66 results about "Constitutively active" patented technology

Constitutively active: A constitutively active gene is always transcribed, regardless of any regulatory influences. Many, perhaps most genes are constitutively transcribed at some (possibly low) level; however, the level of transcription can be turned up or down by the action of regulatory genes. []

Polypeptides and polynucleotides encoding same and use thereof in the treatment of medical conditions associated with ischemia

An isolated polynucleotide is disclosed comprising a nucleic acid sequence encoding a polypeptide having an amino acid sequence of HIF-1alpha, the polypeptide being stably expressed and constitutively active. Isolated polypeptides encoded by same are also disclosed and uses thereof.

Gene Delivery Vehicles in the Treatment of Neurodegenerative Diseases

ActiveUS20140100265A1Promoting axon regenerationSugar derivativesPeptide/protein ingredientsGene deliveryAxon growth
Currently no therapies that provide either protection or restoration of neuronal function for adult onset neurodegenerative diseases such as Parkinson's disease exist. Many clinical efforts to provide such benefits by infusion of neurotropic factors have failed. An alternative approach such as viral construct transduction may be used to directly activate the intracellular signaling pathways that mediate neurotrophic effects and induce axon growth. Viral construct transduction of dopaminergic neurons with a constitutively active human form of the p70S6K gene—hp70S6K (CA)—was shown to induce axon regeneration from living dopaminergic cell bodies that had no living axons.

Mammalian expression systems

The present invention features mammalian expression systems with improved production yields, and method of using these systems to produce desired proteins. In one embodiment, the expression systems of the present invention comprise genetically-engineered mammalian host cells cultured in a medium that contains an effective amount of heparin or heparin-like molecules. The presence of heparin or heparin-like molecules significantly increases protein production by the cultured cells. The present invention also features the use of constitutively-active components of FGFR-I-mediated signal transduction pathways to improve protein production by cultured mammalian cells. Co-expression of such a component with a protein of interest markedly increases the production yield of the protein of interest.

Identification of ligands by selective amplification of cells transfected with receptors

The invention is directed to a method for identifying substances acting as ligands for transfected receptors by using transfected markers to measure receptor / ligand interactions. The present invention also relates to a method of identifying compounds which act as inverse agonists of the 5-HT2A receptor, the method comprising contacting a constitutively active 5-HT2A receptor with at least one test compound and determining any decrease in the amount of basal activity of the receptor so as to identify a test compound which is an inverse agonist of the 5-HT2A receptor. Such inverse agonists may be used in the treatment of schizophrenia and related psychoses.

Enveloped miroorganism

The invention relates to an enveloped microorganism in whose genome the following components are inserted and can be expressed: I) a nucleotide sequence that encodes a directly or indirectly, antiproliferatively or cytotoxically active expression product or a plurality of said expression products, II) a nucleotide sequence that encodes or is constitutively active for a blood plasma protein under the control of a activation sequence that can be activated in the microorganism, III) optionally, a nucleotide sequence that encodes or is constitutively active for a cell-specific ligand under the control of an activation sequence that can be activated in the microorganism, IV) a nucleotide sequence for a transport system that induces expression of the expression products of components I) and II) and optionally III) on the outer surface of the microorganism or that induces secretion of the expression products of component I) and expression of component II) and optionally component III) and that is preferably constitutively active, V) optionally a nucleotide sequence for a protein used for lysis of the microorganism in the cytosol of mammalian cells and for the intracellular release of plasmids with at least one or more components I) and VI) contained in the lysed microorganism, and VI) an activation sequence that can be activated in the microorganism, and/or that is tissue-specific, tumor cell-specific, function-specific or not cell-specific, for expressing component I). The inventive microorganism is further characterized in that any of components I) to VI) can be present either single or several times, and can be either identical or different.
