The capacity of the liver to regenerate is likely to be encoded as a plasticity of molecular networks within the liver. By applying a combination of comprehensive analyses of the epigenome, transcriptome, and proteome, we herein depict the molecular landscape of liver regeneration. We demonstrated that histone H3 Lys-4 was trimethylated at the promoter regions of many loci, among which only a fraction, including cell-cycle-related genes, were transcriptionally up-regulated. A cistrome analysis guided by the histone methylation patterns and the transcriptome identified FOXM1 as the key transcription factor promoting liver regeneration, which was confirmed using a hepatocarcinoma cell line. The promoter regions of cell-cycle-related genes and acquired higher levels of trimethylated histone H3 Lys-4, suggesting that epigenetic regulations of these key regulatory genes define quiescence and regeneration of the liver cells. A quantitative proteome analysis of the regenerating liver revealed that conditional protein degradation also mediated regeneration-specific protein expression. These sets of informational resources should be useful for further investigations of liver regeneration.

To investigate the promoting effect of extracellular vesicles derived from myocardial cells (CM-EVs) on the reprogramming of cardiac fibroblasts (CFs) into cardiomyocyte-like cells (iCMs) and their therapeutic effect on myocardial infarction (MI) in rats. Cell experiments: The differential adhesion method was used to obtain Sprague Dawley (SD) suckling rat CFs and cardiomyocytes (CMs), while the ultracentrifugation method was used to obtain CM-EVs. Transmission electron microscopy and nanoparticle tracking technology were used to analyze and determine the morphology and particle size of CM-EVs.

Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ) are key downstream effectors of the Hippo pathway that regulate organ size, tissue homeostasis, and cancer development. YAP/TAZ play crucial regulatory roles in organ growth, cell proliferation, cell renewal, and regeneration. Mechanistically, YAP/TAZ influence the occurrence and progression of liver regeneration (LR) through various signaling pathways, including Notch, Wnt/β-catenin, TGF-β/Smad.

Human induced pluripotent stem cell derived hepatocytes (hiPSC-heps) hold promising value for acute liver failure (ALF) treatment, while their therapeutic efficacy is usually limited by low cell bioactivity and untargeted in vivo accumulation. Here, inspired by vascularity supporting cellular architectures in the tissues and organs, a novel vascularized hiPSC-heps spheroid based on microfluidic microcapsules is presented for liver repair via orthotopic transplantation. The microcapsules are comprised of aqueous cores that facilitate hiPSC-hep aggregating into spheroids, and hybrid hydrogel shells of sodium alginate and hyaluronic acid methacryloyl (HAMA).

Liver fibrosis is a critical stage in the progression of various chronic liver diseases to cirrhosis and liver cancer. Early inhibition of liver fibrosis is crucial for the treatment of liver disease. Hepatectomy, a common treatment for liver-related diseases, promotes liver regeneration.

Background: Liuweizhiji Gegen-Sangshen oral liquid (LGS), as a Chinese medicinal preparation, is developed from a Traditional Chinese medicinal formula consisting of six Chinese medicinal herbs, including Puerariae lobatae radix, Hoveniae semen, Imperatae rhizoma, Crataegi fructus, Mori fructus and Canarli fructus, and has been extensively utilized in the prevention and treatment of alcoholic liver disease (ALD) clinically. Previous study has demonstrated that LGS dose-dependently mitigated ALD in rat models. However, whether and how the main characteristic constituents of LGS (the flavonoid and polysaccharide fractions, LGSF and LGSP) contribute to the anti-ALD effect remains unclear.
