Disclosed herein are nucleic acid regulatory elements, expression cassettes, expression vectors, and methods for using the nucleic acid regulatory elements, expression cassettes, expression vectors for treating cone cell disorders.

Compositions and methods for plastid transformation and regeneration or development of transplastomic plants, plant cells, plant parts, and seeds are provided. Target sequences for plastid transformation, together with defined sequences of a first homology arm and a second homology arm are provided for the production of recombinant plastid transformation constructs that target specific sites within the plastid genome for transformation, together with methods of using such constructs.

Disclosed herein is a subgenomic promoter library derived from alphavirus. Also provided herein are methods of using the subgenomic promoters to produce antibodies and other molecules.

The present invention relates generally to a gene expression system utilizing an alphavirus replicon and T7 promoter. The system is capable of expressing proteins in the cell cytoplasm without integrating the gene of interest into the genome of a host cell. The invention has a wide range of applications such as producing induced pluripotent cells and vaccines against pathogens and cancers.

An objective of the present invention is to provide an improved negative-strand RNA viral vector and a use thereof, the negative-strand RNA viral vector exhibiting transient high expression of genes loaded in the vector and enabling the rapid removal of the vector after said expression. It was discovered that by adding a micro-RNA target sequence to the NP, P, or L gene of a negative-strand RNA viral vector, it is possible to control the expression of the vector depending on the micro-RNA expressed by the introduction cell. In particular, when a micro-RNA target sequence was added to the NP or P gene, the expression of the vector decreased depending on the micro-RNA, and the removal of the vector was promoted, while the effect was reversed when a micro-RNA target sequence was added to the L gene. The vector can be applied in cell therapy and regenerative medicine and can be used as a therapeutic vector that targets cancer.

The invention relates to the use of a virus, preferably an adenovirus, for producing a medicament. Said virus is replication-deficient in cells which do not contain YB-1 in the core and codes for an oncogene or ongogene product, especially an oncogene protein, which transactivates at least one viral gene, preferably an adenoviral gene, said gene being selected among the group comprising E1B55kDa, E4orf6, E4orf3, and E3ADP.

The present invention relates to nucleic acid regulatory elements that are able to enhance endothelial cell-specific expression of genes, methods employing these regulatory elements and uses of these elements. Expression cassettes and vectors containing these nucleic acid regulatory elements are also disclosed. The present invention is particularly useful for applications using gene therapy, more particularly endothelial cell-directed gene therapy, and for vaccination purposes.

Provided are native promoters comprising polynucleotides isolated from Corynebacterium glutamicum, and mutant promoters derived therefrom, which may be used to regulate, i.e., either increase or decrease, on-pathway and/or off-pathway gene expression. Also provided are promoter ladders comprising a plurality of the promoters having incrementally increasing promoter activity. Also provided are host cells and recombinant vectors comprising the promoters, and methods of expressing ancillary genes of interest and producing biomolecules using the host cells.

Provided herein are compositions and methods for driving high expression of a transgene. Compositions and methods for driving high expression of a transgene comprising one or more human-derived regulatory elements, which, when operably linked to a transgene, can result in high expression of the transgene in one or more cell types or tissues.

Compositions and methods for the inducible expression of genes in eukaryotic cells are provided. Expression of a nucleotide sequence of interest encoding a protein of interest is controlled by a regulatory fusion protein that consists of a transcription blocking domain and a ligand-binding domain. When a cognate ligand for the ligand-binding domain is present, transcription of the nucleotide sequence of interest is blocked. Upon removal of the cognate ligand, the nucleotide sequence of interest is transcribed. The method is useful for large scale bioreactor production of a desired protein of interest in eukaryotic cells.
