Current therapeutic strategies cannot eradicate hepatitis B virus covalently closed circular DNA (HBV cccDNA), which accounts for the persistence of HBV infection. Very recently, the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR‑associated protein 9 (Cas9) system has been used as an efficient and powerful tool for viral genome editing. Given that the primary duck hepatocyte (PDH) infected with duck hepatitis B virus (DHBV) has been widely used to study human HBV infection in vitro, the present study aimed to demonstrate the targeted inhibition of DHBV DNA, especially cccDNA, by the CRISPR/Cas9 system using this model...

EDITORIAL
Pieter Wesseling, Thomas S Jacques
In May 2016, an update of the 4th edition of the World Health Organization (WHO) Classification of Tumours of the Central Nervous System (CNS) was officially released [1]. This revised 4th edition represents a paradigm shift as, for the first time, the definition of multiple CNS tumour entities is now partly based on particular genotypic characteristics. Additionally, compared to the 4th edition (published in 2007), some splitting and lumping of entities occurred because of new insights in the genetic underpinnings of CNS tumours and/or based on more recently published clinico-pathologic studies...

Nitika, Andrew W Truman
Heat shock protein 70 (Hsp70) is an evolutionarily well-conserved molecular chaperone involved in several cellular processes such as folding of proteins, modulating protein-protein interactions, and transport of proteins across the membrane. Binding partners of Hsp70 (known as "clients") are identified on an individual basis as researchers discover their particular protein of interest binds to Hsp70. A full complement of Hsp70 interactors under multiple stress conditions remains to be determined. A promising approach to characterizing the Hsp70 "interactome" is the use of protein epitope tagging and then affinity purification followed by mass spectrometry (AP-MS/MS)...

The islands of the Caribbean are considered to be a "biodiversity hotspot." Collectively, a high level of endemism for several plant groups has been reported for this region. Biodiversity conservation should, in part, be informed by taxonomy, population status, and distribution of flora. One taxonomic impediment to species inventory and management is correct identification as conventional morphology-based assessment is subject to several caveats. DNA barcoding can be a useful tool to quickly and accurately identify species and has the potential to prompt the discovery of new species...

A wealth of fungal enzymes has been identified from nature, which continue to drive strain engineering and bioprocessing for a range of industries. However, while a number of clades have been investigated, the vast majority of the fungal kingdom remains unexplored for industrial applications. Here, we discuss selected classes of fungal enzymes that are currently in biotechnological use, and explore more basal, non-conventional fungi and their underexploited biomass-degrading mechanisms as promising agents in the transition towards a bio-based society...

INTRODUCTION: There are few longitudinal studies of dementia in developing countries. We used longitudinal data from the Maracaibo Aging Study to accurately determine the age- and sex-specific incidence of dementia in elderly Latin Americans. METHODS: The Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition, Text Revision) was used to diagnose dementia, which was classified as Alzheimer's disease, vascular dementia, or other. Age- and sex-specific incidence was estimated as the number of new cases of dementia divided by person-years (p-y) of follow-up...

Bromodomain PHD finger transcription factor (BPTF) is the largest subunit of nucleosome remodeling factor (NURF), a member of the ISWI chromatin-remodeling complex. However, the clinical consequences of disruption of this complex remain largely uncharacterized. BPTF is required for anterior-posterior axis formation of the mouse embryo and was shown to promote posterior neuroectodermal fate by enhancing Smad2-activated wnt8 expression in zebrafish. Here, we report eight loss-of-function and two missense variants (eight de novo and two of unknown origin) in BPTF on 17q24...

BACKGROUND: Whereas evidence supporting the diagnostic value of cardiovascular magnetic resonance (CMR) has increased, there exists significant worldwide variability in the clinical utilization of CMR. A recent study demonstrated that CMR is represented in the majority of European Society for Cardiology (ESC) guidelines, with a large number of specific recommendations in particular regarding coronary artery disease. To further investigate the gap between the evidence and clinical use of CMR, this study analyzed the role of CMR in the guidelines of the American College of Cardiology (ACC) and American Heart Association (AHA)...

The epigenome, which controls cell identity and function, is not maintained with 100 percent fidelity in somatic animal cells. Errors in the maintenance of the epigenome lead to epigenetic drift, an important hallmark of aging. Numerous studies have described DNA methylation clocks that correlate epigenetic drift with increasing age. The question of how significant a role epigenetic drift plays in creating the phenotypes associated with aging remains open. A recent study describes a new DNA methylation clock that can be slowed by caloric restriction (CR) in a way that correlates with the degree of lifespan and healthspan extension conferred by CR, suggesting that epigenetic drift itself is a determinant of mammalian lifespan...

Many mammalian gene expression vectors express the transferred genes under the control of the cytomegalovirus (CMV) major immediate-early promoter (MIEP). The human MIEP has been known as the strongest promoter in mammalian cells and utilized widely in mammalian expression systems. There are four NF-κB binding sites (named as κBs) in the human MIEP. In this study, we have constructed a multiple mutated MIEPs by changing the natural κBs in the human MIEP into the high-affinity artificial sequences that were in vitro selected by using systematic evolution of ligands by exponential enrichment (SELEX) and predicted by bioinformatics...

Almost all archaea and many bacteria achieve adaptive immunity through a diverse set of CRISPR-Cas systems. From 2012, Cas9 has been harnessed by thousands of laboratories for genome editing applications in a variety of experimental model systems. Cas9 is driving innovative applications from basic biology to biotechnology and medicine. However, numerous challenges still remain, such as limited targeting range, toxicity, and potential for off-target mutagenesis. Cpf1 represents a class 2/type V CRISPR RNA-guided endonuclease that is distinct from the type II CRISPR Cas9 nuclease...

Synthetic biology is an emerging discipline, which aims at creating artificial lives or remolding the present organisms to generate new features. To achieve these goals, synthetic biologists need to design and synthesize new genes, pathways, modules or even whole genomes. As these enabling technologies (e.g. gene synthesis, DNA assembly and genome editing) are very important for the progress of synthetic biology, we will focus on the development of these technologies in this review.

Benefited from the rapid development of high-throughput sequencing, genome editing, DNA synthesis and functional genomics, synthetic genomics gains the momentum in this century. The entire genomes of several viruses and one prokaryote have been chemically synthesized and applied to drive normal cellular processes. The first eukaryotic genome synthesis project (Sc2.0) is on-going and about half of the genome has been synthesized and functionally tested. The Human Genome Project-Write (HGP-Write) was proposed in 2016, which pushes the tide of synthetic genomics to a position we have never seen before...

Autism Spectrum Disorder (ASD) is associated with persistent impairments in adaptive abilities across multiple domains. These social, personal, and communicative impairments become increasingly pronounced with development, and are present regardless of IQ. The Vineland Adaptive Behavior Scales, Second Edition (Vineland-II) is the most commonly used instrument for quantifying these impairments, but minimal clinically important differences (MCIDs) on Vineland-II scores have not been rigorously established in ASD...
