    An Autocrine Signaling Circuit in Hepatic Stellate Cells Underlies Advanced Fibrosis in Nonalcoholic Steatohepatitis

    To identify antifibrotic drug targets, researchers integrated progressive transcriptomic and morphological responses that accompanied hepatic stellate cell activation in advanced disease using single-nucleus RNA sequencing.

    Lactylome Analysis Suggests Lactylation-Dependent Mechanisms of Metabolic Adaptation in Hepatocellular Carcinoma

    Investigators showed a global lactylome profiling on a prospectively collected hepatitis B virus-related HCC cohort. They revealed that lysine lactylation played an important role in regulating cellular metabolism and may contribute to HCC progression.

    Circadian Regulator BMAL1::CLOCK Promotes Cell Proliferation in Hepatocellular Carcinoma by Controlling Apoptosis and Cell Cycle

    The authors suggested that the circadian clock regulators BMAL1 and CLOCK promoted HCC cell proliferation by controlling Wee1 and p21 levels, thereby preventing apoptosis and cell cycle arrest.

    KLF14 Regulates the Growth of Hepatocellular Carcinoma Cells via Its Modulation of Iron Homeostasis through the Repression of Iron-Responsive Element-Binding Protein 2

    Investigators generated krüpple-Like factor 14 (KLF14) overexpression and silencing liver cancer cells, and nude mouse xenograft models for the in vitro and in vivo study exploring the function of KLF14 in HCC.

    Single-Cell RNA Sequencing Identifies a Population of Human Liver-Type ILC1s

    Scientists identifed a population of “liver-type” innate lymphoid cells 1 with transcriptional, phenotypic, and functional features distinct from those of conventional and liver-resident natural killer cells.

    O-GlcNAcylation of SPOP Promotes Carcinogenesis in Hepatocellular Carcinoma

    Investigators showed that, in HCC, speckle-type POZ protein (SPOP) was highly O-GlcNAcylated by O-GlcNAc transferase at Ser96.

    Abstract

    Deubiquitinating Enzyme Josephin-2 Stabilizes PHGDH to Promote a Cancer Stem Cell Phenotype in Hepatocellular Carcinoma

    Scientists designed a study to reveal the effect and underlying mechanism of Josephin-2, a relatively newly defined deubiquitinating enzyme, in HCC progression.

    Abstract

    Cadmium Modulates Steatosis, Fibrosis, and Oncogenic Signaling in Liver Cancer Cells by Activating Notch and AKT/mTOR Pathways

    Researchers investigated the effect of a physiologically relevant, low concentration of cadmium on the regulation of liver cancer cell proliferation, steatosis, and fibrogenic/oncogenic signaling.

    Age-Related Liver Endothelial Zonation Triggers Steatohepatitis by Inactivating Pericentral Endothelium-Derived C-kit

    Scientists showed that liver sinusoidal endothelial cell senescence-accelerated liver sinusoid capillarization and promoted steatosis by reprogramming liver endothelial zonation and inactivating pericentral endothelium-derived C-kit.
