Nucleic acid constructs and methods for rendering modifications to a genome are provided, wherein the modifications comprise null alleles, conditional alleles and null alleles comprising COINs. Multifunctional alleles (MFA) are provided, as well as methods for making them, which afford the ability in a single targeting to introduce an allele that can be used to generate a null allele, a conditional allele, or an allele that is a null allele and that further includes a COIN. MFAs comprise pairs of cognate recombinase recognition sites, an actuating sequence and/or a drug selection cassette, and a nucleotide sequence of interest, and a COIN, wherein upon action of a recombinase a conditional allele with a COIN is formed. In a further embodiment, action of a second recombinase forms an allele that contains only a COIN in sense orientation. In a further embodiment, action by a third recombinase forms an allele that contains only the actuating sequence in sense orientation.

The present disclosure provides, among other things, polynucleotide constructs, compositions, and methods of treating a disease or disorder, including administering to a subject in need thereof a composition comprising a polynucleotide construct comprising a 5 UTR, a mRNA encoding a protein of interest, and a 3 UTR.

The present disclosure relates to relates to promoter variants and Corynebacterium mutant strain, and methods of use thereof.

The present invention relates to vectors, such as DNA plasmids, comprising multiple nucleic acid sequences engineered to be co-expressed as separate molecules. Such separate molecules include a first polypeptide, wherein the first polypeptide comprises a targeting unit that targets antigen-presenting cells, a multimerization unit, such as dimerization unit, and an antigenic unit comprising one or more T cell epitopes of a self-antigen, an allergen, an alloantigen or a xenoantigen, and one or more immunoinhibitory compounds

Disclosed in the present invention is a long-acting recombinant human follicle-stimulating hormone-Fc fusion protein (referred to as hFSH-Fc for short) and a preparation method thereof, wherein the hFSH-Fc protein is a dimerized fusion protein and the amino acid sequence thereof successively comprises an hFSH subunit, CTP, an hFSH subunit, a flexible peptide linker and human IgG2 Fc variant from N-terminal to C-terminal. Also disclosed in the present invention is the use of the recombinant hFSH-Fc fusion protein composition in preparing drugs in the animal breeding field.

The invention relates to retinal disorders, and to genetic constructs and recombinant vectors comprising such constructs, and their use in gene therapy methods for treating, preventing or ameliorating a wide range of retinal disorders. The constructs and vectors are particularly useful for treating geographic atrophy (GA) and dry age-related macular degeneration (dry-AMD). The invention extends to the use of the constructs and vectors for reducing complement activation and retinal cell damage and loss. The invention also extends to pharmaceutical compositions per se, and their use in treating, preventing or ameliorating retinal disorders, and reducing complement activation and retinal cell damage and loss.

The present invention describes a novel gene regulatory sequence containing promoter and enhancer sequences of the human cardiac troponin T gene (TNNT2) that directs expression selectively in the cardiac myocyte. The new TNNT2 promoter/enhancer composition can be used to direct adeno-associated virus gene expression or to construct cell-type specific expression vectors or for cardiac specific transgenesis. The use of this new promoter/enhancer composition is demonstrated by expression of an mAKAP shRNA and mAKAP-derived anchoring disruptor peptides useful for the treatment of heart failure.

The present invention provides a triple-mode antibody display system that simultaneously matures, displays and secretes an antibody to a target of interest. An antibody in vivo-matured and complexed with membrane anchored bait can be expressed on the surface of the host cell, while complexed with a soluble bait the antibody is secreted from the host cell. Methods of using the system for identifying binders that bind specifically to an antigen of interest are also provided. Polypeptides, polynucleotides and host cells useful for making the protein binder display system are also provided along with methods of use thereof

Described herein are compositions and methods of using stable cells lines in combination with transient transfection to produce recombinant AAV (rAAV).

The invention provides compositions and methods for treating diseases associated with expression of a tumor antigen as described herein. The invention also relates to nucleic acids comprising a truncated PGK promoter operably linked to a chimeric antigen receptor (CAR) specific to a tumor antigen as described herein, vectors encoding the same, and recombinant T cells comprising the CARs of the present invention. The invention also includes methods of administering a genetically modified T cell expressing a CAR that comprises an antigen binding domain that binds to a tumor antigen as described herein.
