Spot the differences: proteomics in cancer research.
Separation of thousands of cellular proteins by two-dimensional electrophoresis allows the detailed comparison of proteins from normal and diseased tissue. Mass spectrometry provides a fast and reliable way of characterising proteins of interest, particularly when the gene sequence of the source organism is known. The availability of the human genome sequence has opened up the possibility of identifying protein differences between normal and diseased tissue, thus providing the opportunity to search for tumour markers or for therapeutic targets. This new technology will give much-needed insight into the molecular mechanisms of tumour development and progression.
