Bertrand Jordan,
Emeritus Research Director,
National Centre for Scientific Research
Bertrand R Jordan (CNRS emeritus research director), an academic molecular biologist with particular achievements in the field of molecular immunology, is the founder and coordinator of the Marseille-Nice Genopole genomics consortium and counselor to the CoreBio-PACA technical platform organisation. An early contributor to DNA array development since 1995, he is also a consultant for French (Ipsogen), Dutch (PamGene) and Taiwanese (Phalanx, Dr. Chip) microarray companies, that operate in fields ranging from prognostic and predictive expression profiling in breast cancer, to “companion diagnostics” based on multiplex kinase activity measurement, and to efficient bacterial diagnostics in the food industry. He recently coordinated a book, “Microarrays in diagnostics and biomarker development” (Springer, 2012).

It is clear that in many cases diagnostic, prognosis or prediction cannot be achieved with the measurement of a single biological parameter – i.e. biomarkers need to be comprised of several (often many) measured entities. Microarrays, being inherently multiplex devices, are particularly well suited for the ascertainment of complex patterns correlated to clinical information.
DNA microarrays are an established approach for mutation detection and pathogen characterization (not really a biomarker study), but they have also been used for expression profiles providing diagnostic (Pathwork diagnostics “TOO”, tumor of origin determination), as well as prognostic and predictive information (Agendia “Mammaprint”, breast cancer). Initial enthusiasm about this approach was dampened by the realisation of serious statistical issues in initial data analysis as well as by the requirement for fresh-frozen samples, but these hurdles have now been largely removed.
Protein and peptide microarrays are a more recent entrance in this contest. Beyond “simple” determination of specific antigens or antibodies in patient serum, complex patterns are finding clinical use. In particular, the capability to measure protein activity (not just protein amount) and even to assess drug sensitivity directly in patient samples in a multiplex fashion is opening new areas of application.
Microarrays thus have a place in the field of biomarker discovery and ascertainment that will be resistant to competition from other approaches (e.g. NGS).
