BACKGROUND: The obesity epidemic has significantly increased the incidence and severity of hepatic steatosis in liver surgery patients and liver donors, potentially impacting postoperative liver regeneration and function. Development of a non-invasive means to quantify hepatic steatosis would facilitate selection of candidates for liver resection and transplant donation. METHODS: An IRB-approved protocol prospectively enrolled 28 patients with liver tumors requiring hepatic resection...

Alcoholic hepatitis manifests as a clinical syndrome characterized by recent jaundice and liver function deterioration in an actively drinking patient. The principal cause of alcoholic hepatitis is alcoholic steatohepatitis defined histologically by the coexistence of steatosis, hepatocyte ballooning and satellitosis. While non-severe alcoholic hepatitis usually responds to alcohol abstinence, severe alcoholic hepatitis, identified by Maddrey scoring ≥ 32, has a bad prognosis and is traditionally treated by a 28-day course of prednisone therapy...

The long-term prognosis following resection of hepatocellular carcinoma (HCC) remains unsatisfactory as a result of a high incidence of recurrence. Prevention of recurrence is the most important strategy to improve the long-term survival results. The role of hepatectomy itself, as an accelerator of carcinogenesis, has not been adequately evaluated in HCC patients. Studies in animal models have revealed a link between liver regeneration under chronic inflammation and hepatic tumorigenesis. Inhibiting different signal transduction pathways during liver regeneration without compromising the ability of the liver to regenerate appears to be a rational strategy and may decrease HCC development and recurrence...

Severe alcoholic hepatitis is implicated as a costly, worldwide public health issue with high morbidity and mortality. The one-month survival for severe alcoholic hepatitis is low with mortality rates high as 30%-50%. Abstinence from alcohol is the recommended first-line treatment. Although corticosteroids remain as the current evidence based option for selected patients with discriminant function > 32, improvement of short-term survival rate may be the only benefit. Identification of individuals with risk factors for the development of severe alcoholic hepatitis may provide insight to the diverse clinical spectrum and prognosis of the disease...

Nitric oxide (NO), generated from L-arginine by three different isoforms of nitric oxide synthase (NOS), is a pleiotropic factor to regulate physiological functions in almost every organ and tissue. Each knockout mouse of iNOS or eNOS has been used to suggest that NO has a crucial role in liver regeneration after partial hepatectomy (PH), for NO may inhibit caspase 3 activity and is required for EGFR signaling. In previous reports, defective mitochondrial β-oxidation was observed in eNOS KO mice, and hepatic steatosis was often correlated to deficient liver regeneration, so we focused on metabolic perspective and hypothesized that NO depletion in PH mice would affect hepatocytic lipolysis and impair hepatocytes proliferation...

The acute-phase response (APR) is an inflammatory process triggered mainly by IL-6 in response to neoplasm, tissue injury, infection or inflammation. Signaling of IL-6 is transduced by activating STAT3 which rapidly results in production of acute-phase proteins (APPs) such as fibrinogen β (FGB) and haptoglobin (HP). Augmenter of liver regeneration (ALR), a hepatotrophic factor supporting liver regeneration, was reported to be upregulated after liver damage. In this study we analyzed the role of ALR for IL-6 signaling and APR...

Liver regeneration is a fascinating and complex process with many medical implications. An important component of this regenerative process is the hepatic progenitor cell (HPC). These appealing cells are able to participate in the renewal of hepatocytes and cholangiocytes when the normal homeostatic regeneration is exhausted. Moreover, the HPC niche is of vital importance toward the activation, differentiation, and proliferation of the HPC. This niche provides a rich microenvironment for the regulation of the HPC, thanks to the intercellular secretion of molecules...

Crosstalk between mesenchymal and epithelial cells influences organogenesis in multiple tissues, such as lung, pancreas, liver, and the nervous system. Lung mesenchyme comprises multiple cell types, however, and precise identification of the mesenchymal cell type(s) that drives early events in lung development remains unknown. Endothelial cells have been shown to be required for some aspects of lung epithelial patterning, lung stem cell differentiation, and regeneration after injury. Furthermore, endothelial cells are involved in early liver and pancreas development...

BACKGROUND: Liver resection or partial hepatectomy (PH) is still the most commonly used therapeutic option for hepatocellular carcinoma (HCC) at present. However, the impaired regenerative ability induced by the accompanied liver cirrhosis is an important risk factor of posthepatectomy liver failure, and posthepatectomy liver failure is a feared complication that accounts for up to 75% of mortality after extensive liver resection. MicroRNA(miR)-203 is a tumor suppressor of HCC and may act as a positive intermediary in A20-enhanced interleukin (IL-6)/signal transducer and activator of transcription 3 (STAT3) pro-proliferative signals, which may promote liver regeneration after PH...

