    TKT-PARP1 Axis Induces Radioresistance by Promoting DNA Double-Strand Break Repair in Hepatocellular Carcinoma

    Scientists investigated the functional role of transketolase (TKT) in the repair of DNA double-strand breaks (DSBs) in HCC. They unveiled that TKT was involved in DSB repair, and its depletion significantly reduced both non-homologous end joining and homologous recombination-mediated DSB repair.

    Hepatocyte GPCR Signaling Regulates IRF3 to Control Hepatic Stellate Cell Transdifferentiation

    Investigators showed that G protein-coupled receptors (GPCRs) could regulate interferon regulatory factor 3 (IRF3) phosphorylation through GPCR-Gα protein interaction.

    Investigation of the Effects of T-2 Toxin in Chicken-Derived Three-Dimensional Hepatic Cell Cultures

    To gain more accurate understanding, the effects of T-2 toxin were investigated in the present study in chicken-derived 3D primary hepatic cell cultures. 3D spheroids were treated with three concentrations of T-2 toxin for 24 hours.
