The Forkhead Box (Fox) proteins are an extensive family of transcription factors that shares homology in the winged helix DNA-binding domain and whose members play essential roles in cellular proliferation, differentiation, transformation, longevity, and metabolic homeostasis. Liver regeneration studies with transgenic mice demonstrated that FoxM1B regulates the onset of hepatocyte DNA replicat...

AIMS AND BACKGROUND The hepatocyte growth factor, its receptor c-Met, and urokinase-type plasminogen mediate various cellular responses on activation, including proliferation, survival, invasion, and metastasis. The regulatory mechanisms for the proliferation and the particular invasive phenotypes of hepatocellular carcinoma are not yet fully understood. In order to clarify the intracellular do...

We propose that a novel mechanism of hepatocyte apoptosis, involving a cooperative interaction between CD40 and Fas, is involved in the hepatocyte loss of chronic liver allograft rejection. We detected increased hepatocyte expression of Fas, Fas ligand (FasL), and CD40 associated with dropout of centrilobular (acinar zone 3) hepatocytes in chronic allograft rejection. Expression of CD40 ligand ...

BACKGROUND Quantification of hepatocyte death is useful to evaluate the progression of alcoholic liver diseases. Our aims were to quantify and correlate the circulating levels of Cytokeratin 18 (CK18) and its caspases-generated fragment to disease severity in heavy alcoholics. METHODOLOGY/PRINCIPAL FINDINGS CK18 and CK18-fragment were evaluated in the serum of 143 heavy alcoholics. Serum leve...

Hepatocyte growth factor (HGF) plays an important role in hepatocyte proliferation. HGF expression is regulated by various signaling molecules and nuclear receptors. In the present study, LiverCare(®) (LC), a novel polyherbal formulation (The Himalaya Drug Company, Bangalore, India), was evaluated for its efficacy, using co-cultures of primary rat hepatocytes-non-parenchymal cells (NPCs) and hu...

BACKGROUND/AIMS Hepatocyte replication can be induced in vivo by hepatocyte growth factor (HGF), which might be used for gene therapy or to promote liver regeneration. However, the biochemical steps critical for this process are not clear. C/EBPbeta and C/EBPalpha are liver-enriched transcription factors that induce and inhibit hepatocyte replication, respectively. Because of their role in hepa...

OBJECTIVES Despite the demonstration of oxidative stress in patients with end-stage renal disease, the oxidative status during and after a renal transplant are not completely understood. Hepatocyte growth factor is reported to act as an endogenous factor against oxidative stress. The aim of this study was to evaluate the pattern of changes in plasma oxidative status and hepatocyte growth factor...

We investigated the ability of a new type of biological material, the self-assembling peptide scaffold, to foster tissue-like function by a putative adult rat hepatocyte progenitor cell line, Lig-8. In conventional adherent petri-dish cultures, Lig-8 cells divide exponentially, express markers for definitive endoderm HNF3 beta and hepatocyte lineage, including CK8 and alpha-fetoprotein, but lac...

Patients with hepatic failure and liver-based metabolic disorders require management which is both costly and complex. Hepatocyte transplantation has been very encouraging as an alternative to organ transplantation for liver disease treatment, and studies in rodents, show that transplants involving isolated liver cells can reverse hepatic failure, and correct various metabolic deficiencies of t...

Glypicans are heparan sulfate proteoglycans that are bound to the cell surface by glycosylphosphatidylinositol. While six members of the glypican family are known in mammals, our study focused on glypican 3 (GPC3). Loss-of-function mutations of GPC3 result in the Simpson-Golabi-Behmel syndrome, an X-linked disorder characterized by pre- and postnatal liver and other organ overgrowth. GPC3 is ov...
