The purpose of our study was to evaluate soluble matrixmetalloproteinases (MMPs) and their inhibitor (TIMP1) associated to leg ulcer wound fluid in comparison with the tissue localized ones. We aimed to develop an easy-to-perform protocol for the quantification of soluble MMPs / TIMP and associate the obtained levels with the disease stage and prognostic.

Development of Biomarkers for Improved Diagnosis of Active Tuberculosis
Sybille Hunt, Amirkhani A, Cole R, Harcourt R,Hsu M , Marlborough D, Pedersen S, Qiu J, Ranaweera S, Remediakis C, Richards E, SeroaL, Sharp-Paul I, Sloane A, Vizgoft J, Harry J, Lindner R. , Proteome Systems Ltd

Proteome Systems has identified TB proteins in sputa and blood of people diagnosed with TB. Several of these proteins have been prioritised for ongoing validation. This involves generation of sensitive antibodies and optimisation of assays for detection of TB antigens in clinical samples. This presentation will discuss our progress in this program and our strategy for incorporation of these markers into a diagnostic test format.

Determination of the Autoantibody Repertoire in Autoimmune Diseases with Factor Protein Arrays – A new Approach to Personalized Therapies

Recently, we have presented a strategy to identify new marker molecules characteristic for Alopecia areata by combining protein microarray technology with the use of large cDNA expression libraries (Lueking et al., 2005). This strategy is now applied to Juvenile idiopathic Arthritis (JIA), Rheumatoid Arthritis (RA) and Multiple Sclerosis (MS) in a BMBF-funded project.

Usage of Low-Density Oligonucleotide Microarrays for Prognosis Prediction of Colorectal Cancer Patients

This study aimed to find individual up/down-regulated genes associated with progression and metastatic potential of colorectal cancers using low-density oligonucleotide microarrays spotted with genes known to be involved in process of metastasis development. We suppose that focusing on a particular biological pathway may be more useful than genome-wide screening for our purposes.

We report in this study that gene expression profiles of peripheral blood cells may allow early detection and diagnosis of aortic aneurysm. Gene expression profiles of peripheral blood samples collected from 58 individuals diagnosed with thoracic aortic aneurysm (cases) and 36 normal individuals (controls) were analyzed using the Applied Biosystems Expression Array Systems and Human Genome Survey Microarrays.

New Platforms and Systems for DNA Microarrays
B. Henze, B. Saal, D. Drutschmann, K. Wellesen and P. Schüßler, Operon Biotechnologies GmbH

Operon has designed probes of different lengths to various positions in the Open Reading Frames (ORFs) and the results clearly show that 70mers offer the optimal combination of specificity and sensitivity.
