Biomarkers are central to the translational medicine strategic focus, though strict criteria need to be applied to their designation and utility. They are one of the most promising areas of medical research, but the "biomarker life-cycle" must be understood to avoid false-positive and false-negative results. Molecular biomarkers will revolutionize the treatment of neurological diseases, but the rate of progress depends on a bold, visionary stance by neurologists, as well as scientists, biotech and pharmaceutical industries, funding agencies, and regulators...

The development of structure-guided drug discovery is a story of knowledge exchange where new ideas originate from all parts of the research ecosystem. Dorothy Crowfoot Hodgkin obtained insulin from Boots Pure Drug Company in the 1930s and insulin crystallization was optimized in the company Novo in the 1950s, allowing the structure to be determined at Oxford University. The structure of renin was developed in academia, on this occasion in London, in response to a need to develop antihypertensives in pharma...

In March 2017, the American biotech company Tonix announced that a Canadian scientist had synthesized horsepox virus as part of a project to develop a safer vaccine against smallpox. The first de novo synthesis of an orthopoxvirus, a closely related group of viruses that includes horsepox and the variola virus that causes smallpox, crosses an important Rubicon in the field of biosecurity. The synthesis of horsepox virus takes the world one step closer to the reemergence of smallpox as a threat to global health security...

Over the past ten years, the global biopharmaceutical market has remarkably grown, with ten over the top twenty worldwide high performance medical treatment sales being biologics. Thus, biotech R&D (research and development) sector is becoming a key leading branch, with expanding revenues. Biotechnology offers considerable advantages compared to traditional therapeutic approaches, such as reducing side effects, specific treatments, higher patient compliance and therefore more effective treatments leading to lower healthcare costs...

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...

There has been substantial growth in the number of physicians pursing Master of Business Administration (MBA) degrees over the past decade, but there is continuing debate over the utility of these programs and the career outcomes of their graduates. The authors analyzed the clinical and professional activities of a large cohort of physician-MBAs by gathering information on 206 physician graduates from the Harvard Business School MBA program who obtained their degrees between 1941 and 2014. Key outcome measures that were examined include medical specialty, current professional activity, and clinical practice...

An important goal of biomedical research is to translate basic research findings into useful medical advances. In the field of neuropharmacology this requires understanding disease mechanisms as well as the effects of drugs and other compounds on neuronal function. Our hope is that this information will result in new or improved treatment for CNS disease. Despite great progress in our understanding of the structure and functions of the CNS, the discovery of new drugs and their clinical development for many CNS disorders has been problematic...

Circulating tumour DNA (ctDNA) is that fraction of circulating DNA that is derived from a patient's cancer. For a number of years, patients with haematological malignancies have had their disease diagnosed or monitored using tests based on detecting specific cytological or molecular biomarkers in blood. It has long been appreciated that the more common epithelial malignancies also shed DNA into the blood and that this tumour-derived DNA generally contributes a minor percentage of the overall cell-free DNA burden in peripheral blood...
