    摘要: A tissue culture screening system to monitor a transcriptional response treated by a chemical signal interacting with a plasma membrane receptor is provided. The tissue culture screening system includes a cell line containing a membrane receptor, a target gene and a specific receptor selected from the group consisting of a steroid receptor, a vitamin receptor and an orphan receptor. The specific receptor regulates transcription of the target gene. Any of the target gene membrane receptor or specific receptor can be introduced into the cell by an expression vector. In addition to the screening system there is also provided assays for identifying test compounds and chemical signals that regulate transcription or are potential agonist or antagonist neurotransmitters or which regulate indirectly by a membrane receptor binding or regulate transription in the absence of a steroid, vitamin or orphan ligand. There is further provided kits for the assays.

    摘要: The verified cDNA sequences for human, bovine and porcine lactoferrin protein have been used to prepare recombinant lactoferrin for therapeutic and nutritional applications. Regions of the cDNA such as the Fe binding sites can be used to make an hLF polypeptide product. The present invention provides novel plasmids, transfected eucaryotic cells and methods of producing these plasmids and transfected eucaryotic cells. The novel plasmid contains the cDNA for lactoferrin protein. Methods for the production of lactoferrin protein in fungi and bacteria are also provided. Thus, the present invention provides an efficient and economical means for the production of recombinant lactoferrin protein and lactoferrin related polypeptides.

    摘要: This invention relates to gene therapy by using vectors which encode stable MRNA and methods of using such vectors. In particular, this invention relates to vectors which establish controlled expression of recombinant genes within tissues at certain levels. The vector includes a 5' flanking region which includes necessary sequences for expression of a nucleic acid cassette, a 3' flanking region including a 3' UTR and/or 3' NCR which stabilizes mRNA expressed from the nucleic acid cassette, and a linker which connects the 5' flanking region to a nucleic acid sequence. The linker has a position for inserting a nucleic acid cassette. The linker does not contain the coding sequence of a gene that the linker is naturally associated with. The 3' flanking region is 3' to the position for inserting the nucleic acid cassette. The expression vectors of the present invention can also be regulated by a regulatory system and/or constructed with a coating.
