Finnish researchers discovered a new anticancer compound using accelerated drug screening process
A team of research scientists from VTT Technical Research Centre of Finland, the University of Turku and the University of Eastern Finland has discovered a previously unknown Cent-1 molecule that kills cancer cells. Their research also shows that new cancer drug candidates can be identified faster and at lower cost by using computer-assisted and cell-based screening of compounds. The objective of the research project led by Marko Kallio, Principal Scientist at VTT, was to accelerate the drug development process by identifying new compounds that would possess similar binding properties and cellular phenotype, but a different chemical structure, as the selected drugs in clinical use or investigational compounds in development.

Shark antibodies inspire optimization of human antibodies
Genetically engineered antibodies are deployed successfully in cancer diagnostics and therapy. Therapeutic antibodies against Alzheimer's disease and multiple sclerosis are currently under development. An important criterion when designing suitable antibody fragments is their stability. Comparing the antibodies of sharks, which are very old from an evolutionary perspective, with those of humans, a team of researchers at the Technische Universitaet Muenchen (TUM) and the Helmholtz Zentrum Muenchen discovered stabilizing mechanisms that can also be applied to optimize custom-tailored antibodies in humans.

New agent may enhance effectiveness of radiotherapy
Scientists from The University of Manchester - part of the Manchester Cancer Research Centre - have demonstrated the potential of a drug to improve the effectiveness of radiotherapy in stopping tumour growth. There is increasing interest in using the body's own immune system to attack tumour cells - a strategy that can be very effective without the side effects associated with conventional chemotherapy.

Atlas shows how genes affect our metabolism
In the most comprehensive exploration of the association between genetic variation and human metabolism, researchers have provided unprecedented insights into how genetic variants influence complex disease and drug response through metabolic pathways. The team has linked 145 genetic regions with more than 400 molecules involved in human metabolism in human blood. This atlas of genetic associations with metabolism provides many new opportunities to understand the molecular pathways underlying associations with common, complex diseases.

CNIO team presents a new strategy to personalise cancer therapies
Tumour cells can accumulate hundreds or even thousands of DNA mutations which induce the growth and spread of cancer. The number and pattern of mutations differs according to the type of tumour, even among those that are classified as part of the same type of tumours. This complexity, which researchers were not aware of just a few years ago, calls for new tools to filter relevant genetic information for the implementation and development of personalised therapies targeted at specific characteristics within each individual tumour.

NCI, NCRI and EORTC working group outline risk-assessment approach for biomarker-driven cancer clinical trials
In an article published in The Lancet Oncology, an NCI (US National Cancer Institute), NCRI (UK National Cancer Research Institute), and EORTC (European Organisation for Research and Treatment of Cancer) working group outline a practical risk-management approach for effective integration of biomarkers into cancer clinical trials. Their work provides the international community with a set of common principles by which biomarkers can be integrated into clinical trials, exchange of data can be facilitated, quality promoted, and research accelerated while simultaneously respecting local approaches and legislation.

Patients report high satisfaction with pain treatment
An international research group with members from the University of Basel, several EU countries, Israel and the USA, analyzed patient satisfaction with pain treatment after surgery. The study based on an extensive multi-national dataset shows that patients actively involved in their treatment report higher levels of satisfaction. Overall, satisfaction seems to be less associated with actual pain but rather with impressions of improvement. The scientific journal "PAIN" has published the results. Every year, millions of surgeries are performed. At least half of the patients suffer from moderate to severe pain after surgery. Well managed postoperative pain is thus an important quality criterion for healthcare providers.
