Imidazoline I1 receptor (I1R) has been recognized as a promising target in the treatment of many diseases, but little is known about its function in liver fibrogenesis. This study aimed to investigate the effect of I1R activation on the development and progression of liver fibrosis. The results showed that I1R expression was decreased in the livers of both patients and mice with liver fibrosis, and in TGF-β-treated hepatic stellate cells (HSCs). Activation of I1R by moxonidine (MOX) significantly inhibited the progression of liver fibrosis in carbon tetrachloride-induced mice and attenuated the activation of HSCs and kupffer cells...

Hepatocellular carcinoma (HCC) is the most common type of cancer and the rapid tumor growth, drug resistance and metastasis are the major problems for HCC therapy. MicroRNAs (miRNAs) involve in various cell biological processes in HCC. ZEB2 plays crucial roles in HCC progression. ZEB2 is regulated by some identified miRNAs, but there needs to find new miRNAs regulating ZEB2 expression for better understanding the molecular mechanism of HCC. In the present study, ZEB2 was identified as a direct target of miR-211-5p, which was a potential oncogene in cancer...

Nonalcoholic steatohepatitis (NASH) is the most prevalent cause of chronic liver disease in the Western world. However, an optimum therapy for NASH is yet to be established mandating more in-depth investigation into the molecular pathogenesis of NASH to identify novel regulatory molecules and develop targeted therapies. Here, we unravel a unique function of Astrocyte elevated gene-1/Metadherin (AEG-1/MTDH) in NASH using a transgenic mouse with hepatocyte-specific overexpression of AEG-1 (Alb/AEG-1) and a conditional hepatocyte-specific AEG-1 knockout mouse (AEG-1(ΔHEP) )...

Cultured epidermal autografts have been used worldwide since 1981 for patients with extensive third-degree burn wounds and limited skin donor sites. Despite significant progress in techniques toward improving clinical outcome of skin grafts, the long in vitro preparation time of cultured autografts has remained a major factor limiting its widespread use. Here, we show that pharmacological inhibition of TGF-β signaling promotes the expansion of human epidermal keratinocytes (HEKs) with high proliferative potential in co-cultures with both murine 3T3-J2 cells and human feeder cells, including dermal fibroblasts and preadipocytes...

Drug liver-induced injury (DILI) due to minocyclin, alpha methyldopa or nitrofurantoin may be responsible for chronic liver damage that mimic the biological and/or histological features of chronic autoimmune hepatitis and, in rare cases, progresses to cirrhosis(1). Olmesartan medoxomil is an antihypertensive drug that acts by blocking the angiotensin II receptor and is metabolized into its pharmacologically active form, olmesartan, in the intestine and in the liver before being released into the systemic circulation...

Ependymoma is a malignant pediatric brain tumor, often incurable under the current treatment regimen. We aimed to evaluate the expression of microRNAs (miRs) in pediatric ependymoma tumors in an attempt to identify prognostic molecular markers which would lead to potential therapeutic targets. Following miR-array expression analysis, we focused on 9 miRs that correlated with relapse which were further validated by quantitative real time PCR (qRT-PCR) in a cohort of 67 patients. Western blotting and immunohistochemistry were used to measure target protein expression in 20 and 34 tumor samples, respectively...

BACKGROUND: Cardiac surgery may cause a serious coagulopathy leading to increased risk of bleeding and transfusion demands. Blood bank products are commonly first line haemostatic intervention, but has been associated with hazardous side effect. Coagulation factor concentrates may be a more efficient, predictable, and potentially a safer treatment, although prospective clinical trials are needed to further explore these hypotheses. This study investigated the haemostatic potential of ex vivo supplementation of coagulation factor concentrates versus blood bank products on blood samples drawn from patients undergoing cardiac surgery...

Reactive oxygen and nitrogen species (ROS and RNS, e.g. H2O2, nitric oxide) confer redox regulation of essential cellular signaling pathways such as cell differentiation, proliferation, migration and apoptosis. At higher concentrations, ROS and RNS lead to oxidative stress and oxidative damage of biomolecules (e.g. via formation of peroxynitrite, fenton chemistry). Peripheral artery disease (PAD) is characterized by severe ischemic conditions in the periphery leading to intermittent claudication and critical limb ischemia (end stage)...

Cancer is one of the leading causes of death globally according to the World Health Organization. Although improved treatments and early diagnoses have reduced cancer related mortalities, metastatic disease remains a major clinical challenge. The local tumor microenvironment plays a significant role in cancer metastasis, where tumor cells respond and adapt to a plethora of biochemical and biophysical signals from stromal cells and extracellular matrix (ECM) proteins. Due to these complexities, there is a critical need to understand molecular mechanisms underlying cancer metastasis to facilitate the discovery of more effective therapies...

It is an ambitious target to improve overall Hepatocellular Carcinoma therapeutic effects. Recently, MW ablation has emerged as a powerful thermal ablation technique, affording favorable survival with excellent local tumor control. To achieve better therapeutic effects of MW ablation, MW sensitizers are prepared for enhanced MW ablation to preferentially heat tumor territory. However, it is still not practicable for treatment of the orthotopic transplantation tumor. Herein, biocompatible and degradable methoxy poly(ethylene glycol)-poly(lactic-co-glycolic acid) (mPEG-PLGA) microcapsules with hierarchical structure have been designed for microwave-induced tumor therapy...
