During the 2014-15 Ebola outbreak in West Africa, the United States responded by stratifying hospitals into 1 of 3 Centers for Disease Control and Prevention (CDC)-designated categories-based on the hospital's ability to identify, isolate, assess, and provide care to patients with suspected or confirmed Ebola virus disease (EVD)-in an attempt to position the US healthcare system to safely isolate and care for potential patients. Now, with the Ebola epidemic quelled, it is crucial that we act on the lessons learned from the EVD response to broaden our national perspective on infectious disease mitigation and management, build on our newly enhanced healthcare capabilities to respond to infectious disease threats, develop a more cost-effective and sustainable model of infectious disease prevention, and continue to foster training so that the nation is not in a vulnerable position once more...

Catanionic surfactant mixtures form a wide variety of organized assemblies and aggregates with improved physicochemical and biological properties. The green catanionic mixture C3(CA)2:lichenysin (molar ratio 8:2) showed antimicrobial synergies against Yersinia enterocolitica, Bacillus subtilis, Escherichia coli O157:H7 and Candida albicans. Flow cytometry and viability studies indicated that this catanionic mixture increases the probability of Y. enterocolitica (38.2%) and B. subtilis (17.1%) cells entering a viable but nonculturable state...

Betaine Aldehyde Dehydrogenase (betaine aldehyde: NAD(P)(+) oxidoreductase, (E.C. 1.2.1.8; BADH) catalyze the irreversible oxidation of betaine aldehyde (BA) to glycine betaine (GB) and is essential for polyamine catabolism, γ-aminobutyric acid synthesis, and carnitine biosynthesis. GB is an important osmolyte that regulates the homocysteine levels, contributing to a vascular risk factor reduction. In this sense, distinct investigations describe the physiological roles of GB, but there is a lack of information about the GB novo synthesis process and regulation during cardiac hypertrophy induced by pregnancy...

Monocytes from sepsis patients have mitochondrial DNA (mtDNA) depletion and immune deactivation. Here we find that THP-1 cell immune responses are impaired by experimentally depleting mtDNA, through dysregulated immune signalling, and rescued by interferon-γ treatment.

Guochang Huang, Andrew J Kaufman, Ke Xu, Katia Manova, Bhuvanesh Singh
SCCRO/DCUN1D1, a component of the neddylation E3 complex, regulates the activity of the cullin-RING-ligase (CRL) type of ubiquitination E3s by promoting neddylation of cullin family members. Studies have shown SCCRO regulates proliferation in vitro and in vivo. Here, we show that inactivation of SCCRO results in prolonged mitotic time due to delayed and/or failed abscission. The effects of SCCRO on abscission involve its role in neddylation and localization of Cul3 to the midbody. The Cul3 adaptor KLHL21 mediates SCCRO's effects on abscission, as it fails to localize to the midbody in SCCRO-deficient cells during abscission and its inactivation resulted in phenotypic changes identical to SCCRO inactivation...

Richard Bayliss, Selena G Burgess, Eoin Leen, Mark W Richards
The Myc proteins comprise a family of ubiquitous regulators of gene expression implicated in over half of all human cancers. They interact with a large number of other proteins, such as transcription factors, chromatin-modifying enzymes and kinases. Remarkably, few of these interactions have been characterized structurally. This is at least in part due to the intrinsically disordered nature of Myc proteins, which adopt a defined conformation only in the presence of binding partners. Owing to this behaviour, crystallographic studies on Myc proteins have been limited to short fragments in complex with other proteins...

REVIEW
Edward J Scourfield, Juan Martin-Serrano
The vast expansion in recent years of the cellular processes promoted by the endosomal sorting complex required for transport (ESCRT) machinery has reinforced its identity as a modular system that uses multiple adaptors to recruit the core membrane remodelling activity at different intracellular sites and facilitate membrane scission. Functional connections to processes such as the aurora B-dependent abscission checkpoint also highlight the importance of the spatiotemporal regulation of the ESCRT machinery...

