipid signature in human HCC and found a positive correlation of monounsaturated phosphatidylcholine with hallmarks of cell proliferation and hepatic carcinogenesis.

Liver regeneration: biological and pathological mechanisms and implications

George K. Michalopoulos et al.

Summary: The liver is a unique solid organ that uses regenerative mechanisms to maintain body homeostasis, unlike other solid organs that adjust to tissue loss but do not return to 100% of normal. This review discusses the regenerative pathways of the liver and the clinical implications of liver regeneration after injury.
