High throughput functional genomics: identification of novel genes with tumor suppressor phenotypes.

We have used a combination of high throughput functional genomics, computerized database mining and expression analyses to discover novel human tumor suppressor genes (TSGs). A genome-wide high throughput cDNA phenotype screen was established to identify genes that induce apoptosis or reduce cell viability. TSGs are expressed in normal tissue and frequently act by reduction of growth of transformed cells or induce apoptosis.

Development of secreted proteins as biotherapeutic agents.

As one of the most important classes of proteins, secreted factors account for about one-tenth of the human genome, 3000 - 4000 in total, including factors of signalling pathways, blood coagulation and immune defence, as well as digestive enzymes and components of the extracellular matrix. Secreted proteins are a rich source of new therapeutics and drug targets, and are currently the focus of major drug discovery programmes throughout the industry. Many of the most important novel drugs developed in biotechnology have resulted from the application of secreted proteins as therapeutics.