Purpose To demonstrate the feasibility of imaging-guided catheter-directed delivery of endothelial cell therapy in a porcine model of cirrhosis for liver regeneration. Materials and Methods After approval from the institutional animal care and use committee, autologous liver endothelial cells were grown from core hepatic specimens from swine. Cirrhosis was induced in swine by means of transcatheter infusion of ethanol and iodized oil into the hepatic artery. Three weeks after induction of cirrhosis, the swine were randomly assigned to receive autologous cell therapy (endothelial cells, n = 4) or control treatment (phosphate-buffered saline, n = 4) by means of imaging-guided transhepatic intraportal catheterization...

Hepatitis C virus represents one of the rising causes of hepatocellular carcinoma (HCC). Although the early diagnosis of HCC is vital for successful curative treatment, the majority of lesions are diagnosed in an irredeemable phase. This work deals with a comparative ultrastructural study of experimentally gradually induced HCC, surgically resected HCC, and potential premalignant lesions from HCV-infected patients, with the prospect to detect cellular criteria denoting premalignant transformation. Among the main detected pathological changes which are postulated to precede frank HCC: failure of normal hepatocyte regeneration with star shape clonal fragmentation, frequent elucidation of hepatic progenitor cells and Hering canals, hepatocytes of different electron density loaded with small sized rounded monotonous mitochondria, increase junctional complexes bordering bile canaliculi and in between hepatocyte membranes, abundant cellular proteinaceous material with hypertrophied or vesiculated rough endoplasmic reticulum (RER), sequestrated nucleus with proteinaceous granular material or hypertrophied RER, formation of lipolysosomes, large autophagosomes, and micro-vesicular fat deposition...

Interventional radiology plays a major role in the modern management of liver cancers, in primary hepatic malignancies or metastases and in palliative or curative situations. Radiological treatments are divided in two categories based on their approach: endovascular treatment and direct transcapsular access. Endovascular treatments include mainly three applications: transarterial chemoembolization (TACE), transarterial radioembolization (TARE) and portal vein embolization (PVE). TACE and TARE share an endovascular arterial approach, consisting of a selective catheterization of the hepatic artery or its branches...

Apelin is an endogenous peptide that is a ligand for the APJ receptor (angiotensin II receptor like-1, AT-1). The apelin/APJ system is distributed in diverse periphery organ tissues. It has been shown that the apelin/APJ system plays various roles in physiology and pathophysiology of many organs. It regulates cardiovascular development or cardiac disease, glycometabolism and fat metabolism as well as metabolic disease. The apelin/APJ system participates in various cell activities such as proliferation, migration, apoptosis or inflammation...

The 3'-azido-3'-deoxythymidine or Zidovudine (AZT) was the first antiretroviral drug used in the treatment of HIV patients, which has good effectiveness but also hepatotoxic side effects that include cell cycle arrest and oxidative/nitrative mitochondrial damage. Whether such an oxidative damage may affect the proliferative-regenerative capacity of liver remains to be clearly specified at doses commonly used in the clinical practice. In this study, we described the oxidative-proliferative effect of AZT administered at a common clinical dose in rat liver submitted to 70% partial hepatectomy (PH)...

BACKGROUND: Wisteria floribunda agglutinin positive human Mac-2-binding protein glycosylation isomer (M2BPGi) is a novel serum glycomarker for liver fibrosis. However, it is not known whether or not M2BPGi reflects only liver fibrosis. We measured serum M2BPGi levels in patients with acute liver injury. METHODS: Fifty-one patients with acute liver injury were enrolled. M2BPGi levels were measured at the initial visit and at achievement of recovery. The relationship between M2BPGi values at the initial visit and clinical outcomes was analyzed...

Alcohol exposure is a major reason of morbidity and mortality all over the world, with much of detrimental consequences attributing to alcoholic liver disease (ALD). With the continued ethanol consumption, alcoholic fatty liver disease (AFLD, the earliest and reversible form of ALD) can further develop to more serious forms of alcoholic liver damage, including alcoholic steatohepatitis, fibrosis/cirrhosis, and even eventually progress to hepatocellular carcinoma and liver failure. Furthermore, cell trauma, inflammation, oxidative stress, regeneration, and bacterial translocation are crucial promoters of ethanol-mediated liver lesions...

The establishment of metabolic zonation within a hepatic lobule ascribes specific functions to hepatocytes based on unique, location-dependent gene expression patterns. Recently, there have been significant developments in the field of metabolic liver zonation. A little over a decade ago, the role of β-catenin signaling was identified as a key regulator of gene expression and function in pericentral hepatocytes. Since then, additional molecules have been identified that regulate the pattern of Wnt/β-catenin signaling within a lobule and determine gene expression and function in other hepatic zones...

Autophagy may have protective effects in renal ischemia-reperfusion (I/R) injury, although the underlying mechanisms remain unclear. Augmenter of liver regeneration (ALR), a widely distributed multifunctional protein that is originally identified as a hepatic growth factor, may participate in the process of autophagy. To investigate the role of ALR in autophagy, ALR expression is knocked-down in human kidney 2 (HK-2) cells with short hairpin RNA lentivirals. Then, the level of autophagy is measured in the shRNA/ALR group and the shRNA/control group in an in vitro model of ischemia-reperfusion (I/R)...
