Nutritional regulation of gene expression

The human genome has now been mapped with a complete sequence to follow shortly. The race is on to apply the vast amount of information contained in the billions of base-pairs. Concurrently, there is an increased demand from the public for perceived natural products. The nutritional supplement and pharmaceutical industries are broadening their product lines to meet this ever-increasing demand. As the genetic basis of disease becomes more evident, it is clear that the two industries will be forced to turn their attention to nutrients affecting gene expression. Such nutritional regulators of gene expression, or genomeceuticals (Brudnak, 2001), have enormous potential for therapeutic and prophylactic applications in both industries by affecting the integrity and expression of genes. However, there are caveats to this application, which if unheeded, may have disastrous results. This paper explores the idea behind the burgeoning area of genomeceuticals as well as some potential pit-falls that this novel area harbors. Representative examples are presented with a subsequent discussion focusing on the specifics of the application.
