Bone morphogenetic protein 9 (BMP9) is a recently discovered cytokine mainly secreted by the liver and is a member of the transforming growth factor β (TGF-β) superfamily. In recent years, an increasing number of studies have shown that BMP9 is associated with liver diseases, including nonalcoholic fatty liver disease (NAFLD), liver fibrosis and hepatocellular carcinoma (HCC), and BMP9 signaling may play dual roles in liver diseases. In this review, we mainly summarized and discussed the roles and potential mechanisms of BMP9 signaling in NAFLD, liver fibrosis and HCC.

This study aimed to observe changes in the hydrogen sulfide (HS) system in the blood and liver tissue of rats with hepatic cirrhosis at different stages by studying the effect of HS on the course of hyperdynamic circulation in rats with hepatic cirrhosis. HS concentration in the blood from the portal vein and inferior vena cava of hepatic cirrhosis rat model induced with carbon tetrachloride was detected on the 15th, 30th, and 52nd day. The expression of cystathionine β-synthase (CBS) and cystathionine γ-lyase (CSE) protein, and CBS and CSE mRNA in the liver was detected by immunohistochemistry and reverse transcriptase polymerase chain reaction (RT-PCR), respectively.

Objective: To evaluate the Paris criteria, the revised diagnostic criteria and the simplified diagnostic scoring system in the diagnosis of primary biliary cirrhosis (PBC)-autoimmune hepatitis (AIH) overlap syndrome in Chinese patients.

Methods: Medical records of the patients who were diagnosed with PBC at the Union Hospital and Tongji Hospital, Tongji Medical University, Huazhong University of Science and Technology (Wuhan, Hubei Province, China) from 2003 to 2012 were retrospectively reviewed. The overlap syndrome was diagnosed based on the Paris criteria, the revised criteria and the simplified criteria, respectively.

No direct comparison of tauroursodeoxycholic acid (TUDCA) and ursodeoxycholic acid (UDCA) has yet been carried out in the treatment of liver cirrhosis in China. We designed a double-blind randomized trial to evaluate the potential therapeutic efficacy of TUDCA in liver cirrhosis, using UDCA as parallel control. The enrolled 23 patients with liver cirrhosis were randomly divided into TUDCA group (n=12) and UDCA group (n=11), and given TUDCA and UDCA respectively at the daily dose of 750 mg, in a randomly assigned sequence for a 6-month period.

Objective: To investigate the effects of cAMP-response element binding protein-1 (CREB-1) on transforming growth factor-b3 (TGF b3) mRNA expression and promoter activity in hepatic stellate cells (HSCs).

Methods: Freshly isolated HSCs from rats were divided into six groups: CREB-1 expression plasmid transfected group (C), siRNA-CREB-1 plasmid transfected group (S), negative control group (N), forskolin treated group (F), H-89 treated group (H), and blank group (B). Rats in each group were further sub-divided according to whether (+) or not (-) they were exposed to exogenous TGF b3.

Objective: To investigate the effects of exogenous TGF-β3 on the expression of endogenous TGF-b3 in hepatic stellate cell (HSC).

Methods: HSCs were cultured and divided into two groups: TGF-β3 group and blank control group, the cells of TGF-β3 group were exposed to TGF-b3 (10 ng/ml), whereas the blank control group was not treated. The cells were incubated in the presence of exogenous TGF-β3 and then (1) were harvested at 0h, 1h, 2h, 4h, 12h, 24h, and real time PCR was performed to detect the mRNA expression of endogenous TGF-β3.

Objective: To explore the effects of exogenous transforming growth factor-β3 (TGF-β3) on the activities of its promoter and cAMP-responsive element binding protein-1 (CREB-1) in rat hepatic stellate cell (HSC-T6).

Methods: HSC-T6 was cultured and treated with or without exogenous TGF-β3 (10 µg/L). Then cell extracts, total RNA and nuclear proteins were collected at different time points.

Previous studies have demonstrated that transforming growth factor-β3 (TGF-β3) protected liver against fibrosis in vivo and vitro, but its regulation is poorly understood. In addition, the cAMP-responsive element (CRE) in TGF-β3 promoter is recognized as an important regulatory site for TGF-β3 auto-regulation. Thus, we hypothesize that transcription factor CRE-binding protein-1 (CREB-1) regulates the auto-induction of TGF-β3 in hepatic stellate cells (HSCs).

Objective: To investigate the change of viral titers under different conditions in cultured cells persistently-infected with different strains of Japanese encephalitis virus (JEV) and find out the factors that influence viral multiplication.

Methods: JEV JaGAr-01 and Nakayama wild strains were used to infect human hepatoma cell line KN73 respectively, and the persistent infection model was established. Viral titers were examined by plaque methods using BHK cells.

Angiogenesis is an important process required for cancer. Netrin-1, an axon guidance cue used to guide axon pathfinding and regulate neuron proliferation, may also be involved in the angiogenesis respecting the anatomical similarity of neural and vascular system. Surprisingly, we demonstrate that Netrin-1 has a dual role in regulating angiogenesis.

Background & Objective: Cyclooxygenase-2 (COX-2) protein is highly expressed in hepatocellular carcinoma (HCC). It may be involved in tumorigenesis and development of HCC. This study was to explore the effects of COX-2 short hairpin RNA (shRNA) on COX-2 expression in HCC cell line HepG2 and on adhesiveness and invasiveness of HepG2 cells in vitro.
