    Hepatic Levels of S-Adenosylmethionine Regulate the Adaptive Response to Fasting

    Researchers showed that in mice, hepatic S-adenosylmethionine—the principal methyl donor—acted as a metabolic sensor of nutrition to fine-tune the catabolic-fasting response.

    Alternative Splicing of CEACAM1 by Hypoxia-Inducible Factor–1α Enhances Tolerance to Hepatic Ischemia in Mice and Humans

    Investigators studied how alternative splicing of Ceacam1 affected ischemia-reperfusion injury (IRI) in mouse and human livers. They found that the short cytoplasmic isoform Ceacam1-S increased during early acute and late resolution phases of warm IRI injury in mice.

    Cullin-Associated and Neddylation-Dissociated Protein 1 (CAND1) Alleviates NAFLD by Reducing Ubiquitinated Degradation of ACAA2

    Scientists explored the role of CAND1 in the development of nonalcoholic fatty liver disease (NAFLD) and the underlying mechanisms. CAND1 was reduced in the liver of NAFLD male patients and high fat diet -fed male mice.

    ENO1 Promotes Liver Carcinogenesis through YAP1-Dependent Arachidonic Acid Metabolism

    The authors uncovered that enolase 1 (ENO1), as an RNA-binding protein, bound to the cytosine-uracil-guanine-rich elements of YAP1 messenger RNA to promote its translation.

    Thrap3 Promotes Nonalcoholic Fatty Liver Disease by Suppressing AMPK-Mediated Autophagy

    Investigators demonstrated that the hepatic expression level of thyroid hormone receptor-associated protein 3 (Thrap3) was significantly increased in nonalcoholic fatty liver disease conditions.

    Hexokinase 2 Confers Radio-Resistance in Hepatocellular Carcinoma by Promoting Autophagy-Dependent Degradation of AIMP2

    Researchers confirmed the upregulation of hexokinase 2 (HK2) in HCC tissue and demonstrated that HK2 exerteed a radio-resistant role by attenuating apoptosis and promoting proliferation in HCC cell lines.

    Loss of TP53 Cooperates with c-MET Overexpression to Drive Hepatocarcinogenesis

    Scientists discovered that the simultaneous mutations in TP53 and activation of c-MET occur in ~20% of human HCCs, and these patients show a poor prognosis.
