Biomarkers for cancer treatment

22 October 2013 | By Amancio Carnero, Instituto de Biomedicina de Sevilla, Consejo Superior de Investigaciones Científicas

There is an urgent need to predict which treatment will report the most benefit to a patient with cancer. To that end, scientists are exploring any possible biomolecule in the organism that can mark each individual for its adequate treatment. If achieved, it will open a personalised medicine era.

Label-free quantitative proteomics: Why has it taken so long to become a mainstream approach?

13 June 2013 | By Thierry Le Bihan, SynthSys and Institute of Structural and Molecular Biology, University of Edinburgh

In recent years, mass spectrometry (MS) based proteomics has moved from being a qualitative tool (used to mainly identify proteins) to a more reliable analysis tool, allowing relative quantitation as well as absolute quantitation of a large number of proteins. However, the developed quantitative methods are either specific for certain…

RNA quality matters

18 December 2012 | By Mikael Kubista, Jens Björkman, David Svec and Robert Sjöback, TATAA Biocenter

RNA levels can be measured with very high specificity, sensitivity and accuracy with techniques such as real-time quantitative PCR (qPCR), microarray analysis and next generation sequencing. This makes messenger (m) RNAs and potentially microRNAs and other non-coding RNAs popular as biomarkers. But RNA is less stable and more dynamic than…

FIGURE 1 Parties involved in the biomarker discovery and validation process. Medical Science is responsible for sample collection, pre-classification and storage in biobanks. Analytical Chemistry is responsible for developing sample preparation protocols and analytical platforms both for comprehensive biomarker discovery on low numbers of samples as well as for the targeted validation in large sample cohorts. Bioinformatics is responsible for performing the data pre-processing and statistical analysis as well as the validation of data and clinical information provided by the analytical and medical partners. A close collaboration and information exchange is essential for the success of biomarker research

Discovery and validation of protein biomarkers

10 July 2012 | By Péter Horvatovich & Rainer Bischoff, Analytical Biochemistry, Department of Pharmacy, University of Groningen

Biomarkers are biological characteristics that are objectively measured and evaluated as indicators of normal biological processes, pathogenic processes or pharmacological responses to a therapeutic intervention. Biomarkers can be used to determine disease onset, progression, efficacy of drug treatment, patient susceptibility to develop a certain type of disease or predict efficacy…

The need for proteomic-based biomarkers in the drug development pipeline

10 July 2012 | By Paul C. Guest, Department of Chemical Engineering and Biotechnology, University of Cambridge and Sabine Bahn Department of Chemical Engineering and Biotechnology, University of Cambridge & Department of Neuroscience, Erasmus Medical Centre

Pharmaceutical companies are under increasing pressure to improve their efficiency and returns on drug discovery projects. This is a daunting task considering that the average drug costs approximately one billion US dollars to develop and takes around 12 years from initial discovery to reach the market1. In addition, approximately 70…

Targeted therapy in metastatic melanoma

28 February 2012 | By Janina Staub and Jochen Utikal, Department of Dermatology, Venereology and Allergology, University Medical Center Mannheim, University of Heidelberg & Skin Cancer Unit, German Cancer Research Center

During the last few years, significant improvements in the treatment of metastatic melanoma were reported, targeting molecules involved in the pathogenesis of melanoma. Different clinical trials were able to prove a prolonged overall survival by introducing new therapeutic agents. Hereby an imunomodulating therapy with the anti-CTLA-4 antibody ipilimumab has been…

Discovery and validation of biomarkers for multiple sclerosis

13 December 2011 | By Ole Pless and Sheraz Gul, European ScreeningPort GmbH

Multiple Sclerosis (MS) is an autoimmune disease leading to a chronic inflammation and degeneration of the central nervous system. It is one of the major neurological diseases with approximately 2.5 million suffering patients worldwide. Until now, the underlying mechanisms have not been fully elucidated, but the cause of the disease…

Expression profiling of circulating miRNAs as a novel non-invasive diagnostic tool

13 December 2011 | By Mirco Castoldi. Department of Pediatric Hematology, Oncology and Immunology University of Heidelberg

Cell-free nucleic acids circulating in human blood were first described in 19481. However, it was not until the work of Sorengon and colleagues was published in 19942 that the importance of circulating nucleic acid (cfNA) was recognised. Today, the detection of diverse type of cfNA3 in blood and other body…

HOX genes: HOX transcription factors as biomarkers in cancer

19 October 2011 | By Richard Morgan, Postgraduate Medical School, Faculty of Health and Medical Sciences, University of Surrey

The HOX genes are a family of closely related transcription factors that help to define the identity of cells and tissues during embryonic development and which are also frequently deregulated in cancer, where they have been shown to promote cell survival and proliferation. The high level of cancer-associated HOX expression…
