Alcoholic liver disease (ALD) is one of the predominant causes of liver-related morbidity and mortality worldwide. However, effective therapy for ALD is still lacking. Wogonin, a major flavonoid compound, is found in Scutellaria baicalensis Georgi. Accumulating studies have revealed that wogonin possesses anti-inflammatory and anti-tumour activities in various models. However, the hepatoprotective activity of wogonin in ALD is still obscure. In this study, we found that wogonin significantly attenuated inflammatory response in EtOH-fed mice, and reduced the expression of inflammatory cytokines such as TNF-α and IL-6 in EtOH-induced RAW264...

BACKGROUND AND AIMS: Patients with severe exacerbation of chronic hepatitis B (SE-CHB) are at risk of developing acute-on-chronic liver failure (ACLF). Systemic inflammation (SI) is a major driver of ACLF. The aim of this study was to identify characteristics of SI in hepatitis B-precipitated-ACLF (HB-ACLF), which may be distinct from No-ACLF patients with SE-CHB. METHODS: Two cohorts of patients with SE-CHB were enrolled in two tertiary hospitals. The associations between circulating leukocyte counts/subsets and ACLF progression and prognoses were analysed in Cohort A...

BACKGROUND AND PURPOSE: Fenofibrate, a PPARα agonist, is the most widely prescribed drug for the treatment of hyperlipidemia. Although fibrate drugs were reported to be beneficial for cholestasis, the underlying mechanism has not been determined. EXPERIMENTAL APPROACH: Wild-type mice and Pparα-null mice were orally pretreated with fenofibrate for three days, following which ANIT was administered to induce cholestasis. The potent experimental PPARα agonist WY14643 was used to validate the role of PPARα, and the JNK inhibitor SP600125 was employed to explore the role of the JNK pathway in cholestatic liver injury...

BACKGROUND AND PURPOSE: Morin is a natural occurring flavonoid in many dietary plants and has a wide range of beneficial effects on metabolism; however, the mechanism underlying its action remains elusive. EXPERIMENTAL APPROACH: Reporter assay and the Time-Resolved Fluorescence Resonance Energy Transfer assay were used to identify morin as a dual antagonist of LXRα and LXRβ. High fat-diet mixed with morin (100 mg/100 g diet) was administrated to high-fat diet-induced obese or LXRβ(-/-) mice combining with Western blot and RT-PCR analysis to evaluate the pharmacological effect and mechanism of morin treatment...

Alcoholic hepatitis (AH) is the most severe form of alcoholic liver disease. Most studies have focused on short-term prognosis, while factors associated with long-term survival are largely unknown. THE AIMS OF OUR STUDY WERE: 1) to determine the impact of complete abstinence from alcohol on long-term survival and 2) to identify prognostic factors at admission capable of predicting abstinence during long-term follow-up in patients with AH. One hundred and forty-two patients with biopsy-proven AH that survived the first episode were included...

Tanshinone IIA (TSA), a pharmacologically active component isolated from Danshen, may prevent cardiovascular diseases due to its anti-inflammatory, anti-oxidative, and anti-adipogenic effects. Porphyromonas gingivalis, a major periodontal pathogen, may contribute to the progression of atherosclerosis. Here, we studied the effects of TSA on atherosclerosis in ApoE(-/-) mice with P. gingivalis infection. Eight-week-old ApoE(-/-) mice were randomized to (a) phosphate-buffered saline (PBS), (b) P. gingivalis, and (c) P...

Mesenchymal stem cells (MSCs) have attracted attention as a cell source for regenerative medicine. In particular, MSCs have an anti-inflammatory effect by secreting several kinds of bioactive molecules. MSC therapy is now being applied to various gastrointestinal diseases, such as graft-versus-host disease, inflammatory bowel disease, and liver cirrhosis. Therefore, MSC therapy has the potential to be a novel treatment for acute and chronic pancreatitis by suppressing inflammation. Several studies have investigated the effect of MSC therapy on acute and chronic pancreatitis, but the underlying mechanisms remain unknown...

Renal fibrosis is a common pathological pathway of various chronic kidney diseases progressing to end-stage renal disease and is characterized by tubular atrophy, fibroblast/myofibroblast activation and excessive deposition of extracellular matrix (ECM). N-Myc downstream-regulated gene-2 (NDRG2) is reported to be associated with liver fibrosis in rats. However, the biological function of NDRG2 in renal fibrosis remains unclear. Therefore, we investigate the effect of NDRG2 on renal fibrosis and the underlying mechanism of NDRG2 in TGF-β1-induced renal tubular epithelial cells (HK-2)...

