The present invention relates to modified forms of IL-12. These modified forms of IL-12 may be engineered to have a shortened in vivo half-life compared and/or enhanced localization of biological effects compared to that of corresponding non-modified form of IL- 12. Short half-life and membrane bound forms of IL-12 may provide greater therapeutic control for in vivo therapeutic delivery, in particular when used in combination with ligand inducible delivery of IL-12. Modified forms of IL-12 engineered to have shortened in vivo half-life and/or enhanced localization of biological effects include heterodimeric p35/p40, single chain and membrane bound forms of IL-12 wherein a naturally occurring IL-12 amino acid sequence is genetically modified to enhance susceptibility of the IL-12 molecule to in vivo proteolytic degradation.


The present invention provides diacylhydrazine ligands and chiral diacylhydrazine ligands for use with ecdysone receptor-based inducible gene expression systems. Thus, the present invention is useful for applications such as gene therapy, large scale production of proteins and antibodies, cell-based screening assays, functional genomics, proteomics, metabolomics, and regulation of traits in transgenic organisms, where control of gene expression levels is desirable. An advantage of the present invention is that it provides a means to regulate gene expression and to tailor expression levels to suit the users requirements.

The present invention provides a method for obtaining site-specific recombination in a eukaryotic cell, the method comprising providing a eukaryotic cell that comprises a first recombination attachment site and a second recombination attachment site; contacting the first and second recombination attachment sites with a prokaryotic recombinase polypeptide, resulting in recombination between the recombination attachment sites, wherein the recombinase polypeptide can mediate recombination between the first and second recombination attachment sites, the first recombination attachment site is a phage genomic recombination attachment site (attP) or a bacterial genomic recombination attachment site (attB), the second recombination site is attB or attP, and the recombinase is selected from the group consisting of a Listeria monocytogenes phage recombinase, a Streptococcus pyogenes phage recombinase, a Bacillus subtilis phage recombinase, a Mycobacterium tuberculosis phage recombinase and a Mycobacterium smegmatis phage recombinase, provided that when the first recombination attachment site is attB, the second recombination attachment site is attP and when the first recombination attachment site is attP, the second recombination attachment site is attB. The invention also describes compositions, vectors, and methods of use thereof, for the generation of transgenic cells, tissues, plants, and animals. The compositions, vectors and methods of the present invention are also useful in gene therapy applications.

The present disclosure provides crystalline polymorphic and amorphous forms of (R)-3,5-dimethyl-benzoic acid N-(1-tert-butyl-butyl)-N-(2-ethyl-3-methoxy-benzoyl)-hydrazide (Compound 1) or (S)-3,5-dimethyl-benzoic acid N-(1-tert-butyl-butyl)-N-(2-ethyl-3-methoxy-benzoyl)-hydrazide (Compound 2). The present disclosure further provides compositions comprising crystalline polymorphic and amorphous forms of Compound 1 or Compound 2 and an excipient, methods of making crystalline polymorphic or amorphous forms of Compound 1 or Compound 2, and methods of using crystalline polymorphic or amorphous forms of Compound 1 or Compound 2 to regulate gene expression in a cell or in a subject.


The present invention provides synthetic 5UTRS comprising a first polynucleotide fragment and a second polynucleotide fragment, wherein the first polynucleotide fragment comprises at least one splice site of a first eukaryotic gene, the second polynucleotide fragment comprises at least a portion of 5 untranslated region of a second eukaryotic gene, and the first polynucleotide fragment is located 5 of the second polynucleotide fragment. In one embodiment, the first polynucleotide fragment comprises the second intron of a sarcoplasmic/endoplasmic reticulum calcium ATPase gene and the second polynucleotide fragment comprises at least a portion of the 5 untranslated region (5UTR) of a eukaryotic casein gene. The synthetic 5UTRS are useful for increasing the expression of a transgene when positioned between a promoter and a transgene within an expression vector. The present invention also provides vectors comprising synthetic 5UTRs and methods for increasing the expression of a transgene using synthetic 5UTRs.


This invention relates to the field of biotechnology or genetic engineering. Specifically, this invention relates to the field gene expression. More specifically, this invention relates to novel substitution mutant receptors and their use in a nuclear receptor-based inducible gene expression system and methods of modulating the expression of a gene in a host cell for applications such as gene therapy, large scale production of proteins and antibodies, cell-based high throughput screening assays, functional genomics and regulation of traits in transgenic organisms.

This invention relates to the field of therapeutics. Disclosed are methods of generating conditionally expressing erythropoietin under the control of an ecdysone receptor-based gene expression modulation system in the presence of activating ligand and uses for therapeutic purposes in animals. The methods of the invention cause an in vivo increase in the expression of erythropoietin and an increase in the hematocrit or volume percentage of red blood cells in blood after administration of the ligand.

Multi-carbon compounds such as ethanol, n-butanol, sec-butanol, isobutanol, tert-butanol, fatty (or aliphatic long chain) alcohols, fatty acid methyl esters, 2,3-butanediol and the like, are important industrial commodity chemicals with a variety of applications. The present invention provides metabolically engineered host microorganisms which metabolize methane (CH_(4)) as their sole carbon source to produce multi-carbon compounds for use in fuels (e.g., bio-fuel, bio-diesel) and bio-based chemicals. Furthermore, use of the metabolically engineered host microorganisms of the invention (which utilize methane as the sole carbon source) mitigate current industry practices and methods of producing multi-carbon compounds from petroleum or petroleum-derived feedstocks, and ameliorate much of the ongoing depletion of arable food source farmland currently being diverted to grow bio-fuel feedstocks, and as such, improve the environmental footprint of future bio-fuel, bio-diesel and bio-based chemical compositions.