Several therapeutic agents targeting HGF/MET signaling are under clinical development as single agents or in combination, notably with anti-EGFR therapies in non-small cell lung cancer (NSCLC). However, despite increasing data supporting a link between MET, irradiation and cancer progression, no data regarding the combination of MET-targeting agents and radiotherapy are available from the clinic. S49076 is an oral ATP-competitive inhibitor of MET, AXL and FGFR1-3 receptors that is currently in phase I/II clinical trials in combination with gefinitib in NSCLC patients whose tumors show resistance to EGFR inhibitors...

Hardik B Sailor, Hemant A Patil
In this letter, authors propose an auditory feature representation technique with the filterbank learned using an annealing dropout convolutional restricted Boltzmann machine (ConvRBM) and noise-robust energy estimation using the Teager energy operator (TEO). TEO is applied on each subband of ConvRBM filterbank and pooled later to get the short-term spectral features. Experiments on AURORA 4 database show that the proposed features perform better than the Mel filterbank features. The relative improvement of 2...

Double Hit (DH) or Double Expressor (DE) diffuse large B-cell lymphoma (DLBCL) are aggressive Non-Hodgkin's Lymphomas (NHLs) with translocations and/or over-expressions of MYC and BCL-2, that are difficult to treat. Aurora kinase (AK) inhibition with alisertib in DH/DE-DLBCL induces cell death in ~30%, while ~70% are aneuploid and senescent cells (AASCs), a mitotic escape mechanism contributing to drug resistance. These AASCs elaborated a high metabolic rate by increased AKT/mTOR and ERK/MAPK activity via BTK signaling through the chronic active B-cell receptor (BCR) pathway...

Natural products or nutraceuticals have been shown to elicit anti-aging, anti-cancer and other health-enhancing effects. A key target of the effects of natural products may be the regulation of microRNA (miR) expression which results in cell death or prevents aging, diabetes, cardiovascular and other diseases. This review will focus on a few natural products, especially on resveratrol (RES), curcumin (CUR) and berberine (BBR). RES is obtained from the skins of grapes and other fruits and berries. RES may extend human lifespan by activating the sirtuins and SIRT1 molecules...

DNA topoisomerase IIα (Topo IIα) ensures genomic integrity and unaltered chromosome inheritance and serves as a major target of several anticancer drugs. Topo IIα function is well understood, but how its expression is regulated remains unclear. Here we identify the E3 ubiquitin ligase Smurf2 as a physiological regulator of Topo IIα levels. Smurf2 physically interacted with Topo IIα and modified its ubiquitination status to protect Topo IIα from the proteasomal degradation in dose- and catalytically-dependent manners...

REVIEW

Meningiomas frequently display activation of the PI3K/AKT/mTOR pathway, leading to elevated levels of phospho-4E binding proteins, which enhances protein synthesis; however, it is not known whether inhibition of protein translation is an effective treatment option for meningiomas. We found that human meningiomas expressed high levels of the three components of the eukaryotic initiation factor 4F (eIF4F) translation initiation complex, eIF4A, eIF4E, and eIF4G. The expression of eIF4A and eIF4E was important in sustaining the growth of NF2-deficient benign meningioma Ben-Men-1 cells, as shRNA-mediated knockdown of these proteins strongly reduced cell proliferation...

The mechanisms by which human immunodeficiency virus (HIV) circumvents and coopts cellular machinery to replicate and persist in cells are not fully understood. HIV accessory proteins play key roles in the HIV life cycle by altering host pathways that are often dependent on post-translational modifications (PTMs). Thus, the identification of HIV accessory protein host targets and their PTM status is critical to fully understand how HIV invades, avoids detection and replicates to spread infection. To date, a comprehensive characterization of HIV accessory protein host targets and modulation of their PTM status does not exist...

Neuroblastoma, the commonest paediatric extra-cranial tumour, remains a leading cause of death from cancer in children. There is an urgent need to develop new drugs to improve cure rates and reduce long-term toxicity and to incorporate molecularly targeted therapies into treatment. Many potential drugs are becoming available, but have to be prioritised for clinical trials due to the relatively small numbers of patients. Areas covered: The current drug development model has been slow, associated with significant attrition, and few new drugs have been developed for neuroblastoma...
