ith the complete sequence of the human genome, we now should be able
to analyze whole genomic expression. This will provide vital
information for us to understand the maintenance of health and the
development of diseases, and facilitate the drug discovery process.
However, a complete understanding of normal and disease states can
never be obtained from genomic research alone. Although DNA is
information achieved, proteins do almost all the work in cells. Many important aspects which are vital for
disease development and drug discovery, such as protein-protein interaction,
protein modification and protein-DNA interaction can not be studied
using a genomic approach alone. Therefore, protein analysis is closer to the
actual disease process and offers a more realistic hope of fighting
diseases than genomics.