The liver and kidneys are often similarly affected by a single disease. This is the case in metabolic, immunological, toxic, and infectious diseases, and in the different congenital malformation syndromes. Also, an enzymatic defect in an otherwise healthy liver or the consequences of advanced liver disease by itself can cause kidney disease as a secondary phenomenon. In this review, we describe numerous pathogenic mechanisms leading to dysfunction or malformations of the liver and kidneys in children. We encourage multidisciplinary management for optimal care...

PURPOSE: As life expectancy in cystic fibrosis (CF) increases, questions regarding its potential impact on cardiovascular health arise. Soluble vascular cell adhesion molecule 1 (sVCAM-1), P-selectin (sP-selectin) are proposed as biomarkers of cardiovascular disease. We aimed to: compare their concentrations in clinically stable CF patients and healthy subjects (HS) and verify whether they independently correlate with CF characteristics. METHODS: Serum sVCAM-1 and sP-selectin levels were measured using ELISA...

Sexual dimorphisms are prevalent in development, physiology and diseases in humans. Currently, the contributions of the genes on the male-specific region of the Y chromosome (MSY) in these processes are uncertain. Using a transgene activation system, the human sex-determining gene hSRY is activated in the single-cell embryos of the mouse. Pups with hSRY activated (hSRY(ON)) are born of similar sizes as those of non-activated controls. However, they retard significantly in postnatal growth and development and all die of multi-organ failure before two weeks of age...

The mouse has been widely used as a model organism for studying human diseases and for evaluating drug safety and efficacy. Many diseases and drug effects exhibit tissue specificity that may be reflected by tissue-specific gene-expression profiles. Here we construct a comprehensive mouse transcriptomic BodyMap across 17 tissues of six-weeks old C57BL/6JJcl mice using RNA-seq. We find different expression patterns between protein-coding and non-coding genes. Liver expressed the least complex transcriptomes, that is, the smallest number of genes detected in liver across all 17 tissues, whereas testis and ovary harbor more complex transcriptomes than other tissues...

We experienced a 38-year-old Japanese male with t(10;19) CIC-DUX4 -positive undifferentiated small round cell sarcoma in the deep abdominal wall. Three months before his first visit to our hospital, he noticed a mass in his right abdominal wall. Computed tomography on admission revealed a solid abdominal tumor 70×53mm in size and multiple small tumors in both lungs. The biopsy of the abdominal tumor revealed undifferentiated small round cell sarcoma, suggestive of Ewing sarcoma. Under the clinical diagnosis of Ewing-like sarcoma of the abdominal wall with multiple lung metastases, several cycles of ICE (ifosfamide, carboplatin and etoposide) therapy were performed...

Recent evidence includes apoptosis as a defense against Trypanosoma cruzi infection, which promotes an immune response in the host induced by T cells, type 1, 2 and 17. Currently, there is no medicine completely preventing the progression of this disease. We investigated the immunological and apoptotic effects, morbidity and survival of mice infected with T. cruzi and treated with dynamized homeopathic compounds 13c: Kalium causticum (GCaus), Conium maculatum, (GCon), Lycopodium clavatum (GLy) and 7% alcohol solution (control, vehicle compounds, GCI)...

CONTEXT: Extra-gastrointestinal stromal tumors (E-GIST) presenting in the liver are exceedingly rare and raise difficult diagnostic and therapeutic challenges. METHODS: We report on two cases of liver E-GIST with different clinical presentations. We describe their clinical and imaging features, their histopathological and molecular characteristics, their treatment and their course. RESULTS: The first case was that of a 56-year-old male presenting with a 10-cm liver mass; the initial diagnosis, made in 1986 from a biopsy sample, was leiomyosarcoma; liver transplantation was performed in 1987; no extra-hepatic tumor was found; the course was uneventful until 1999, when tumor recurrence was diagnosed along the initial biopsy route; after reevaluation of available material, the definitive pathological diagnosis was GIST; imatinib treatment resulted in major response; the patient died of end-stage kidney disease 22 years after the initial diagnosis and 9 years after tumor recurrence...

BACKGROUND AND AIMS: Patient outcome in acute liver failure (ALF) is crucially determined by the appropriate balance between cell death and compensatory cell proliferation. MicroRNAs (miRNAs) - small non-coding RNAs that function as guide molecules in RNA silencing - have evolved as crucial mediators of nearly all developmental and pathological processes including physiology and disease of the liver. We investigated the role of miR-1224 during ALF. METHODS: We measured miR-1224 in livers of mice in various acute liver disease murine models and in ALF patients using quantitative real-time polymerase chain reaction...
