Molecular biology and the clinician

Molecular biology has uncovered informational processes which broadly apply in medicine. The points of attack range from diagnosis at the most fundamental level of information flow to the production of therapeutic agents. This is promoting movement from serendipitous strategies of advance to those of predictive rational clinical design. Specific examples show how three principal types of molecular probe are benefiting a wide range of clinical disciplines and thereby blurring interdisciplinary boundaries. There are signs that current medical training is not making the best use of contemporary molecular biology. The identification of areas in which molecular biology can be usefully applied to medicine requires medical practitioners to be aware of its diagnostic and prognostic potential. Equally, advances are delayed by gaps between laboratory workers and their clinical colleagues. The dilemma is that by creating a specialist discipline of clinical molecular biology we risk it becoming isolated and delay the impact of molecular biology in medicine as a whole. An alternative is to find a means for raising molecular consciousness throughout all disciplines in medicine.
