miR-484: A Potential Biomarker in Health and Disease.

Disorders of miR-484 expression are observed in cancer, different diseases or pathological states. There is accumulating evidence that miR-484 plays an essential role in the development as well as the regression of different diseases, and miR-484 has been reported as a key regulator of common cancer and non-cancer diseases. The miR-484 targets that have effects on inflammation, apoptosis and mitochondrial function include SMAD7, Fis1, YAP1 and BCL2L13.

Dual-Targeting Nanoparticle-Mediated Gene Therapy Strategy for Hepatocellular Carcinoma by Delivering Small Interfering RNA.

As a gene therapy strategy, RNA interference (RNAi) offers tremendous tumor therapy potential. However, its therapeutic efficacy is restricted by its inferior ability for targeted delivery and cellular uptake of small interfering RNA (siRNA). This study sought to develop a dual-ligand nanoparticle (NP) system loaded with siRNA to promote targeted delivery and therapeutic efficacy.

P-21-activated kinase 1 contributes to tumor angiogenesis upon photodynamic therapy via the HIF-1α/VEGF pathway.

Photodynamic therapy (PDT) is an effective oncotherapy and has been approved for clinical application. Unfortunately, its therapeutic efficacy is usually overshadowed by tumor angiogenesis. Thus, a detailed understanding of the tumor angiogenesis upon PDT is imperative.

Initial 12-h operative fluid volume is an independent risk factor for pleural effusion after hepatectomy.

Pleural effusion after hepatectomy is associated with significant morbidity and prolonged hospital stays. Several studies have addressed the risk factors for postoperative pleural effusion. However, there are no researches concerning the role of the initial 12-h operative fluid volume.

Transarterial (chemo)embolization for curative resection of hepatocellular carcinoma: a systematic review and meta-analyses.

Purpose: To assess the beneficial and harmful effects of transarterial embolization (TAE) or transarterial chemoembolization (TACE) for curative resection of hepatocellular carcinoma (HCC).

Methods: The authors conducted an extensive search of studies on this strategy. All randomized controlled trials comparing TACE or TAE plus operation versus operation only were considered for inclusion, regardless of blinding, language, or publication status.

Antiviral therapy after curative treatment of hepatitis B/C virus-related hepatocellular carcinoma: A systematic review of randomized trials.

Aim: Available published work on the benefit of adjuvant antiviral therapy after curative treatment of hepatocellular carcinoma (HCC) reports controversial results. The objective of this systematic review was to evaluate the effect of adjuvant antiviral therapy on recurrence and survival after curative treatment of HCC.

Methods: We conducted an extensive search strategy.

Serum carbohydrate antigen (CA) 19-9 as a prognostic factor in cholangiocarcinoma: a meta-analysis.

This study was performed to determine the prognostic role of preoperative serum carbohydrate antigen (CA) 19-9 levels in the survival of patients with cholangiocarcinoma. Articles published up to June 1(st), 2010 that evaluated preoperative CA19-9 levels and the prognosis of cholangiocarcinoma were collected for meta-analysis. The required information for calculating individual relative risk (RR) was extracted from the studies, and a combined overall RR was estimated.

The G314S KCNQ1 mutation exerts a dominant-negative effect on expression of KCNQ1 channels in oocytes.

Congenital long QT syndrome is a cardiac disorder characterized by prolongation of QT interval on the surface ECG associated with syncopal attacks and a high risk of sudden death. Mutations in the voltage-gated potassium channel subunit KCNQ1 induce the most common form of long QT syndrome (LQT1). We previously identified a hot spot mutation G314S located within the pore region of the KCNQ1 ion channel in a Chinese family with long QT syndrome.

Congenital long QT syndrome caused by the F275S KCNQ1 mutation: mechanism of impaired channel function.

Congenital long QT syndrome is characterized by a prolongation of ventricular repolarization and recurrent episodes of life-threatening ventricular tachyarrhythmias, often leading to sudden death. We previously identified a missense mutation F275S located within the S5 transmembrane domain of the KCNQ1 ion channel in a Chinese family with long QT syndrome. We used oocyte expression of the KCNQ1 polypeptide to study the effects of the F275S mutation on channel properties.

[Expression and biological activities of arresten in CHO cells].

Objective: To explore the eukaryotic expression of arresten in CHO cells and to investigate its basic biological activities.

Methods: CHO cells were divided into three groups: transfected pSecTag-arresten group, transfected pSecTag group and control group without transfection. PSecTag-arresten was transfected into CHO cells by Lipofectamine 2000 method.
