Abstract: The present invention provides a method of transcriptionally modulating the expression of a gene-of-interest. The method comprises contacting a cell which is capable of expressing the gene with an amount of a molecule effective to transcriptionally modulate expression of the gene and thereby affect the level of the protein encoded by the gene which is expressed by the cell. Molecules useful in the practice of the invention are characterized as follows (a) do not naturally occur in the cell, (b) bind to DNA or RNA or bind to a protein through a domain of such protein which is not a ligand binding domain of a receptor which naturally occurs in the cell. Additionally, this invention provides a method for determining whether a molecule known to be a modulator of protein biosynthesis is capable of transcriptionally modulating expression of a gene-of-interest.

Abstract: The present invention provides a method of transcriptionally modulating the expression of a gene of interest, the expression of which is associated with a defined physiological or pathological effect within a multicellular organism. The method comprises contacting a cell which is capable of expressing the gene with an amount of a molecule effective to transcriptionally modulate expression of the gene and thereby affect the level of the protein encoded by the gene which is expressed by the cell. Molecules useful in the practice of the invention are characterized as follows (a) do not naturally occur in the cell, (b) specifically transcriptionally modulate expression of the gene of interest, and (c) bind to DNA or RNA or bind to a protein through a domain of such protein which is not a ligand binding domain of a receptor which naturally occurs in the cell, the binding of a ligand to which ligand binding domain is normally associated with the defined physiological or pathological effect.
