The design of screening methods for the detection of genetically modified organisms (GMOs) in food would improve the efficiency in their control. We report here a PCR amplification method combined with a sequence-specific electrochemical genosensor for the quantification of a DNA sequence characteristic of the 35S promoter derived from the cauliflower mosaic virus (CaMV). Specifically, we employ a genosensor constructed by chemisorption of a thiolated capture probe and p-aminothiophenol gold surfaces to entrap on the sensing layer the unpurified PCR amplicons, together with a signaling probe labeled with fluorescein...

Terpenoid flavor and fragrance compounds are of high interest to the aroma industry. Microbial production offers an alternative sustainable access to the desired terpenoids independent of natural sources. Genetically engineered microorganisms can be used to synthesize terpenoids from cheap and renewable resources. Due to its modular architecture, terpenoid biosynthesis is especially well suited for the microbial cell factory concept: a platform host engineered for a high flux toward the central C5 prenyl diphosphate precursors enables the production of a broad range of target terpenoids just by varying the pathway modules converting the C5 intermediates to the product of interest...

Motivation: The Human Protein Atlas (HPA) enables the simultaneous characterization of thousands of proteins across various tissues to pinpoint their spatial location in the human body. This has been achieved through transcriptomics and high-throughput immunohistochemistry-based approaches, where over 40,000 unique human protein fragments have been expressed in E. coli. These datasets enable quantitative tracking of entire cellular proteomes and present new avenues for understanding molecularlevel properties influencing expression and solubility...

Raymond S Norton
Peptide toxins are potent and often exquisitely selective probes of the structure and function of ion channels and receptors, and as such are of significant interest to the pharmaceutical and biotech industries as both therapeutic leads and pharmacological tools. Their progression as clinical candidates, however, faces many of the challenges that are common to peptide drugs generally. Areas covered: The attributes of peptide toxins as therapeutic leads are outlined, as well as some of the limiting factors that have hampered the clinical development of many promising candidates...

Nearly 90 new drugs and biologics, including important new line extensions, were approved or launched for the first time globally in 2016, a comparatively lower number with respect to previous years. Forty-four new drugs and biologics reached their first markets worldwide in 2016, nearly 10% fewer than the previous year. Seven of the new launches were first-in-class agents, meaning the first drug with a novel mechanism of action to be approved and launched anywhere in the world. In addition, 23 novel line extensions (i...

Summary: Due to their chemical plasticity, Cysteine residues (Cys) can serve many different functions. Identification and classification of reactive Cys isn't a trivial job: currently, no available tool exists for an all-round, comprehensive (inclusive of all different functional types) analysis of Cys; herein we present a computational platform called Cp i pe, dedicated to this task: it implements state-of-the art protocols, elaborating and displaying a wealth of information, sufficiently orthogonal to allow a thorough evaluation of all major aspects of Cys reactivity...

Viral infection is a common trigger for acute exacerbations of chronic obstructive pulmonary disease (AECOPD). The aim of this study is to investigate the expression of cytokines in AECOPD. Patients with AECOPD requiring hospitalization were recruited. Meanwhile healthy volunteers of similar age that accepted routine check-ups and showed no clinical symptoms of inflammatory diseases were also recruited. Induced sputum and serum were collected. Induced sputum of participants was processed and tested for thirteen viruses and bacteria...

This focus issue of Lab Animal coincides with a tipping point in biomedical research. For the first time, the scale of the reproducibility and translatability crisis is widely understood beyond the small cadre of researchers who have been studying it and the pharmaceutical and biotech companies who have been living it. Here we argue that an emerging literature, including the papers in this focus issue, has begun to congeal around a set of recurring themes, which themselves represent a paradigm shift. This paradigm shift can be characterized at the micro level as a shift from asking "what have we controlled for in this model?" to asking "what have we chosen to ignore in this model, and at what cost?" At the macro level, it is a shift from viewing animals as tools (the furry test tube), to viewing them as patients in an equivalent human medical study...

INTRODUCTION: Participation in external quality assessment (EQA) is central to the maintenance of high-quality laboratory results in patient diagnosis and clinical trials. Laboratories in the TAF112582 DETECTIVE study (ClinicalTrials.gov identifier: NCT01376167) are enrolled in the United Kingdom National Quality Assessment Scheme (UK NEQAS) for glucose-6-phosphate dehydrogenase (G6PD) quantitative assay, which utilizes ovine (sheep) blood as a readily available source of apparently G6PD-deficient survey material...

This piece describes the approach by which even a small CADD (Computer-Aided Drug Design) group with limited resources and limited time can achieve substantial success given short budgets and the compressed, urgent environment of a biotech. Some comparisons are made with CADD operations in big pharma.

EDITORIAL
Wendy A Warr
A special issue on computer-aided drug design (CADD) strategies in pharma discusses how CADD groups in different environments work. Perspectives were collected from authors in 11 organizations: four big pharmaceutical companies, one major biotechnology company, one smaller biotech, one private pharmaceutical company, two contract research organizations (CROs), one university, and one that spans the breadth of big pharmaceutical companies and one smaller biotech.

The biotech and pharma (biotech/pharma) industry is in dire need of finding ways to increase efficacy, efficiency, and affordability of its products. The information and technology industry ("tech") industry, which is an industry similarly founded on inventions and innovation, may provide some food for thought. This perspective will demonstrate the shift that biotech/pharma is already making and will propose that the industry has an opportunity to compel change by adopting some aspects of the tech industry with regards to models for technology/product development and leadership attributes...

BACKGROUND: The tissue culture banana (TCB) is a biotechnological agricultural innovation that has been adopted widely in commercial banana production. In 2003, Africa Harvest Biotech Foundation International (AH) initiated a TCB program that was explicitly developed for smallholder farmers in Kenya to help them adopt the TCB as a scalable agricultural business opportunity. At the heart of the challenge of encouraging more widespread adoption of the TCB is the question: what is the best way to introduce the TCB technology, and all its attendant practices and opportunities, to smallholder farmers...

Feng-Chi Chen
Biotech patents are facing increasingly stern challenges. The patent statue holds that a multi-step method patent is not directly infringed unless all steps are carried out and attributed to a single entity. When separate steps are performed jointly by two or more parties, those parties are liable for divided infringement if there exists a direct infringement. Possibilities thus exist for unauthorized but non-infringing joint performance, i.e. enforcing a method patent will be difficult if joint performance stands as a valid defense against direct infringement...

Varsha S Joshi, Vijesh Kumar, Anurag S Rathore
Thorough product understanding is one of the basic tenets for successful implementation of Quality by Design (QbD). Complexity encountered in analytical characterization of biotech therapeutics such as monoclonal antibodies (mAbs) requires novel, simpler, and generic approaches towards product characterization. This paper presents a methodology for implementation of QbD for analytical method development. Optimization of an analytical cation exchange high performance liquid chromatography (CEX-HPLC) method utilizing a sigmoidal gradient has been performed using a hybrid mechanistic model that is based on Design of experiment (DOE) based studies...
