Abstract: A protein having transcription inhibitory activity and lacking at least a part of regions other than a region having DNA binding activity in a transcriptional regulatory factor is provided. This protein can be obtained by isolating cDNA encoding a protein capable of binding to the transcriptional regulatory region of the gene transcription of which is to be inhibited, deleting from the cDNA at least a part of the regions other than the region having DNA-binding activity, inserting the resulting DNA into an appropriate vector, introducing said vector into cells to allow them to express the deleted gene, and isolating and purifying a protein showing the transcription inhibitory activity. For example, the protein can be used in the field of pharmaceuticals as a therapeutic agent. Its use in the field of gene therapy is also expected.

Abstract: The present invention is directed generally to activating gene expression or causing over-expression of a gene by recombination methods in situ. The invention also is directed generally to methods for expressing an endogenous gene in a cell at levels higher than those normally found in the cell. In one embodiment of the invention, expression of an endogenous gene is activated or increased following integration into the cell, by non-homologous or illegitimate recombination, of a regulatory sequence that activates expression of the gene. In another embodiment, the expression of the endogenous gene may be further increased by co-integration of one or more amplifiable markers, and selecting for increased copies of the one or more ampliflable markers located on the integrated vector. In another embodiment, the invention is directed to activation of endogenous genes by non-targeted integration of specialized activation vectors, which are provided by the invention, into the genome of a host cell.

Abstract: A system for automatically creating databases containing industry, service, product and subject classification data, contact data, geographic location data (CCG-data) and links to web pages from HTML, XML or SGML encoded web pages posted on computer networks such as the Internet or Intranets. The web pages containing HTML, XML or SGML encoded CCG-data, database update controls and web browser display controls are created and modified by using simple text editors, HTML, XML or SGML editors or purpose built editors. The CCG databases may be searched for references (URLs) to web pages by use of enquiries which reference one or more of the items of the CCG-data. Alternatively, enquiries referencing the CCG-data in the databases may supply contact data without web page references. Data duplication and coordination is reduced by including in the web page CCG-data display controls which are used by web browsers to format for display the same data that is used to automatically update the databases.
