Bisha Ding, Weiyang Lou, Liang Xu, Weimin Fan
Hepatocellular carcinoma (HCC) has been one of the most highly lethal cancers. The acquisition of drug resistance accounts for the majority of poor effects of chemotherapy in HCC. Non-coding RNAs (ncRNAs) including microRNAs (miRNAs), long non-coding RNAs (lncRNAs) and circular RNA (circRNA) have been well-documented to participate in cancer occurrence and progression. Recently, multiple studies have highlighted the key roles of ncRNAs in chemoresistance of HCC. In addition, accumulating evidence has demonstrated that they can serve as biomarkers in diagnosis, treatment and prognosis of HCC...

Xinyue Yang, Yan Cheng, Guanfang Su
Angiopoietin-like protein 4 is a multifunctional cytokine regulating vascular permeability, angiogenesis, and inflammation. Dysregulations on these responses contribute to the pathogenesis of ischemic retinopathies such as diabetic retinopathy, age-related macular degeneration, retinal vein occlusion and sickle cell retinopathy. However, the role of ANGPTL4 in these diseases remains controversial. Here, we summarize the functional mechanisms of ANGPTL4 in several diseases. We highlight original studies that provide detailed data about the mechanisms of action for ANGPTL4, its applications as a diagnostic or prognostic biomarker, and its use as a potential therapeutic target...

Vascular dysfunction is a common result of diabetes in human. However, the mechanism underlying diabetic vascular dysfunction is not fully understood. Here in this study, we showed that the histone deacetylase 2 (HDAC2) promoted the endothelial dysfunction induced by diabetes. The expression and activity of HDAC2 were up-regulated in vascular endothelial cells from diabetic patients and mice. The expression of HDAC2 was also increased by high glucose stress in isolated human endothelial cells. HDAC2 knockdown repressed the proliferation rate and promoted high-glucose-induced apoptosis of endothelial cells, which was associated with the activation of apoptotic pathways (Bcl-2, Caspase 3 and Bax)...

Co-opting of CRISPR-Cas "Interference" reactions for editing the genomes of eukaryotic and prokaryotic cells has highlighted crucial support roles for DNA repair systems that strive to maintain genome stability. As front-runners in genome editing that targets DNA, the class 2 CRISPR-Cas enzymes Cas9 and Cas12a rely on repair of DNA double-strand breaks (DDSBs) by host DNA repair enzymes, using mechanisms that vary in how well they are understood. Data is emerging about the identities of DNA repair enzymes that support genome editing in human cells...

While it is well established that centrally injected angiotensin II (Ang II) has potent actions on sympathetic nervous activity (SNA) it is less clear whether peripheral Ang II can immediately stimulate SNA. In particular the contribution of cardiac sympathetic nerve activity (CSNA) to the acute pressor response is unknown. We therefore examined the effect of incremental doses of intravenous Ang II (3, 6, 12, 24 and 48 ng/kg/min each for 30 min) on CSNA in eight conscious sheep. Ang II infusions progressively increased plasma Ang II up to 50pmol/L above control levels in dose dependent fashion (p<0...

Amoebiasis is a parasitic disease caused by Entamoeba histolytica This illness is prevalent in poor countries causing one hundred thousand deaths worldwide. Knowledge of the natural resistance mechanisms of rats to amoebic liver abscess (ALA) development may help to discover new pathogenic factors and to design novel therapeutic strategies against amoebiasis. In this work, histologic analyses suggested that the complement system may play a central role in rat natural resistance to ALA. E. histolytica trophozoites disappeared from rat liver within 3 h post-infection with minimal or no inflammatory infiltrate...

The characteristic fold of a protein is the decisive factor for its biological function. However, small structural changes to amino acids can also affect their function, for example in the case of post- translational modification (PTM). Many different types of PTMs are known, but for some, including chlorination, studies elucidating their importance are limited. A recent study revealed that the YjgF family member RidA from Escherichia coli shows chaperone activity after chlorination. Thus, to identify the functional and structural difference of RidA upon chlorination, we studied a RidA homologue from Staphylococcus aureus : YabJ...

World Health Organization recommend HBV immunization at 0, 1, and 6 months. However, studies have suggested that shortening the interval between the first and last HBV immunization can improve completion rates. Less clear is whether accelerated immunization is as immunogenic as standard immunization. Thus, this study aimed to compare the short-term immunogenicity of yeast-derived hepatitis B vaccine in healthy adults immunized on an accelerated or standard schedule. Between June 2013 and March 2014, individuals from Jinfeng and Longmen, China were randomly assigned to receive the vaccine on an accelerated schedule (at 0, 1, and 2 months; n = 201) or a standard schedule (at 0, 1, and 6 months; n = 206)...

A major cause of failure in chemotherapy is drug resistance of cancer cells. Exosomes have been introduced to spread chemoresistance through delivering microRNAs (miRNAs). However, a systematic evaluation of the exosomal miRNA expression profiles responsible for chemoresistance is still lacking. In the present study, miRNA signature differentially expressed in exosomes derived from adriamycin-resistant (A/exo) and parental breast cancer cells (S/exo) were analyzed by microarray and the results were confirmed by polymerase chain reaction...

Reactive oxygen species (ROS) are highly reactive reduced oxygen molecules that result from aerobic metabolism. The common forms are the superoxide anion () and hydrogen peroxide (H2 O2 ) and their derived forms, hydroxyl radical (HO∙) and hydroperoxyl radical (HOO∙).Their production sites in mitochondria are reviewed. Even though being highly toxic products, ROS seem important in transducing information from dysfunctional mitochondria. Evidences of signal transduction mediated by ROS in mitochondrial deficiency contexts are then presented in different organisms such as yeast, mammals or photosynthetic organisms...
